Even though the tubers are genetically identical why the plants that grow from them may not be the same height ?
please explain
Please answer correctly.
Answers
Answer:
I've grown potatoes on top of loose earth that's covered by a thick layer of loose straw. It allows the green leafy parts to easily push through to the sunlight above while keeping developing tubers protected from light. I've grown them this way because I really enjoy the taste of fresh new potatoes and have no desire to store mature potatoes for winter. I want to get the most baby potatoes possible while not damaging the plants with tiny potatoes not big enough to eat yet. It also keeps the potatoes cleaner than if grown under the soil.
When I start lifting the straw back to pick the largest new potatoes, I can see the development of the other potatoes. While the biggest potatoes are 1 1/2 to 2 inches in size, others range in size all the way down to 1/4 inch or less.
When a specific garden plant blooms, most of the flowers open within a very short time period. Now think of tomato plants. The flowers continue to open over a period of months and both ripe tomatoes, large and small green tomatoes as well as flowers can all be found on the same plant. Not all the fruit will be ripe before cold weather kills the plant.
Potatoes are closely related to tomatoes and like tomatoes, not all the tubers will be full size when the plant dies back. So I'd say it's neither genetics nor environmental factors but the inherent life and growth cycle of potatoes that account for the tuber size difference.
The difference in the tuber size in plants of potatoes and tomatoes does not depend upon its genetics or environmental factors rather it depends upon the inherent life and growth cycle of the plant.
What is the growth cycle in potatoes?Growth cycles are the recurrent fluctuations in the series of deviations from the usual trend of the plant growth. Thus, the growth cycle contractions in the plant include slowdowns as well as absolute declines in the activity, whereas business cycles contractions include only the absolute declines or recessions.
Potatoes are the plant species which are closely related to tomatoes and just like tomatoes, not all the tubers will be full size when the plant dies back in time. So, it is neither the genetics nor the environmental factors but the inherent life and growth cycle of the potato plants that account for the tuber size difference in the plants which are genetically identical to each other.

Answers
Answer:
The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.
Explanation:
The mathematical models of Lotka-Volterra equations explain the existing interaction between species in which prey and predator influence and affect each other. The model follows a few assumptions,
The ecosystem is isolated and closed. There is no migration. The whole individuals are reproductively equivalent. In the absence of the predator, prey shows an exponential growth rate. The prey is in the ideal environment. When there is no prey, the predator population decreases exponentially because of the lack of food. The predator environment is ideal, but it is limited by prey density. The predation rate is proportional to the encounters rate, which also depends on density. The predators affect the prey populations, inducing its decrease proportionally to the number of prey and predators present. The prey population also influences the predator population proportionally to the number of encounters between the two species.In these equations, the variable D is the number of predators, and P the number of prey items.
The parameters are always constant:
• r1: prey growth rate.
• a1: predator hunting success.
• r2: predator growth rate.
• a2: the success of the predator in hunting and feeding.
In nature, many factors affect interactions, such as dense-dependent factors and dense-independent factors. Also, in reality, there are stochastic factors. Stochasticity refers to the variability in the system involving those factors that are affecting or influencing population growth. Stochasticity might be related to good years and bad years for population growth.
In real situations, the compliance of the whole assumption does not occur. The previously mentioned constants might vary, constantly changing the interaction between the predator and the prey. These parameters change in different degrees, resulting in varying circumstances for both species.
When two aqueous solutions that differ in solute concentration are placed on either side of a semipermeable membrane and osmosis is allowed to take place, the water will Group of answer choices exhibit a net movement to the side with lower solute concentration. exhibit a net movement to the side with lower free water concentration. exhibit an equal movement in both directions across the membrane. exhibit a net movement to the side with higher free water concentration
Answers
Answer:
exhibit a net movement to the side with lower free water concentration
Explanation:
The correct answer would be that the water will exhibit a net movement to the side with lower free water concentration.
Osmosis is generally defined as the movement of water molecules through semi-permeable membranes from the region of higher water potential or lower solute concentration to the region of lower water potential or higher solute concentration.
From the definition, it becomes obvious that there would be a net movement of water between the two solutions to the side with higher solute concentration or lower free water concentration.
A cloned mammal is made by removing the DNA from the unfertilized egg of an egg donor, replacing it with DNA from a cell of a mature animal, and then implanting that cell into the uterus of a surrogate mother. The cell then divides and behaves as if it were a regular embryo. Answer the following question(s) regarding a clone.Of whom is the baby a clone?
Answers
Answer:
The mature animal
Explanation:
The baby would be a clone of the mature animal whose DNA was placed in the unfertilized egg before being implanted into the uterus of a surrogate mother.
The DNA of the egg donor has been removed and replaced with the DNA of the mature animal. The surrogate mother is just a mere carrier and has no biological relationship with the clone. The only organism with biological relationship with the clone would be the one that donates its DNA, which in this case is the mature animal.

Explanation:
Why the water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance?
Answers
It is actually not. It is weakly blue which becomes apparent when a lot of it is gathered in one place. It is definitely not very strongly colored though. That is very common. Very few pure simple substances are strongly colored. Pure salt and sugar are transparent and colorless too. In bulk they look white because the tiny crystals scatter light, but snow does the same. A liquid forms one homogeneous mass.
In nature, of course, substances are rarely pure. Therefore not so many things look colorless. It only takes a little bit of a strongly colored impurity to color the whole thing. Just look at Himalaya salt or unrefined sugar or orange juice.
Why is water tasteless?
Because we don’t need to taste it. We get a good idea of the water content of food from the feel of it. Other liquids are usually oils, which feel very different. Besides it is not all that important exactly how much water is in one particular food item, if we need hydration then we drink stuff which is definitely mostly water.
The sense of taste not registering water frees up capacity to detect other things.
Why is water odorless?
Likewise because we don’t need to smell it. There is no real evolutionary advantage to be able to instantly tell the moisture content of the air. Better to use the sense of smell to detect poisons, food nearby, relatives or strangers etc. than to tell how the weather is today. We can tell how the weather is by other means.
Answer:
Water is inorganic, transparent, delicate, odourless, and almost colourless.
Explanation:
How colourless is the water?
In fact, it isn't. It's weakly blue, and when many of them are gathered together, it gets obvious. However, it's obviously not very colourful. This is a pretty common occurrence. Very few simple materials are coloured intensely. Pure salt and sugar are also colourless and clear. They look white in mass because the little crystals disperse light, but the snow does the same. A fluid forms a uniform bulk.
Substances are seldom pure in nature, of course. Not so much looks colourless, therefore. It takes just a few colourful uncleanness to colour the whole thing. Look for Himalayan salt or sugar or orange juice unprocessed.
Why is water odourless?
We don't have to taste it because of this. From that feeling, we obtain a decent estimate of the water content of food. The oils, which feel much different, usually are other liquids. Moreover, the exact amount of water in a certain food item is not all so important, if we need moisture we will certainly drink things that are primarily water.
The sensation of taste without water releases the ability to discern other things.
Why does water smell?
We don't have to smell it, too. There is no genuine advantage of being able to identify the humidity of the air instantaneously. It's better to use the sense of smell to detect poisons, nutrients, relatives or strangers, etc. IN various ways, we can tell how the weather is.

Which is an example of temporal isolation?
flowers that bloom in different months
birds that have different mating calls
fruit flies that mate in different locations
squirrels that have different fur colors
Answers
Flowers that bloom in different months is an example of temporal isolaton.
What is temporal isolation?Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.
Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

C. They have a greater surface-to-volume ratio.
O
D. They have a lower surface-to-volume ratio.
Answers
Answer:
C. They have a greater surface-to-volume ratio.
Explanation:
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

Which statement about inheritance is true?
Girls get most of their traits from their moms; boys get most of their traits from their dads.
Male offspring will always have an X-linked genetic disease if the mom is a carrier.
Fathers always determine the gender of the offspring in humans.
Males never have Y chromosomes.
Answers
Answer:
The correct answer is the third statement.
Explanation:
In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.
When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
This is wrong. Parents gender does not affect traits passed on.
Males never have Y chromosomes.This is wrong, Males have to have a Y chromosome. (XY)
Male offspring will always have an X-linked genetic disease if the mom is a carrier.This is wrong. The male offspring have a 50/50 chance if the mother is a carrier, if she has the deseace than all the sons will have the decease.
Correct answerFathers always determine the gender of the offspring in humans.This is because the mom is XX and the dad is XY. The mom gives the X in the gene, and the dad gives the X for daughters (X,X) and gives the sons a Y (X,Y) Males are always XY.
If the mom is a carrier, h, then it will get passed down 50% of the time, and when it gets passed down to the males, they wiill have the deseace. If the mom passes the deacease down to the daughters, 50% will be a carrier too if the dad does not have the deseace. If the dad has the deacease, than 50% of the daughters will have the deacease, and the other 50% will be carrier, and still, 50% of the sons will have the deacease, while the other 50% will be completely clean. So in total 25% of the offspring will be a carrier, 50% will have the deacease, and the other 25% will not have the deacease or be a carrier.

why do wild plants need to reproduce sexually as well as asexually ?
Please answer correctly
Answers
Answer:
Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.
Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.
What are wild plants?Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.
A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.
Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

Answers
Answer:
the molecules are farther apart in ice than in liquid water.
Explanation:
The correct answer would be that the molecules of water are farther apart in ice than in liquid water.
Water molecules in ice form are usually less dense than water molecules in liquid form. The water molecules in ice usually arrange themselves in a lattice form, unlike the random form in liquid water. This arrangement makes water molecules in ice to be more evenly spread out than in their liquid counterpart. Thus, ice is usually less dense than liquid water and will obey the principle of flotation by floating on water.
The ice in the cup is floating is due to: the molecules of water are farther apart in ice than in liquid water.
The density of a substance is the mass of the substance per unit of its volume. The formula to calculate the density is :
[tex]D = \frac{m}{v}[/tex], where D = density, m = mass of the substance, and v = volume
The density is the factor that determines if a substance will float or sink. The less-dense substance floats whereas, the more-dense object sinks.When water freezes to form ice then water molecules show expansion to create an open cage-like structure.This cage-like structure decreases the density of ice than the water so mass ice will have more volume as compared to liquid water.Thus, the ice floats on water - the molecules of water are farther apart in ice than in liquid water.
