Different types, or isotopes, of oxygen exist in the ocean and are incorporated into the skeletal fragments of animals. What can the ratio of preserved isotopes tell us about climate?

Answers

Answer 1

Answer:

The correct answer is - Certain ratios of oxygen reflect either warmer or cooler ocean temperatures.

Explanation:

Ocean have different isotypes or types of oxygen throughout the ocean and also incorporated in the shells of the marine animals of the particular region and time.

We can found out the climate and more particularly the temperature of the ocean as The more 18^O found in the shell or sediment of the animal, the colder the climate and vice versa, however, it is opposite in relation to that of glacier ice.

When amino acids are degraded for energy or glucose production, their amine groups are incorporated by the liver into ____.

Answers

Answer:

The correct answer is - urea.

Explanation:

In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.

The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2).  This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.

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.

Which answer best defines what the Lotka-Volterra predator-prey model mathematically describes?-The competition among many predator species for a dingle prey species.-The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.-The effect of a predator population on a prey population.-The capture efficiency and assimilation rate of a predator, which is dependent on the number of individuals in a prey population.

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.

The answer is B

Explanation:

As mentioned in this question, carbohydrates, proteins, lipids, and nucleic acids are the basic biomolecules found in nature. They are all polymeric substances, hence, are made up of smaller units called monomers.

Asides from being biomolecules, these four molecules are also referred to as MACROMOLECULES based on their large size and complex nature. Macromolecules are molecules that are relatively large in size composing of an aggregate of monomer. Hence, these biomolecules are macromolecules.

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.
