1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?

Answer:

The effect is to promote a cycling of the elements, ensuring that they are used and later available again. This is an extremely important factor, as some elements are essential for living beings, and their constant use, without replacement, could lead to the extinction of species.

Explanation:Biogeochemical cycles are processes that occur in nature to ensure the recycling of chemical elements in the environment. It is these cycles that enable the elements to interact with the environment and living beings, that is, they ensure that the element flows through the:

The main biogeochemical cycles found in nature are the:

the answer is the effect of the biogeochemical cycle is it makes chemical elements reusable in nature.

Explanation:

22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.

Perimeter equation is L+L+W+W

We know 7.5 is the length (could also be the width, it doesn't matter the order)

The length appears two times, so lets plug it in-

22.6= 7.5+7.5+W+W  , Now you want to combine the like terms so.. 7.5+7.5=15

22.6= 15+W+W

Now subtract the 15 from 22.6

7.6= W+W , there are two W's left so divide 7.6 by 2

7.6/2= 3.8

It is 3.8 m wide

The structure is known as the mitochondrion and it has an oval shape in

which series of reactions takes place to produce energy needed by the cells

of organisms.

The mitochondrion is regarded as the power house of the cell because

cellular respiration takes place which produces ATP. The ATP formed is the

Green eyes

Explanation:

The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer.

The rarest eye color in the world is green, only 2% of the population in the world have green eyes. To find out more about the list.....

Only 2% of people in the world are believed to have this eye color. It is most easily found in northern and Southern Europe and Western Asia.

They are reddish-brown, with a golden and coppery undertone. Among the clear and beautiful eyes in the world, and according to the survey, the most iris, all eyes and beautiful in the world are according to the study, all eyes are rare and specific.

It is generated by the body thanks to some genetic changes. The most common is albinism, a disease that lowers melanin levels. Because of this, the hair and eyes can be distinguished.

With this information, we can conclude that there are several eye colors, but the most rare is the color green.

Answer:  light intensity, carbon dioxide concentration and temperature i think- maybe

Explanation:

Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either

To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.

Explanation:

A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

D. She needs to know the genotype of the second plant.

A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.

Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

Answer:

It will lose 1 electron

Its charge will be 1+, or simply (+)

Explanation:

Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.

The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+

For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+

Answer:

Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.

hope this helps ☆☆☆

The leaves and rhizomes of the plant are found to act both as a source and a sink when growing and when they perform photosynthesis.

Source organs are the organs which provide a net uptake of resources while sink organs are the organs which have a net drawdown of resources in the plant. Molecular mechanisms which are responsible for the regulation of the relationship between the sources and sinks. These molecular mechanisms include both the carbon and nitrogen-containing metabolites, plant hormones and genes.

Some organs in the plant are found to act both as a source and a sink. Leaves of the plant are sinks when growing and as source when photosynthesizing in the presence of sunlight during daytime. Rhizomes are the sinks when growing however they become sources in the spring season when they provide energy for the new growth.
