Draw a flowchart to show how food becomes energy that cells can use. Make as many steps as needed. The entire process needs to be clear to someone who’s learning for the first time about the energy that humans use.

Answers

Answer:

this is the answer from edmentum

Explanation:

The main reason that people eat is to get energy and the energy is used by the body to carry out its daily activities.

It should be noted that when we eat, the food needs to be broken down in order for the body to use them. This is done through the process of cellular respiration.

The energy that is in the food that's consumed by human beings is changed into the energy that's usable by the body cells. For example, the sugars in the foods will be digested into a monosaccharide. Also, the energy that's stored in the glucose is converted to ATP which is vital for the body.

On paper, do a Punnet square with a cross between a star-eyed and a circle eyed.

What are the phenotypes of the offspring? What are the genotypes of the offspring?

Your answer:

Answers

Here you does this help

The phenotypes of the offspring would be a circle with a star eye shape and their genotype would be CS

Star-eye is SS and circular eye is CC.

                              SS     x     CC

                           CS    CS    CS   CS

All of the offspring will have CS as genotypes. Since the CS genotype codes for a circle with a star eye shape, it means that all the offspring will also have a circle with a star eye shape.

Answers

Living organisms can incorporate nitrates into their metabolism.

Nitrates are compounds that we can find in nature, originated in the nitrogen cycle.

Plants can obtain nitrogen in the form of nitrate (NO3-) and ammonium (NH4 +).

Nitrates are absorbed and accumulated by plants, being transmitted to humans through the consumption of vegetables and water.

These compounds, in turn, serve as food for other types of prokaryotes, this time denitrifying metabolism, that is, they decompose nitrite and nitrate ions, and obtain energy to live.

Therefore, we can conclude that the nitrate ion (NO3–) forms some of the presentations usable by animals and plants.

Answers

Answer:

Crossing over, independent assortment, and random fertilization all result in genetically diverse offspring.

During meiosis, which is split into 2 categories (Oocyte meiosis and spermatogenesis), a gamete undergoes a process like mitosis, however it occurs twice. A gamete starts out with twice as many chromosomes as a normal cell (It's a diploid), and before prophase I and metaphase I, crossing over occurs, "mixing up" genetic material. This adds diversity.

Independent assortment means that when a cell receives one allele, it does not influence the chances of getting another allele.

Example, in pea plants, if a cell were to receive a green(G) allele, there's still a 50/50 chance of it receiving either a green(G) allele, or a yellow(Y) allele.

Random fertilization increases the diversity even more. Females can produce a large amount of ova in their lifetime. After mating, the fact that the ova can have any combination of genetic material, and that there's over 40 million potential spermatozoa with different genetic material that could combine with it increases diversity.
