Which best explains the role of chlorophyll in photosynthesis?

Tasya [4]

Answer:

B. absorbs energy from the Sun

Explanation:

This is what Chlorophyll does. Chlorophyl's main job is to collect the energy from the sun, and then, it can help the plant make the glucose (plant food).

Look at picture for more explanation. (with picture explanation coming below Extra info)

Extra info:

I learned in my class, that Chlorophyll is on the top most layers under the epidermis and dermis of the leave's skin. There is first the Epidermis, then there are lots and ltos of chloroplast cells, then there are chlorophyll cells in it.

With Picture explanation:

1st image:

The first image shows the leaf's structure. First, you can see the epidermis (on the top), then you can see all those light green round-edged-boxes, those are all the chloroplast cells, then, inside them, are darker green cells, they are the chlorophyl cells.

2nd image:

The second image shows the structure of a chloroplast cell.

The giant light green part on the outside is the chloroplast, then inside that, there are green things, which are the chloroplast, (here they are called thylakoid, because that's the scientific word for it). And then, the other things shown are just extra info.

Name two cell structures found in plant cells but not in animal cells, and describe their functions.

stich3 [128]

Chloroplasts: work to convert light energy of the Sun into sugars that can be used by cells. (photosynthesis)

Vacuoles: Main function is just a space-filler but can also fill digestive functions and their interiors can be used as storage for nutrients.

A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia a

bezimeni [28]

Answer:

Explanation:

The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.

Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.

Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.

Assuming the genotype of the father is AA:

SS x AA

AS AS AS AS

All the children would be normal in this case.

Assuming that the genotype of the father is AS

SS x AS

AS SS AS SS

50% of the children would have sickle cell while the remaining 50% would be normal.

Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach

RUDIKE [14]

Answer:

The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.

It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.

If the problem lies in the stomach it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.
