This indicated that Photosynthesis was occurring.

Photosynthesis- Green plants employ a process called photosynthesis to produce their own sustenance. Life on Earth depends on photosynthesis. Without it, there wouldn't be any green vegetation, and there wouldn't be any creatures either. Interactive. Sunlight, <u>chlorophyll</u>, water, and carbon dioxide gas are necessary for photosynthesis.

Chlorophyll- Chlorophyll is a pigment found in certain living creatures and all green plants. It is necessary for the process of photosynthesis, which turns light energy into chemical energy. The pigment chlorophyll is what gives plants their green color.

Pigment- A chemical that may be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants.

In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between
irga5000 [103]

Answer:

Answer:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair          3/4

ss                  1/4          Long hair          1/4

Explanation:

Both are heterozygous for the trait so we can expect that the cross would be:

Ss x Ss

   S     s

S  SS   Ss

s   Ss   ss

So the resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair:  1/4

So in summary:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair        

ss                  1/4          Long hair          1/4

According to the author, how has the almond tree
DENIUS [597]

Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.

The only way you can answer this question is by reading the text. During this reading, you will notice that there is an element in monoculture that is harming bees, making them have a very difficult life or even die. This element is what is affecting the bees. The author will show why this element is harmful to bees through sentences that prove the effect that this element promotes and how it only exists in monocultures. These sentences will be the text evidence.

It is likely that the author shows how monoculture requires a large use of pesticides, which ends up harming the life of bees. He can also show that monoculture decreases the availability of food for bees, since all monoculture plants only flower once a year and leave the bees without food for the rest of the year, as there is no plant diversity in the monoculture.
