Answer:

The second option is the answer: If elodea is put in a test tube in the dark with BTB, the BTB will turn yellow because photosynthesis will not occur in the dark, but the plant will be going through respiration releasing CO2.

Explanation:

Elodea is an aquatic plant that releases oxygen into its environment during the process of photosynthesis.

Elodea needs the requirements to carry out photosynthesis, but being placed in the dark it can not do so.

However it continues to carry out cellular respiration which results in the increase of carbon dioxide level in the water. This is indicated by the BTB turning yellow from green, the yellow colour is an indication of the higher amount of carbon dioxide present.

A child is prescribed hematopoietic stem cell transplantation for severe combined immunodeficiency disease. what is administered
mezya [45]
The child is administered to use Intravenous immunoglobulin and Pneumocystis caranii pneumonia or PCP prophylaxis. These are used to improve humoral immunity in the child until the time when the transplant is performed.
The child is not recommended to use influenza vaccine in immunodeficiency disease reason being the possibility of acquiring influenza which is severe.
Again the child is not recommended to use varicella vaccine because it can lead to a risk of acquiring chicken pox.
For a child with PCP, we use Dapsone.

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
