7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white
kondor19780726 [428]

Answer:

See the answer below

Explanation:

<em>Genotype is the genetic composition of organisms and a gene is made up of two alleles.</em>

a) Since the allele for black is B, <u>the genotype for black chickens would be BB. </u>

b) Since the allele for white is W, <u>the genotype for white chickens would be WW.</u>

c) Since erminette color is heterozygous,<u> the genotype would be BW.</u>

d) Two erminette were crossed:

         BW    x    BW

      BB BW BW WW

i. <em>Probability of having black chick (BB) </em>= 1/4

ii. <em>Probability of having a white chick (WW)</em> = 1/4

iii. <em>Probability of having erminette chicken (BW)</em> = 1/2

Determination of Caloric Content of Three Foods1. Compare the calorimeter that you built to a bomb calorimeter. How are they sim
yulyashka [42]

Answer:

The answers to both parts (1 and 2) are given below.

Explanation:

1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.

2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.

In an analysis of the nucleotide composition of DNA, which of the following proportions will be found?
katrin [286]

Answer:

With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).

Explanation:

The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:

  • <em>Adenine is complemented with Thymine A=T</em>
  • <em>Guanine is complemented with Cytosine G=C</em>

From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:

<em>     A + C = G + T</em>

An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:

<em>     A + C = G + T</em>

<em>     5 + 7 = 7 + 5</em>
