Why are there more overweight people than overweight animals?
aleksandr82 [10.1K]
Humans can will themselves to eat more, as we know that food comes easy to us.

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

In a closed system, the total energy prior to an energy transformation is _______ the total energy after. A. equal to B. unrelat
nikklg [1K]
Hey there mate!

Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.

But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.

So, it really depends whether the system closes up, or whether it would be free of energy.

So, in this case, your correct option to this answer would be (option A).

<span>In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after. 

I hope this helps you!</span>
