If you stopped eating what would be the first, second, and third organic compound your body would use for energy
Svet_ta [14]
If you stopped eating the first organic compound your body would use for energy is glycogen. The body begins to break down glycogen into glucose, which your cells use as fuel. The second organic compound is fat: body must breaks down fat into fatty acids for energy. The third compound are the organic reserves. The body has<span> not stores of sugar and fat, and starts to use protein reserves.</span>

Primary spermatocytes are diploid (2n) cells with all of the organelles typically found in eukaryotic animal cells. Spermatogene
Aneli [31]

Answer: a. Genetic recombination (crossing over)

b. Can also be explained in terms of crossing over

c. Non disjunction of homologous chromosomes in meiosis 1

Explanation:

The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.

C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.

In horses, black coat (b) is dominant over brown coat (b), and being a trotter (t) is dominant over being a pacer (t). a black h
Tomtit [17]
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents. 
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t

The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt

The black horse that is a pacer that can produce this offspring will be:
Bbtt

Therefore, the brown horse's genotype must be:
bbTt

The offspring will receive b from both parents and t from both parents.
