Answer:
1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.
2 This process is called HOMEOSTASIS
Explanation:
Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.
According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.
<span>If the parent's reproductive cells or gametes contain 12 chromosomes each, the number of chromosomes in the zygote is 24. Fertilization is the fusion of two haploid gametes and results in the creation of a diploid zygote. If two haploid gametes containing 12 chromosomes each fuse, the zygote will have 24 chromosomes (12 + 12 = 24).</span>
Explanation:
D) 75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Answer:
Golgi apparatus in sorting and directing membrane components
Explanation:
The Golgi apparatus has sacs called cisternae. It is present in the cytoplasm of eukaryotic organisms.
It helps in the manufacture of an organelle called lysosome which acts as a digestive enzyme.
The Golgi apparatus helps in sorting out proteins for secretion.
It also helps in the transportation of lipids around the cell.
Explanation:
<h3><u>If the genes were linked:</u></h3>
<u>Parental cross: EW/EW X ew/ew</u>
F1 genotype: EW/ew
F1 Gametes:
- Parentals (more abundant): EW and ew
- Recombinant (less abundant): Ew and eW
<u>Test cross: EW/ew X ew/ew</u>
<u>F2 genotypes:</u>
- Parentals: EW/ew; ew/ew;
- Recombinant: Ew/ew; eW/ew
<h3><u>If the genes are not linked:</u></h3>
<u>Parental cross: EEWW X eeww</u>
F1 genotype: EeWw
F1 gametes: EW, Ew, eW, ew. Genes assort independently, so all of the possible gametes of the F1 individual will have the same probability.
<u>Test cross: EeWw X eeww</u>
<u>F2 genotypes:</u>
- 1/4 EeWw, 1/4 Eeww, 1/4 eeWw, 1/4 eeww
