<em>At noon the sun is directly overhead the sun rays fall vertically on the body so the shadow is very short.</em>
<em>So the rays fall vertically on the body. in mornings and evenings the rays fall at inclined position. So shadows are long at mornings or evenings.</em>
Answer:
gravitational potential energy
The skier possesses gravitational potential energy at the top of a slope, which transforms into kinetic energy as he moves down the slope.
Excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.
<h3>What are Excitable cells?</h3>
Excitable cells are defined as those cells that are capable of generating electrical impulses when stimulated. Example of such cells include:
- muscle cells( smooth, skeletal and cardiac)
The artery is made up of higher amount of smooth muscles than the veins therefore, excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

Answer:
Meiosis is a reduction division of diploid cells.(2n) Chromosomes numbers are reduced with each successive division stages of meiosis 1 and 2, to haploid(n).
Cats have 38 diploid somatic (body)chromosome (2n) in the somatic cells and are reduced to 19 new varied haploid cells (n) of chromosomes in the gametes.
In cats, as in other mammals, during spermatogenesis in (seminiferous tublule of testis) and oegensis(in the ovaries);<u>meiotic reduction division</u> reduced the diploid somatic chromosomes to haploid chromosomes in sex gametes.
Therefore 38 chromosomes will be in the somatic chromosomes, while the sex gametes, with double-helical molecules of DNA, at the end of meiosis II will have 19 chromosomes, half of the somatic chromosomes.
Explanation:
The most correct answer is C
