Answer:
D) 38
Explanation:
Most eukaryotes use meiosis as a type of cell division to produce reproductive cells, also known as gametes, this cells are used for sexual reproduction where they fuse together in a process known as fertilization. Somatic cells are diploid while gametes are haploid.
Diploid = 2 (n)
Haploid = n
If the gametes are haploid and contain 19 chromosomes (n= 19), somatic cells must have twice the number (2 * 19 = 38). Options A, B or C are not possible be.
In general, the warmest biomes in the world are found near the equator due to solar radiation is higher at these latitudes.
<h3>What is the Equator line?</h3>
The Equator line is an imaginary line that divides the Earth planet into two approximately equal parts.
Latitudes near the Equator receive perpendicular solar radiation rays and therefore they are the warmest.
At higher latitudes, solar radiation is spread over the Earth's surface and therefore it loses more heat when compared to lower latitudes near the Equator.
In conclusion, the warmest biomes in the world are found near the equator due to solar radiation is higher at these latitudes.

Answer:
Males with XYY syndrome have 47 chromosomes, two of which are Y chromosomes. Most cases of XYY syndrome are due to a cell division error in the sperm prior to conception. Rarely, the cell division error occurs after conception resulting in a mosiac of cells with 46 chromosomes and 47 chromosomes.
Explanation:
DNA is double stranded describes the difference between DNA and RNA.
<u>Explanation:</u>
Deoxyribonucleic acid refers to DNA stands for and ribonucleic acid refers to RNA. Information related to genes is carried by both RNA and DNA. Although they are similar in this way there are many differences that exists between them.
Sugar deoxyribose is contained in DNA whereas the sugar ribose is the content of RNA. Double-stranded molecule is DNA whereas while single-stranded molecule is RNA. In alkaline conditions DNA is stable but RNA is not stable. B-form double helix is the structural feature of DNA. A-form helix structural feature of RNA.
