Please answer 5&6. Thank you.

Answer:

5. The correct answer would be an option A. ova

Note: I assume that all the samples are of human origin.

DNA (deoxyribonucleic acid) content of somatic cells of humans consists of 46 chromosomes or 23 pairs of chromosomes. Gametes (sperm or ova) are haploid cells produced by the process of meiosis and contain half the number of chromosomes found in parent cell. Hence, they contain 23 chromosomes.

6. The correct answer would be an option J.

Sperm formation or spermatogenesis is the process by which spermatozoa (haploid gamete) is produced from germ cell with the help of meiotic division.

Meiosis results in the formation of four haploid (n) cells from single diploid (2n) parent cell. Here, 2n is given as 8 so, n would be equal to 4.

Meiosis I results in the formation of two secondary spermatocyte cells (both haploid or 4 chromosomes in this case) from single primary spermatocyte (diploid or 8 chromosome in this case).

Both the secondary spermatocytes undergo meiosis II to produce 4 spermatids (each haploid or 4 chromosome in this case). Spermatids differentiate and mature into spermatozoa.

What are two possible factors that contribute to this country having the most deaths? Which country has the highest percentage o
Nataliya [291]

Answer:

Population density and transportation, Switzerland (technically), Africa

Explanation:

population density means of the population is close together and as such it can spread easier. Modern transportation I.E. buses, planes, railroads can transport large numbers of infected people to several different places within a nation and lead to more cases Switzerland is the highest per capita it has 1340 confirm cases per 1 million people however that's likely because they are able to test a large amount of the population at once whereas a larger Nations such as the u.s. or China is unable to test all their population at once and get accurate results. Africa is least affected due to not having a lot of population some together with the exception of some major cities and more industrialized countries such as Egypt and also Lacking the modern transportation systems available in more industrialized nations they don't have as many trains they don't really have too many planes able to transport infected people everywhere
