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.
Answer:
The resistance of the bacteria to antibiotics is increasing and the disease which were easily treatable using the antibiotics, are now incurable and bacteria becomes resistant.
The overdose and misuse of antibiotics Is a big concern of worry. Every time we use antibiotics, it will kill the bacteria which were sensitive but resistant bacteria will survive and starts growing and this process will increase the growth of the resistant bacteria upon the nest use of the antibiotics.
Also due to unawareness, the use of antibacterial tablets against viral infections also cause increase in resistance of bacteria against antibiotics.
