Answer:

B) Coating of microbe to aid phagocyte recognition

Explanation:

Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.

The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.

Thus, Option-B is the correct answer.

Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells

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.

valentina_108 [34]

Answer:

Answer;

A specific sentence.

If a chromosome is like a book, then a gene is like a specific sentence.

Explanation:

A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes. A gene is a molecular unit of heredity, it is a segment of DNA that provides the code to construct a protein.

Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitos
