Answer:

<u>Functions of epithelial tissue:</u>

i. Epithelial tissue covers the body outside and lines the various cavities inside.
ii. Epithelial tissue lines the hollow organs, body cavities, blood vessels and ducts.
iii. Cells are rested on thin, doubled layered, non-cellular basement membrane.
iv. Epithelial tissue has nerve supply of its own.
v. Epithelial tissue is avascular (a = without, vascular = vessel), i.e. it lacks its own blood supply and hence, obtains nutrients which diffuse out of blood vessels.
vi. Epithelial tissue has the power of division and regeneration. The old injured dead cells are sloughed off regularly and are replaced by new ones.

Answer:

The question lacks the illustrative diagram, the diagram has been attached as an image.

The correct answer, according to the picture is A.

Explanation:

All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.

At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.

Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).

Option B depicts only one replicated chromosome

Option D depicts separation of sister chromatids (only one chromosome)

Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II
