[#467] Most abundant tissue in the body
Correct Answer

(A) Connective

Explanation

Solution: Connective tissue is the most abundant tissue type in the body. In general, connective tissue consists of cells and an extracellular matrix.

[#468] During which phase or phase of cell division, the morphology of the chromosomes is best studied?
Correct Answer

(C) Anaphase, metaphase

Explanation

Solution: Chromosomal morphology is best observed at metaphase. Metaphase is a stage of mitosis in the cell cycle in which chromosomes are at their most condensed and coiled stage.

[#469] Metaphase is followed by the next phase of mitosis called
Correct Answer

(A) Anaphase

Explanation

Solution: These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis typically overlaps with anaphase and/or telophase.

[#470] It is a process which converts a single-celled zygote into a great number of cells, which then differentiate into tissues.
Correct Answer

(A) Mitosis

Explanation

Solution: Mitosis is a process which converts a single-celled zygote into a great number of cells, which then differentiate into tissues.
