The cell of humans contains 46 chromosomes and is about to undergo cell division. Cells are to the parent cell after MEIOSIS

The cells are Identical with the parent

Explanation: During meiosis when cell division occur through the process of cytokinesis at the telophase ( the division of the cytoplasm into two) the daughter cells contain equal number of chromosome with the parent.

They have the same Identity with the parent each cell containing 46 chromosome as the parents.

Reduction in chromosome number occurs in gametic cells as the body chromosome number is reduced to half 23 chromosome

b. heterotroph

explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
