Without _____,humans might have a tail.

Question

Quizplus · Accepted Answer

Apoptosis refers to programmed cell death during development. In humans, the cells that would have become a tail undergo apoptosis, leading to the absence of a tail in humans. Without apoptosis, humans might have retained a tail, as seen in other primates. Choice A (differentiation) refers to the process where cells become specialized in terms of structure and function. Choice B (epigenetics) refers to changes in gene expression that are inherited through cell division but not changes in the underlying DNA sequence. Choice C (cell migrations) refers to the movements of cells during development, which are important for the formation of tissues and organs. Choice E (the maternal gene effect) refers to the influence of maternal genes on the development of the embryo. While it may contribute to the absence of a tail in humans, it is not the primary factor responsible.
