LIFSCI 7B XL - Animation: Meiotic Cell Division Copy Questions and Answers 100% Pass Question: What is the primary purpose of meiosis in cell biology? Answer: The primary purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes as the parent cell, facilitating sexual reproduction and genetic diversity. Question: How many stages are there in meiosis, and what are they called? Answer: Meiosis consists of two main stages: Meiosis I and Meiosis II...

Sister chromatids are which of the following? a. Found right after a cell divides. b. Formed when chromatids separate during cell division. c. Unique to prokaryotes. d. Tightly linked together at a centromere. e. Made only of DNA - Answer-d. Tightly linked together at a centromere. Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you re...

AP Biology Questions and Answers (Graded A) The resting membrane potential depends on which of the following? I. Active transport II. Selective permeability III. Differential distribution of ions across the axonal membrane A. III only B. I and II only C. II and III only D. I, II, and III D The resting potential depends on active transport (the Na+K+-ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads to a differential distribution of ...
