Question

what are the three sub-phases of interphase*
endocytosis, exocytosis, protein channel
prophase, metaphase, anaphase
g1, s, g2
m phase, mitosis, cytokinesis
meiosis has 2 stages, each consisting of 4 stages each. *
true
false
in humans, the haploid number of chromosomes is _.*
23
46
68
92

Explanation:

• First question: Interphase is part of the cell cycle. The three sub - phases are G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis). Endocytosis and exocytosis are transport mechanisms, prophase, metaphase, anaphase are mitotic phases, and M phase includes mitosis and cytokinesis.
• Second question: Meiosis has two stages (meiosis I and meiosis II). Each stage has four sub - stages: prophase, metaphase, anaphase, and telophase.
• Third question: In humans, diploid cells have 46 chromosomes. Haploid cells (gametes) have half of that number.

Answer:

• First question: G1, S, G2
• Second question: True
• Third question: 23
