Answer:
The muscle must change its contraction, wave summation and twitch mode.
Explanation:
Muscle tissue is important for the contraction and movement of an organism. Muscles contain important protein like actin, myosin and troppomyosin that helps in the movement of a particular part of a body.
While lifting a box, if someone put extra weight the muscle will shift from isometric to isotonic contraction. The muscle decreases the wave summation and turns to fast twitch mode for the continuous contraction and lifting the box.
It's something to do with the fact that having sickle cell anaemia reduces the chances of contracting malaria, obviously a very common disease in Africa. I'm not quite sure what the link is but hopefully this helps a little bit?
Answer: The correct answers are-
1) C) S Phase
2) A) prophase, metaphase, anaphase, telophase.
Cell cycle corresponds to the division of cell, which occurs primarily through two phases that are - Interphase ( which has G1, S, and G2 phase) during which cell grows, duplicates its genetic material and M ( mitotic phase) phase during which cell divides.
S phase ( synthesis phase) corresponds to the duplication of the genetic material (DNA). It takes place place after G1 ( Gap 1 phase) phase.
2) Mitosis is a type of cell divison in which one parent cell divides to produce two daughter cells with same number of chromosomes. Prophase is the first phase, followed by metaphase, anpahse, and telophase.
