Answer 1

1)CENTROSOMES/CENTRIOLES:- Acentrosome is an organelle that is found close to the nucleus within the cytoplasm of cells.Centrosomes are key to the division of cells and produce the spindle fibers that are required during metaphase of mitosis. ... Each centriole is a cylindrical array of 9 microtubules.

2)The melting of the polar ice caps is caused by the overall increase in global temperature, and this melting can have serious consequences for all organisms on Earth. Besides being important for marine life, ice caps help regulate sea level and global temperatures.
