CHECKPOINT M in the cell cycle is affected by paclitaxel.
Paclitaxel (PTX) is a compound that is sold under the brand name "Taxol" which is used to treat cancer. G1, G2 and M are the 3 checkpoints where all the chromosomes get attached attached to the spindle fibers. Paclitaxel inhibits the assembly and disassembly of the microtubules and prevents the separation of chromosomes during cell division.

Answer:
Option (B)
Explanation:
The front refers to the transition zone that lies between two types of air masses which are of distinguishable density. It extends both vertically and horizontally. The fronts are divided into 4 types, namely-
(1) Warm front
(2) Cold front
(3) Stationary front
(4) Occluded front.
These fronts are often shown in the weather map by using patterns with different colors, where each indicates a type of front.
On the other hand, air masses refer to the body of air mass that is characterized by having a certain composition of density, temperature and moisture content. It varies from place to place.
Thus, the correct answer is option (B).
Answer:
a. the rough endoplasmic reticulum
Because it is the site of protein synthesis.
and all of the other organelles have no relation to protein and handling especially peroxisomes which detoxifies h202 and helps with intracellular digestion similar to the lysosomes and microtubules only function is for locomotion of prokaryotic cells and some eukaryotic cells like the sperm cell also they make up spindle fibers used to bind and separate chromosomes/chromatids in mitosis and meiosis.
