Answer:They almost always consist of 4x, 10x, 40x and 100x powers. When coupled with a 10x (most common) eyepiece lens, we get total magnification of 40x (4x times 10x), 100x, 400x, and 1000x.

Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
Answer:
no
Explanation:
If you have your own ways to do it., and you are doing good in class then do it your way.
Answer:
<h2>The cell will not pass the M checkpoint because its chromosomes will not associate with spindle fibers. or if the cell goes complete division, then the homologous chromosomes will go into either daughter cell.</h2>
Explanation:
As in the cell cycle, there are various checkpoints, which checks the cell in many steps like G1/S checkpoint, G2, M etc. They check the integrity of the genome, if there is any defect in the DNA/chromosome, it arrest the cell cycle.
Centromere is the region on the chromosome which binds with spindle fibers and is used in the separation of chromosomes during anaphase of cell cycle. If there is deletion of centromere, then the separation of chrmosome will be affected. Then the homologous chromosome can either go into one of the daughter cell, so one cell will get 2n+1 and other will get 2n-1.
