In order to yield a
chromosome condition, only one sperm can fertilize one egg.
(haploid,
diploid)

For the yield of a diploid condition, one egg can be fertilized by only one sperm.

Explanation:

All body cells except germ cells are diploid which means, they have 2 sets of chromosomes while the germ cells are haploid which means, they have one set of chromosomes.

It is in the diploid condition, one sperm with 'n' set of chromosomes and one egg with 'n' set of chromosomes meets the required condition for the progeny to be born.

In studying micrographs of an unusual protist that you found in a sample of pond water, you spot an organelle that you can't recognize. You successfully develop a method for growing this organism in a liquid in the laboratory. Describe ow you would go about finding out what this organelle is and what it does in the cells. Assume that you would make use of additional microscopy, cell fractionation, and biochemical tests.
