Which of the following is true about chromosomes?
a. more complex animals have more chromosomes
b. chromosomes are found in many places of the cell.
c. sperm and eggs have half the chromosomes as other cells.
d. some chromosomes do not have dna in them.

C) Sperm and eggs are haploid. All others are diploid.

The answer for this question is letter C. It is true that sperm and eggs have half the chromosomes as other cells.  The sperm and/or the egg cell each only has 23 chromosomes, half of the original number, so that when they join to form a zygote when fertilization occurs, the zygote will have a total of 46 chromosomes, like every cell in a human does.
The others cannot be the right answer for the following reasons:
A - The complexity of an organism dos not depend on the number of chromosomes.
B - Nucleus is the only place where you can find chromosomes.
D - DNA and other proteins makes up the chromosomes.

Im assuming this is a multiple choice answer what is the answers to chooce from?

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
