Why are individual chromosomes more difficult to see during interphase than during mitosis?

Answers

Answer 1
Answer: In the interphase, they are really thin, just one strand which is only a few atoms wide (very challenging for an optical microscope and not too easy for the electronic one)
Answer 2
Answer:

Answer:

This

Explanation:

Individual chromosomes are more difficult to see during interphase because they are not tightly coiled and condensed. During mitosis they are tightly coiled, making them easier to see. ... In anaphase I of mitosis, sister chromatids separate.

Hope this helps!

What is the purpose of DNA structure made of nucleotides

Answers

Answer:

DNA is made up of molecules called nucleotides.

Its unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA splits down the middle and becomes two single strands. These single strands serve as templates for building two new DNA molecules - each a replica of the original DNA molecule.

In natural ecosystems, the presence of predators lessens the effects of _________________ among the prey.. .

Answers

The answer is competition. 

Competition is an interaction between organisms. If resources, such as food, water, sunlight, territory, are limited and several species depend on these resources, then, they must compete with other species to gain the resources. So, if predators are present, this means that they will maintain the size of prey population on some optimal level. With fewer individuals in the population, there will be less competition for resources.
Therefore, In natural ecosystems, the presence of predators lessens the effects of competition among the prey.
