<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.

3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>
Answer:
The correct answer is - DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Explanation:
The chromatin reticulum is present in the undivided cells, which condenses to form a rod-like form called a chromosome. The chromosome consists of DNA structures.
That DNA is a double helical structure and acidic in nature and it is present inside the chromosomes as it is coiled around histone protein which is basic in nature. That allows the DNA to fits in the nucleus.
Thus, the 3rd statement is the correct answer.
Answer:
Pollution.
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
Explanation:
Lentic environment is a stationary or still water, i.e water that doesn't flow but it is stationary at one place. Examples are ponds, ditches, reservoirs, lakes , pool, seep.
The major challenges of lentic environment are;
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
The density of ice does not affect its melting rate because there is more to melt in the same size but adding objects will affect the melting rates because there is less to melt
