chromosomes?
A. histones
B. RNA
C. lipid
what is the function of each stage of meiosis?
Answer:
Before the cell enters meiosis, the chromosomes in a cell are duplicated (during the interphase). In meiosis I, the chromosomes condense along the center of the nucleus and pair with their homologues during crossing over. Next, the pairs of chromosomes separate and move to opposite ends of the cell.

B. the oceans.
C. the atmosphere.
D. nucleic acids.
Compare between red blood cells and white blood cells
And write both
Answer:
The main difference between red blood cells and white blood cells is their function; red blood transport oxygen throughout the body while white blood cells are involved in the defense of the animals, destroying pathogens which invade the body cells.

how can a rare trait be dominant
Answer:Just because a gene is dominant, and it takes just one translated allele for the trait to appear, doesn't necessarily mean that it's a physical trait that you'll see frequently in the population. Some dominant genes are rare, meaning that a small subset of humans have the dominant allele.

Which of the follwing functions at the same organizational level as the skin in the human integumentary system?
The human integumentary system in body helps regulate body temperature through its compact association with the sympathetic nervous system (SNP), the division of the nervous system involved in our fight-or-flight responses. Hair can be curly, strait, or wavy, it can also be rough, smooth or silky. But the main function of the hair is to cover or insulate our body. It helps regulate body temperature. It also diverge a person's sweat or perspire.
What is sympathetic nervous system?The sympathetic nervous system is constant monitoring body temperature and start appropriate motor responses.
For example, the sweat glands, accessory structures of the skin, release water, salt, and other substances to cool down the body when it becomes warm.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
