Answer:

Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.

Explanation:

The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!

The goal of all atoms on found on the Periodic Table is to become stable.<br> True<br> False
inysia [295]

Answer:

True

Explanation:

An atom is stable because of a balanced nucleus that does not contain surplus energy. If the forces between the protons and the neutrons in the nucleus are unbalanced, then the atom is unstable. Stable atoms retain their form for ever, while unstable atoms undergo radioactive decay.

Suppose the fictional condition lycanthropy is an autosomal dominant disorder that causes an affected person to have a strong ph
hodyreva [135]

Answer:

Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.  

Explanation:

As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.

In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.

The long nephron loops of the ____ nephrons are located in the renal ___
igor_vitrenko [27]

The long nephron loops of the juxtamedullary nephrons are located in the renal medulla.

<u>Explanation:</u>

The kidneys are the major filtering units that are present in the body. The kidneys filter the ions of the body and expel the waste of the body and retain the required ions in the body.

The nephrons are the functional units of the kidney that are majorly responsible for the filtering action. The longer the nephron loops are more concentrated urine is expelled from the body.
