13. Which process requires cellular energy?

Biology
1 answer:
Aleks04 [339]3 years ago
3 0

Answer:

Some such means, like diffusion and osmosis, are natural processes that require no expenditure of energy from the cell and are called passive transport. Other methods of transport do require cellular energy and are called active transport.

Help!! I'm doing a lab report and am unsure which variables are independent, dependent, and controlled. My lab is due tomorrow
victus00 [196]

Im not sure but if you think of it, the one that you didn't put any salt is a independent  variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !

What causes genetic variation in a population
Gre4nikov [31]

Answer:

A lot of factors cause genetic variation in a population. The root of all genetic variation is mutations, which occur randomly.

A lot of genetic variation in fact results during meiosis, the process by which gametes (sex/reproductive cells) are formed. The 3 main ways are crossing over, independent assortment of chromosomes, and random fertilization. Crossing over occurs during Prophase I of meiosis, in which genetic material is exchanged between nonsister chromatids of homologous chromosomes. Independent assortment refers to the following: When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other.  Random fertilization is where any sperm can fertilize any egg cell. The many combinations of eggs and sperms mean variation.

Another source of genetic variation include gene flow. Gene flow is where populations have their members enter other populations (migration), influencing the gene pool of populations. This source is more controversial, however.

Random mating can also increase genetic variation.

How does an animal’s level of fitness relate to its chances of survival and reproduction?
Mademuasel [1]
An animal that is healthier will have a better chance of survival due to better strength, and also be better suited to winning a mate. Animals that are weak or sick are most likely to die off or be killed by a predator or natural reasons, if this animal survives, it will most likely not get a mate because the mate will not be attracted to the sickened animal, considering how most animals search for a healthy mate to reproduce with. (Usually there is some type of court ship dance or song of some sort, and it is usually the more healthy animal that is able to "perform" the best dance/song for the mate it is trying to win over) Hope that this helped!
