why do cells need to regulate what goes in and out of them?

Answers

Answer 1
my Answer:

These molecules are essential for living things. The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through

Mendel crossed pea plants dominant for two different traits (tall and green pods) with pea plants recessive for those same two traits (short and yellow pods). This cross resulted in pea plants that had combinations of all four traits (tall with green pods, tall with yellow pods, short with green pods, and short with yellow pods). Which law of inheritance best describes why this happens

Answers

The law of inheritance that explains such a pattern of trait inheritance is the law of independent assortment of genes.

Law of independent assortment

The law states that characters are inherited independently from one another. In other words, the inheritance of trait 1 is totally independent of the inheritance of trait 2.

There are several exemptions to the law of independent assortment of genes. There have been cases of linkages and gene interactions such as pleiotropy.

Why do baby bones contain more cartilage than an adult's?

Answers

Babies are less bony for a good reason; if they were fully “hardened”, it would make delivery almost impossible. Infants’ bodies need to be extremely soft and limber so that they can be born in the first place! Babies are born with more cartilage (than bone), but it gradually turns into bone over a period of time through a process called endochondral ossification. This is a vital part of the developmental stages of a fetus and leads to the creation of bone tissue in the body. As the baby grows, cartilage is replaced by bone matrices. Calcium salts (that babies get from their diet) are laid to form hardened bones. This is the reason why adults have fewer bones than babies because, for babies, many small bony segments fuse together to form a single bone.

Answer:

distribute body weight over a large area

Explanation:

This one's fairly simple. If you have large feet, then your body weight is distributed over a large area (you don't sink as much in sand). If your toes were small, massive body weight would sink the feet into sand.

Which of the following phases ends just before cell division?
A. M phase
B. G1 phase
C. G2 phase

Answers

Answer:

C

Explanation:

The G2 phase ends just before cell division as it is considered as the last phase of the process of cell division. Thus, option C is correct.

What happens in different phase of cell cycle?

In eukaryotic cells, the phases of the cell cycle are divided into two major phases, which are interphase and mitotic stage. During the mitotic stage, cell divides its DNA and cytoplasm into two equal parts, thereby forming two daughter cells.

Cell division is essential for organism growth, tissue repair, healing and regeneration, and reproduction. The process by which a parent cell divides into daughter cells is known as cell division. For both single-cell and multicellular organisms, cell division is essential. Cell division can directly increase the population of single-celled organisms like Amoeba or Paramecium.

Therefore, The G2 phase ends just before cell division as it is considered as the last phase of the process of cell division. Thus, option C is correct.

What happens to the distance between molecules when a substance changes from a liquid to a gas? Why?

Answers

When a substance changes from a liquid to a gas, the distance between molecules increases.

The distance between molecules increase because vaporization occurs. During the process of vaporization, the liquid molecules acquire higher kinetic energy, which means they move more quickly and freely through the substance.
