lord [1]

<h2>Competitive exclusion principle.</h2>

Explanation:

The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.

All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.

Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.

B. balanoides can use a wider range of resources than C. stellatus because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.

Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

The food we eat
The environment we expose the cell to
The substances that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.

Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

Meselson and Stahl's experiments proved that DNA replicates by which mode?

Irina18 [472]

Answer:

Semi-conservative

Explanation:

Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).

Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.

Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.

Guess what? they show both! (See the image for more information)
