Answer:

<h2>(A) Protein x normally stimulates cell division.</h2><h2 />

Explanation:

Protein who stimulates cell division are known as proto-oncogenes. If there is a mutation in proto-oncogene ,then this gene is converted into oncogene which causes cancer. Here protein x ( proto-oncogenes) normally stimulates cell division, if new mutation occurs in this gene, then this gene is converted into oncogene and resulted in the formation of cancer.

What path does pollen need to travel for the plant to reproduce?.
FrozenT [24]

Answer:

stigma

Explanation:

Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.

Biodiversity Aa Aa Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined
sattari [20]

Answer:

Based on the first study it is evident that the ecologists are looking for functional diversity as they are making a note of different functions performed by a distinct kind of species found on different plots.  

On the other hand, based on the second study it is evident that the ecologists are studying the species diversity as with the assistance of different wavelengths of light reflected by the vegetation, they are differentiating between the vegetation found in different parts of the continent.  

The biodiversity helps humans in different ways, that is, by supporting the society in which they live and by maintaining a healthy biosphere. The biodiversity found around helps in the procedure of dead species decomposition, they offer humans with nutritious food, and also acts as natural sieves and clean the water for consumption. Hence, the correct options are 1, 2, and 3.

Do you think one reproductive process promotes higher genetic variation than the other?
Alina [70]
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
