Biology
1 answer:
elixir [45]3 years ago
7 0

Answer:

They destroy the DNA or RNA

Explanation:

Cancer drugs work by damaging the RNA or DNA. The faster the cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.

What relationship between both an abiotic and a biotic factor in a ecosystem?
likoan [24]

Answer:

Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.

B. ipsilateral

C. both

Answer:B. ipsilateral

If you stimulate the left side of the subject, the response will be only in the ipsilateral which means the stimulation will be felt in the same side of the subject which in this case is the Left side if the subject.

In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-
Alex_Xolod [135]

Answer:

1128.

Explanation:

The dominant taster phenotype is 1482.

The recessive taster phenotype = 2400 – 1482 = 918 .

Recessive phenotypes = 2400 – 1482 = 918

The recessive phenotype frequency = q² = 918 / 2400 = 0.38.

the recessive allele frequency q = √0.38 = 0.62.

The dominant allele frequency, p = 1-q = 1- 0.62 = 0.38

The heterozygous frequency =  2pq = 2 ×0.38 × 0.62 = 0.47 .

The heterozygous individual in the population = 0.47 × 2400 = 1128.

Thus, the answer is 1128.
