Biology
1 answer:
quester [9]3 years ago
3 0

Answer:

Mutations are naturally caused by errors in DNA replication, by physical or chemical methods. The mutations change the genetic makeup of the organism and introduce new alleles or combination of alleles in a population. These random mutations accumulate over time and increase the genetic variation among the population.

Answer:

Trunk flexor endurance test.

Explanation:

McGill’s torso muscular test is generally used to assess the muscle endurance of the torso muscles that works as a stabilizer. This test generally includes the four major test.

The test that includes the trunk flexor of the endurance test is a timed test that involves the static isometric contraction of the muscles. This test stabilizes the spine til the individual cannot hold the assumed position and the individual exhibits the fatigue.

Approximately 21% of the human genome is comprised of nucleotides containing C. Given this information, calculate the percentage
azamat

Answer:

(a) 21% of the human genome is comprised of G.

(b) 29% of the human genome is comprised of T.

(c) 29% of the human genome is comprised of A.

Explanation:

According to Chargaff's rule, a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G), and G pairs with C and A pairs with T.

If 21% of the genome contains C, then 21% also contains G.

Therefore 21% + 21% = 42% of the genome is comprised of G+C.

The other 58% is comprised of A+T, and because they pair with each other, 29% will correspond to A and 29% will correspond to T,

Urgently! <br> Give reasons <br> Fruits vegetables and grains should be washed thoroughly
-BARSIC- [3]

“It is not always possible to find or buy organic fruits and vegetables in today's conditions. In order to purify pesticide residues in foods, the first thing that is usually done at home is to put these foods in vinegar water. However, vinegar water is not effective in reducing pesticide residues, but in reducing the microorganism burden. Studies have done that vinegar water increases the effectiveness of pesticide residues even more. The main purpose of adding vinegar to the washing water is to create an acidic washing environment and to remove the potentially harmful biological factors that can be found on the food in case of inadequate washing. However, many of the pesticides commonly used today cannot be removed from the food due to insufficient washing and are taken into thBe body. This causes pesticides to continue their harmful effects for long periods of time.
