“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.
Answer:
D.) Gene Flow
Explanation: In a population genetics, gene flow (also known as gene migration or allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.
Oxygen, carbon, and hydrogen
Uhh no offense but this question makes no sense (to me any ways)
Answer:
changes in the environment could influence gene expression.
Explanation:
In humans, <u>skin color is defined by the abundance of "melanin" pigment</u>. The <u>darker is skin</u>, <u>high pigmentation</u> is there. Studies have proven that <u>high temperature</u> is the major reason for <u>high pigmentation/darker skin</u>. This is due to the reason that <u>high temperature</u> leads to the <u>increased expression</u> of the specific pigmentation related <u>genes</u> (e.g. MC1R gene). So, if a human is exposed to high temperature for a longer period, the action (expression) of the MC1R gene will be high as well. This will result in a tanned skin color. This is the reason that those <u>humans who live near to the equator (warmer climate) </u>have <u>darker skin</u> whereas those <u>humans that live close to poles (cold climate) </u>have <u>light-colored skin</u>.
