Biology

Kobotan [32]3 years ago
8 0

Explanation:

A hydrogen bond is a common type of chemical bond in organisms. As the name suggests, this type of bond involves a hydrogen atom. The hydrogen is attracted to a strongly electronegative atom, such as oxygen, fluorine, or nitrogen of a polar covalent bond in the same or another molecule.

This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

<h3>What is irrigation?</h3>

Irrigation is a technology based on the artificial supply of water to recover crops from drought conditions.

Genetic modification may also help with drought conditions by inserting into the genome of the target species gene sequences associated with hydric stress (e.g., a protein channel to close stomata at night).

In conclusion, irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

erik [133]
<h3><u>Answer;</u></h3>

It occurs over many generations.

It happens at the genetic level.

<h3><u>Explanation</u>;</h3>
  • <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
  • <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
  • <em><u>Therefore, evolution will only occur when there is change in gene frequency within a population over a given period of time. Genetic differences that are heritable are passed to the next generation.</u></em>
