<span>The hypothalamus is the </span>area of the brain that responds to an increased concentration of blood electrolytes and initiates drinking behavior.
The hypothalamus contains a number of small nuclei with a variety of functions.<span>It coordinates automatic brain functions and hormone release. Alcohol depresses nerve centers in the hypothalamus that control sexual arousal and performance. </span>
<span>B is the correct answer. The beginning of DNA replication occurs with the unwinding of the DNA helix by a special enzyme. The two strands that form the helix then create a replication fork. The two strands are then oriented differently, one becoming the 'leading strand' and one the 'lagging strand'. </span>
The surface area to volume ratio of the cell decreases.
This decrease is due to the fact that the volume of the cell increases at a greater rate than the surface surrounding the cell, the cell membrane, increases. This change is also visible when we are blowing up a balloon.
When considering the cell division, the ratio remains roughly the same. It is advantageous for the cell to preserve its surface area to volume ratio, since a higher ratio means that substances are able to diffuse into and out of the cell at a fairly higher rate.
Angiosperms are commonly referred to as flowering plants, which have the highest division in Kingdom Plantae.
<h3>What are the characteristics of the Angiosperms?</h3>
- Angiosperms are flowering plants, which are characterized by the production of colorful flowers and fruits.
- Angiosperms undergo syngenesis, in which the ovary is converted to fruit and the ovule is converted into the seeds.
- Angiosperms are highly developed and vascular plants, which consist of xylem, phloem, and other specialized tissues.
- The angiosperms have developed root and stem systems. Stem provides adherence and support, while roots help in the absorption of nutrients from the soil.
Thus, angiosperms have the highest rank of division in the kingdom Plantae and bear several characteristic features like flowers, fruits, and roots.
