The correct term to fill in the blank would be cortisol. In the context of stress hormones and the brain, cortisol has a profound effect on the hippocampus, a brain structure that plays a pivotal role in memory. Cortisol is classified as a steroid hormone which is produced by the adrenal gland. It is deemed as the stress hormone as it is released as a response to stress as part of the fight or flight process. From studies, cortisol was found to have effect on the hippocampus when present in high levels. It damage and kill the cells in that area of the brain. The hippocampus is the area of the brain that is responsible for the long term memory storage. So, when this part is damage then the storage for our memories would surely be affected.

What are three costs of using wind turbines as a source of electricity?
zloy xaker [14]

There are several costs associated with using wind turbines to generate electricity.

<u>Explanation:</u>

Using wind turbines to generate electricity comes with the cost of installation of the turbines. A suitable site for installation has to be selected and windmills of the required height are installed. Cost of maintenance is another cost associated with the usage of wind turbines.

The windmills are subjected to several environmental factors like rainfall, sunlight etc. These can cause damage to the windmills. Thus a regular maintenance of the turbines is essential.

Cost of procuring appropriate land for installation of wind turbines is another associated cost. Locations apt for harnessing wind energy are limited. Moreover the windmills have to be set up across a large area to produce energy in a decent scale.

The atoms of elements sometimes become "sequestered" in the environment. which of the following is an example of this?
Marta_Voda [28]

d. carbon atoms in ocean water

Explanation:

The carbon atoms in ocean water is one of the ways through which carbon is sequestered in nature.

Sequestration of carbon implies the storage of carbon either naturally or artificially for a very long time.

Carbon sequestration cuts off carbon from the normal biogeochemical cycle and stores it in natural reservoirs for a very long duration.

  • In nature, carbon is sequestered a whole lot through biological and chemical activities.
  • Phytoplanktons are food producers. When consumed by higher organisms, their organic materials which contains carbon can become sequestered when the consumer dies and falls to the bottom of the ocean.
  • Organisms that used carbonate to manufacture their shells in the ocean also sequesters carbon.

The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright.  Animal cells are more fluid.

The central vacuole is a large region in the cell that stores nutrients and fluids.  Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
