Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
Explanation:
Answer:
Diffusion
Explanation:
The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.
For example:
Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.
While,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
The answers include the following:
- The maps show that northern areas should get more precipitation, regardless of emission levels.
- Southern areas will likely get less precipitation, regardless of emission levels.
- These maps to prepare for natural disasters in the Great Plains, scientists need to ask how can we protect people and property in the event of a flood or a drought.
<h3>What is Drought?</h3>
This is referred to a period in which there is shortage of water due to reduced rainfall.
This leads to decrease in food production and the map patterns will help protect the people.
