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.
Answer:
Option C (very coarse texture) is the appropriate one.
Explanation:
- Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively.
- We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.
Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
The independent variable is the variable that is being changed in an experiment. It is also called the manipulated variable. In this case, it would be the amount of sunlight. The dependent variable would be the variable that is being studied. In this case it would be the length of sleep of the mice. The constants would be the variable that are supposed to have an effect on the dependent variable however it is held constant so as to clearly see the effect of the independent variable.
Answer:
Correct option is D.
Explanation:
Our nervous system contain cells which are known as neurons these cells help to send information from the spinal cord, and brain. From receptors sensory nervous receive stimuli, and then help in to transfer this information from cell to cell in the central nervous system.
These cells work by change in voltage potential which is present in plasma membrane. So, after the first channel opens, the movement of many types of ions (both inside and outside the cell) alters the distribution of charges near the second channel, causing it to open.
