Answer:
Lymph nodes swell to protect us from illness if they do not swell non fatal illnesses could spell out death
Explanation:
Answer:
The changing variables are: v and KE
Explanation:
Given
Required: What changes?
From the formula above:
m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater.
KE: When velocity changes, the kinetic energy also changes
So:
The changing variables are: v and KE
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction between the air and the swing and between the chains and the attachment points slows it down and eventually stops it.
The answer is B, osmosis is the movement of water. Diffusion is the movement to chemicals and molecules.
Both osmosis and diffusion are movement of molecules from a region of higher concentration of the substance moving to lower concentration down the concentration gradient. However, osmosis is only for the movement of water molecules, while diffusion is for any type of substances including liquid or gas. So we can also say osmosis is a type of diffusion actually.
And also, both of these movement of molecules does not require extra energy, they all happen due to natural tendency.
Division is basically a mathematical function that can be used to take parts of other numbers.
In division, there are two main things you have to remember, the dividend, or the number that is being divided into some part. The part is also called the divisor, or the number that is dividing the dividend.
Here is an example:
200 ÷ 100 => 100 is the divisor and 200 is the dividend
Here is how you solve it:
200 ÷ 100 = ?
Multiplication: what times 100 is 200? The answer is 2.
200 ÷ 100 = 2
Hope this helps and have a phenomenal day!
