Answer:
Gas:
- assumes the shape and volume of its container
; particles can move past one another
- compressible
; lots of free space between particles
- flows easily
; particles can move past one another
Liquid:
- assumes the shape of the part of the container which it occupies
; particles can move/slide past one another
- not easily compressible
; little free space between particles
- flows easily
; particles can move/slide past one another
Solid:
- retains a fixed volume and shape; rigid - particles locked into place
- not easily compressible
; little free space between particles
- does not flow easily
; rigid - particles cannot move/slide past one another
Particles in a:
1. gas are well separated with no regular arrangement.
2. liquid are close together with no regular arrangement.
3. solid are tightly packed, usually in a regular pattern.
Particles in a:
1. gas vibrate and move freely at high speeds.
2.liquid vibrate, move about, and slide past each other.
3. solid vibrate (jiggle) but generally do not move from place to place
hope that this helps :)
The structural level in which the muscle produces the contraction is known as the muscle fiber.
<h3>What is a muscle fiber?</h3>
A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.
This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).
In conclusion, the structural level in which the muscle contracts is the muscle fiber.

Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
Answer:
I think there is more oxygen in the troposphere because the closer you get to earth, the more oxygen there is. The troposphere is very close to the earth, therefore, there is lots of oxygen in the troposphere.
