Answer:
1. Support
2. Protection
3. Movement
4. Supply & Storage
Explanation:
1. Support : It provides a framework to support the organs and tissues of the body.
2. Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).
3. Movement: It provides a framework for muscles to attach. Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.
4. Supply & Storage: The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
A. arteries and veins.
Just as tubes within the stems and leaves of plants transport water, arteries and veins within animals transport blood with the required nutrients for our bodies.
The plant cells are more complex because it has more structures like the cell wall and chloroplast.
Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Hope this helps.
The
answer is c. shear
When earthquakes occurs, rocks are constantly exposed to forces
known as stress which cause deformation of rocks that tend to bend, twist, or
fracture them. The respond to stress that result to changes in shape, size, or
volume are referred to as strain.

If stress act
equally from all directions, the applied force is a uniform stress. However,
if stress is not equivalent from all directions then it is a
differential stress. Moreover, there are various kinds of differential stress namely,
tensional stress that causes the rock to stretch, the compressional stress
that squeezes the rock and the shear stress which is a consequence of
slippage, twisting or transformation of rocks.
