Ok here we go:
Science starts with observing which leads to hypothesis, which is tested by experiments.
The other two i am not sure of. Hope i was a help to you. One thing you can do to figure out the other two is google: "what type of science includes medicine and envirnmental science", and do the same for the other one.
The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.
<h3>What is muscle contraction?</h3>
It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.
<h3>Characteristics of muscle contraction</h3>
- In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.
- The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.
- To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.
Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.

Answer:
B) geology; theory of continental drift
Explanation:
Answer:
B
Explanation:
As there are lots of mitochondria within the diagram it is very unlikely that diffusion occurs. only active transport occurs. cells within the root do not look like the diagram shown thus the statement I and IV are true.
Animal cell structures and organelles interact as a system to maintain homeostasis by making sure each part of the system works together.
