Answer:
Because photosynthesis is a source of oxygen, it seems intuitive that photosynthesis evolved first: once enough O2 was in the air, then respiration would be able to arise in the newly oxygen-enriched atmosphere. However, some biologists have argued since the 1970's that respiration in fact evolved first.
You may talk about this picture:
A: it is an
ionic bond (which is a strong interaction, between two close atoms which has a large difference in their charges, like azote and oxygen)
B: is a
hydrogen bond (between O in a side and H in the other side)
C: it could be a
Van der Waals bond (small interaction between Carbon and hydrogen from different sides (London interaction))
D:
Hydrogen bond (between the Oxygen and hydrogen from different sides)
E: it's an
ionic bond
Answer:
I looked for a picture of what you were talking about and I think I found the answer
Explanation:
If this is the picture then I think its the first choice
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.

Carbohydrates, lipids, and protein have potential energy, and can be used in aerobic respiration to generate .
Carbohydrate- A carbohydrate is a naturally occurring substance or a derivative of one, made composed of molecules of carbon, hydrogen, and oxygen. The most prevalent organic compound is a carbohydrate, and all life depends on them.
Lipids- Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water.
Protein- Large, intricate molecules known as proteins serve a variety of vital functions in the body. They are crucial for the construction, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.
