Answer:
The Miller and Urey experiment is a well-known classic experiment in which hypothetical conditions of the early Earth's evolution were simulated to test the possibility of chemical evolution. In fact, this was an experimental test of the hypothesis previously expressed by Alexander Oparin and John Haldane that the conditions that existed on primitive Earth promoted chemical reactions that could lead to the synthesis of organic molecules from inorganic ones. It was held in 1953 by Stanley Miller and Harold Urey. The apparatus designed for the experiment included a mixture of gases corresponding to the notion of the composition of the atmosphere of the early Earth in the 1950s, and electric discharges passing through it (simulating lightning strikes on the ground). The Miller and Urey experiment is considered one of the most important experiments in the study of the origin of life on Earth.
We are learning about that in my cell biology class.a cytoskeleton is like your muscles because it can contract like muscles which gives the cell shape,strength,and make it divide.
Answer option:
1. duplicate themselves
2. convert energy
3. selectively exchange materials
4. all of the above
Answer:
4. all of the above
Explanation:
Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.
They can convert glucose into cellular energy (ATP) through respiration in the mitochondria
They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.
Therefore, all of the above is correct.
