What does the Nucleus, cell membrane, and cytoplasm do?
Serga [27]

Answer:

The cell membrane holds the cell's internal contents from its environment.

The cell membrane is comprised of two layers of fat.

The cytoplasm is a liquid in which the various organelles of the cell are suspended.

The cytoplasm keeps organelles in place. It also allows different materials to flow from one organelle to another.

The nucleus of a cell contains genetic material. DNA, RNA and mitochondria replicate in the nucleus. The nucleus also produces and replicates proteins, and sends the proteins to other parts of the cell.

I hope this helped

In the 1800s, how did Darwin explain the origin of species?
Aleksandr [31]

In the 1800s, Darwin explains the origin of species. As species originate through adaptation by natural selection.

Answer: Species originate through adaptation by natural selection

<u>Explanation: </u>

The Origin of species through natural selection is a pioneering scientific effort of the British naturalist Charles Darwin in England. Darwin's theory is that organisms are gradually evolving through what is called "natural selection"

It is a process in which organisms change due to hereditary changes in physical or behavioural traits. Changes that allow the body to better adapt to its surroundings, help it survive and have more offspring.
