Explanation:
Nucleus Cytoplasm
Contains the genetic material (DNA) Contains a thick gel-like substance
The most obvious structure in the cell Contains all organelles
Contains directions for cell regulation Mostly water
The nucleus is a large and obvious organelle in the cell and it provides instructions for the regulation of the cell's activities and it contains the genetic material (DNA). All organelles are embedded in the cytoplasm which is made up of mostly water.
B. False
A neuron uses neurotransmitters to communicate
Answer:
The importance of mitosis lies in its condition of cellular reproduction par excellence, characteristic of the vast majority of life forms that currently populate the Earth.
Explanation:
Mitosis is the cellular process by which two identical nuclei are produced in preparation for cell division. In general, mitosis is immediately followed by the equitable distribution of the cell nucleus as well as the rest of the cellular content in two daughter cells.
We all start being a cell. That is quite difficult to imagine, but it is true. And now there are about a hundred billion cells in each of our bodies, and each one has to carry the complete set of DNA instructions. That means that when cells divide, all that has to be copied by some process. And that is mitosis, where each chromosome has to be converted into a pair, and then they have to separate properly so that each of the daughter cells receives a complete set.
the answer is definitely C
Hi
It is true that on the Galapagos islands Darwin observed tortoises with a dome and saddle shaped shells, you can see both in attached image.
Darwin observed that Galapagos Tortoises had the shells with different shapes depending on the Island they live, For example: The tortoises with saddle shaped shells were able to reach up to eat leaves of plants while the tortoises with dome shaped shells would not reach up and they would eat food from on ground sources. This made him think that the differences in tortoise shell is also a strong evidence that indicates that how tortoises have adapted themselves to better get their food as per the available resources and how they have evolved from same ancestral specie into two different species. This point also helped him in proposing the theory of evolution by natural selection.
Hope it helps!
