Answer:
2 cells meet and the number of chromosomes becomes equivalent to the somatic cell.
Explanation:
In meiosis crossing over occurs and the number of chromosomes divided or remain half as compared to a somatic cell which is called Haploid (n). When two haploid cell meets than diploid (2n) cell formed which further transforms into a zygote. So, the purpose of meiosis is the cross over which creates genetic variation among individuals and reduced the number of chromosomes into the half. Because if the number of chromosomes remains the same as (2n) and (2n) meets and becomes 4n. Which is the wrong pattern so nature keeps this balance in a unique manner that (n) and (n) meets and form (2n).
Answer:
This element is carbon.
Explanation:
You might be quick to think the answer is something like hydrogen and oxygen because both form to make water. But understand that the question is not asking about important elements in life, just which element makes up organic molecules. This element happens to be carbon.
It's important to understand that carbon is lucky in that it has 4 valence electrons and is able to bond with other important elements, like F, N, and especially H. The bond between C-H is essential in organic chemistry because it represents the structure of an organic molecule and helps with the IUPAC naming of organic molecules. It also suffices to say that there is a cycle for carbon in the carbon cycle, which transports carbon from one place in our world to the other.
So, it suffices to say that carbon is in fact essential for making up organic molecules.
Answer:
Idea models represent the premise of the idea, but the model is just that, it's a simpler form of the idea.
In reality idea can vary on how complex or simple they can be and models are usually made to represent ideas that are too complex to just make or say.
Answer:
A compound, water is a liquid.
Explanation:
When elements combine (2 of them), they are called a compound.
