How do the basic principles of inheritance, identified by Mendel in plants, differ from those in humans?
vlada-n [284]

Answer:

The Mendelian principles of inheritance ARE APPLIED IN HUMANS. Both plants and animalls posseses two alleles (forms) of each gene, and are inherited in Mendelian ways. Some genetic diseases are Mendelian diseases and are inherited according to Mendel laws, those are the diseases caused BY A SINGLE GENE. However, there are multigenic diseases (that involves more than one gene), multifactorial diseases (which involves several genes and environmental factors), and chromosomic diseases (like 21 trisomy) and all of these does not follow the Mendel laws.

Which element is essential to making up all organic molecules?.
goldenfox [79]

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.
