Answer:
<em>A: Multiple genes contribute to human height</em>
Explanation:
What Mendel observed in pea plants is generally considered to be exceptions to what is obtainable in most living organisms. Instead of segregating and assorting independently, a lot phenotypic expressions are as a result of interaction of several genes on different loci (polygenic inheritance) while in some cases, multiple phenotypic expressions are controlled by a single gene.
Human height is a continuously varying character and has been studied to be controlled by multiple genes. In addition, the human height is often a result of complex interaction between genetics and the environment.
The correct answer is A.

Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
Answer:
Methane CH4 1 carbon atom : 4 hydrogen atoms
Sulfuric acid H2SO4 2 hydrogen atoms : 1 sulfur atom: 4 oxygen atoms
