Some factories drain chemicals into the local water supply. Some factories also release smoke and chemicals into the air.
Not every gene has a dominant or recessive form. Each allele in the gene pair may occasionally carry equal weight and manifest as a composite physical trait.
<h3>Why are genes so important?</h3>
The building blocks of life are genes. They include instructions for constructing particular molecules and proteins that control how the body develops and functions and enable human cells to function. Additionally, they influence how certain physical traits and attributes, like hair or eye color, are expressed.
<h3>How are genes created?</h3>
One copy is passed down to them by their mother through the egg, while the other is passed down by their father (via the sperm). The 23 chromosomes in each egg and sperm are all found in one pair. When the sperm fertilizes the egg, two copies of each chromosome and two copies of each gene are produced, resulting in the development of an embryo.

Answer:
cell walls, vacuoles, chloroplasts, centriole
Explanation:
Plant cells have cell walls, one large vacuole per cell, and chloroplasts, while animal cells will have a cell membrane only and several smaller vacuoles. Animal cells also have a centriole, which is not found in most plant cells.
<u><em>NAD+ and H+ are not the same. </em></u>
NAD+ is an electron carrier. Reactions in metabolism oxidize food molecules and transfer those electrons (along with H+) to > NAD+ which is what forms NADH. Now, NADH is the reduced form of NAD+ and NAD+ is the oxidized form of NADH.
H+ on the other hand, is a proton. It is a hydrogen atom that lost it's electrons. So when you see NADH + H+, that means that the reaction removed 2 electrons and 2 H+ from the compound.
