Answer;
Two recessive alleles are the number of alleles that a person must have to have albinism.

Explanation;
When a trait is recessive, such as albinism, an individual must have two copies of a recessive allele to express that particular trait. Recessive alleles are denoted by a lowercase letter , such as b versus B. Only individuals with a bb genotye will express a recessive trait, hence, the offspring must receive one recessive trait from each parent to exhibit the recessive trait.

Julli [10]

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The answers are as;

a) 1. NADH and 7. FADH2

b) 6. O2

c) 3. NAD+, 1. H2O, 4. ATP and 8. FAD

Oxygen is the ultimate electron acceptor, and it combines with hydrogen ions to produce H2O. This process occurs at the conclusion of the electron transport process.

ATP molecules, which are carriers of energy, would be the final outcome of the oxidative phosphorylation process.

(a) NADH and FADH2 donate electrons to the electron transport chain.

(b) O2 is the final electron acceptor.

(c)  NAD+,  H2O,  ATP, and  FAD are the final products of the electron transport chain and oxidative phosphorylation.

In facilitated diffusion, __________ proteins provide openings in the plasma membrane for substances to flow through without cha
denpristay [2]

Answer: CHANNEL PROTEINS provide openings in the plasma membrane for substances to flow through without changing structure, and CARRIER PROTEINS allow passage of substances through the plasma membrane after undergoing a subtle change in shape.

Explanation: They are described thus:

A channel protein is a protein that allows the transport of specific substances across a cell membrane.

Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.
