Anna71 [15]2 years ago
7 0

Answer:

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Explanation:

enzymes don't change their own reaction. That's because they don't affect the free energy of reactants or the products.

What’s the difference between eukaryotic cell walls and prokaryotic cell walls?
Anton [14]

Eukaryotes have a nucleus with a membrane, larger ribosomal subunits, usually reproduce sexually, and may not have a cell wall. Prokaryotes have no membrane around the nucleus, smaller ribosomal subunits, reproduce asexually, and do have cell walls.

A man has blood type O, Rh negative. These are both recessive traits. He is married to a woman who has blood type A, Rh positive
frosja888 [35]

IAIARr is the genotype of the mother.

<h3><u>Explanation</u>:</h3>

The blood groups are the heredity characteristics of the individual which governs what antigen will be present in blood and what antibody will be present in the blood plasma.

The blood group has the genetic characteristics where A and B are dominant characters and O is the recessive character. Co Dominance is seen in case of blood grouping. Similar characteristics is seen with Rh character too where Rh positive is the dominant character and Rh negative is recessive.

The father has both the recessive characteristics. So he needs to be genetically homozygous which means that he has genetic setup of IoIo and rr.

Two child born has character of A blood group and rh positive, but the other child is A blood grouped and rh negative.

So the mother ought to be heterozygous with respect to Rh group, but she is homozygous with respect to blood group.

So her genetic setup is IAIARr.
