Answer:
DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.
Enzymes are biological catalysts. ... Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate.on:
Answer:
magma, geothermal heat, and friction
Explanation:
Magma, geothermal heat, and friction along fault lines are different forms of heat used to change rocks into metamorphic rocks.
O blood has no<span> antigens and is referred to as </span>universal donor blood<span>, so that </span>will<span> not cause a reaction. So, a </span>person<span> with </span>AB blood has<span> all of the antigens that are possible, and an O negative </span>person has no<span> antigens that would cause a reaction.</span>
