Yes, enzyme activity can be influenced by natural selection. Enzymes that confer a fitness advantage to an organism by improving its ability to survive and reproduce are more likely to be passed on to future generations. Over time, this can lead to the accumulation of specific enzyme variants that are better suited to the organism's environment.
Mutation is not a way in which natural selection affects the distributions of phenotypes. Mutations introduce new genetic variations, which can then be acted upon by natural selection to influence the distribution of phenotypes within a population.
fit into the active site on the enzyme
The individual or his/her (assuming a sexed species) genes. Still a bit of a ' bone of contention in biology between these two levels; the gene and the individual. The only truly marginalized position as to ' target ' of selection is the group.
The substrate is the molecule that the enzyme acts upon, fitting into the enzyme's active site like a key fitting into a lock. This binding triggers a conformational change in the enzyme that allows it to catalyze the reaction more efficiently. The substrate provides the specific chemical groups and orientation needed for the enzyme to perform its function.
D. substrate (a specific reactant acted upon by an enzyme is called the enzyme's substrate.)
Yes.
all i know is that its False

A substrate is the substance acted upon by an enzyme. The enzyme substrate complex is when an enzyme molecule combines with its substrates.
The chemical reactions occur on the active site of an enzyme. The rest of the answers could include "substrate" for the molecule acted upon by the enzyme, "cofactor" for an additional substance required for enzyme activity, and "inhibitor" for a molecule that reduces enzyme activity.
Traits controlled by genes are subject to natural selection because they are heritable and can be passed on to offspring, allowing successful variations to increase in frequency over generations. Traits that are not controlled by genes, such as behavior or learned characteristics, are not directly influenced by genetic inheritance and therefore cannot be directly acted upon by natural selection.
because there are alot of peters iin the world like obama
False substrates are molecules that resemble the natural substrate of an enzyme but cannot be acted upon by the enzyme. They compete with the actual substrate for the enzyme's active site, inhibiting the enzyme's normal function. This can lead to a decrease in enzyme activity and disrupt biochemical pathways.
Selection and Environmental change
This is known as an enzymatic reaction.
Genetic variation that can be acted on by environmental pressure. Reproductive population that results in more organisms than can be supported by the ecosystem resulting in competition for limited resources, the ability of the organism to transmit genetic information to the next generation.
One common test to detect the presence of an enzyme in a biological washing powder is to perform an enzyme activity test. This can be done by measuring the rate of reaction or the products formed when the enzyme acts on its substrate. Another method is to use specific substrates that change color when acted upon by the enzyme, indicating its presence.
