Answer:

Option B

Explanation:

An economics footprint can be described as a measure of biological productivity.

Ecological footprints show a comparison of the rapidness of our resources consumption and waste generation to the rapidness of natural absorbing these wastes and also including our carbon emission.

Thus, one of the characteristics of ecological footprints is a measure of our biological productivity.

Answer:

c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.

Explanation:

Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.

polet [3.4K]

Answer:

C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.

Explanation:

A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.

Answer:

A control variable is the variable in the experiment that does not change.

Explanation:

If you are testing how seeds grow in different types of water, and you add 1tbps of salt to one pot of water with the plant, and then added 2tbps to another pot of water with the plant. The control variable in this experiment would be the water with no salt because it was not altered.

FYI I did not pull from google. Good luck!
