Nuetrik [128]3 years ago
4 0

Answer:

The rate of activity of an enzyme might change as pH changes

Explanation:

Enzymes are organic catalysts that controls the rate of a specific chemical reaction.

These materials combines substrates in order to lower the activation energy which might serves as a barrier to chemical action.

  • Enzymes have specific reactions which they control.
  • Temperature and PH conditions control the rate at which enzymes work.
  • They are not all produced from the building block of carbohydrates.

Which term specifically describes the categorization of people into ethnic groups without taking into account individual differe
zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.

If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

Answer:

Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.

Explanation:

In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.

These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.

These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations

It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.

What is actually cycled in a web of organisms?
KengaRu [80]

Answer:

Carbondioxide gas.

Explanation:

Carbondioxide gas is actually cycled in a web of organisms, The plants takes carbondioxide gas for the process of photosynthesis, this plant is eaten by herbivores for energy and carbondioxide is released in the process of respiration. After that, carnivores feed on these herbivores and oxygen is used in the breakdown of food for releasing energy and carbondioxide gas is also released from the body through breathing so the cycle of carbondioxide gas is continue.
