Answer: Option C.

High-energy waves like UV light or radiation physically damage the DNA

Explanation:

Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.

Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.

Why would it be important for epidemiologists, scientists who study the spread of disease, to determine patient zero?
amm1812
It's important so that they know exactly where the disease started. Knowing who patient zero is helps them to identify who that person interacted with. From there, they can determine where the disease spread to. This will aid them in stopping the disease before it spreads any further.

How does genetics effects speciation?
Svet_ta [14]

Genetics affects speciation mostly via mutation caused due to adaptation and environmental conditions.

Explanation:

  • The Speciation is defined as the evolution of a species into a distinct species. The cause of this could be several, and some of them could be environmental conditions, mutations, etc
  • Environmental conditions include isolation of the species caused by mountain rise, river, flood etc. to survive they have to evolve or get adaptations to living in those conditions
  • Mutation happens for many reasons, external factors can also cause the mutations to occur. It will also lead to speciation.

suppose a cell wishes to make a protein that has 100 amino acid. How many water molecules will be created in the making of this
slega [8]
The answer is 99.

Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.
