Physcial weathering is the process that breaks rocks apart. So, I suppose when an earthworms digs and tunnels their way through the soil? They move the broken peices of rock causing it to break into smaller peices.

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? A.

iren [92.7K]

The answer is C.silent.

Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.

Which pharmacokinetic parameter is affected most by decreased intestinal motility related to the aging process? a. excretion b.

Tpy6a [65]

I believe the answer is c. absorption

The phase of pharmacokinetic that happens in the intestine is when the drug absorbed. A person with old age will have lower intestine motility. This will increase the transit time which will increase the amount of drug absorbed.

Age could also influence others pharmacokinetic parameter(excretion, distribution, metabolism) but it is related with another organ, not intestine.
