Why are the seminal vesicles important for human reproduction?
This might help:
The seminal vesicles (Latin: glandulae vesiculosae), vesicular glands, or seminal glands, are a pair of simple tubular glands posteroinferior to the urinary bladder of some male mammals. Seminal vesicles are located within the pelvis. They secrete fluid that partly composes the semen.
They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.
I believe that the answer is:
A.
They allow the sperm to travel to the urethra to be released.
Answer:
(A). Result in different amino acids to be read due to frame shifts
Explanation:
Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.
These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.
This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.
Thus, the correct answer is option (A).
chlorine because it has 7 electrons on the outer shell
