Answer:
b. a single temporal fenestra
Explanation:
Synapsids have a temporary fossa in the lower part of the temporal bone. These reptiles mamiferoides only have a single inferior temporal fenestra.
The synapsids were the first amniots to diversify and appeared in the middle of the Carboniferous. These first synapses were characterized by the presence of a single temporary fenestra behind each orbit, through which the mandibular muscles pass.
A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

Answer:
A
Explanation:
A because water is a essential resource to humans and all types of life.
The correct answers are:
• transcribe RNA that combines with a protein that has a DNA-cleaving function.
• identify viral DNA by complementary base pairing with template DNA.
CRISPR is a DNA sequence found in bacteria (or other prokaryotic cell), derived from DNA fragments from viruses that have previously infected that bacteria. Bacteria use CRISPR to destroy DNA from next similar viruses. So, it is form of antiviral defense in bacteria.
Cas9 is an RNA-guided DNA endonuclease enzyme (DNA-cleaving function) associated with the CRISPR that cleave specific sequences of DNA complementary to the CRISPR sequence.
Answer:
endocytosis
Explanation:
It is the process of capturing a substance from outside the cell.
