Polychaeta generally refers to a class of annelid worms with segmented body parts.
Even though all of the answers are annelid worms, polychaetes are generally marine animals, so I would say that the answer is most likely Clam Worms.
Answer:
It is homozygous at two gene loci.
Explanation:
An organism may be homozygous or heterozygous for a particular gene. The presence of two identical alleles of a gene in the genome of an organism makes it homozygous for the gene. On the other hand, the presence of two dissimilar alleles of a gene makes the organism heterozygous for the gene.
For instance, AA or aa are homozygous states since two copies of identical alleles (dominant and recessive respectively) are present. The genotype "Aa" is heterozygous since it has one dominant and one recessive allele for a particular gene.
The given genotype "AABbcc" is homozygous for "A" and "c" due to the presence of two copies of dominant and recessive alleles respectively. However, it is heterozygous for the second loci (Bb). Since the recessive allele is present in the homozygous state (cc), it will express itself.
Answer:
The correct option is A) the hypothalamus
Explanation:
The hypothalamus is a part of the diencephalon located below the thalamus and formed by several nuclei of neurons with their associated nerve fibers, many of them neurosecretory nature, that is, to the hypothalamus, afferent and efferent pathways arrive and depart respectively, which connect it with different regions of the brain and outside it, receives signals from internal sensory receptors and, in response, sends orders through pathways in which very few synapses intervene to quickly generate regulatory responses, for this reason, the hypothalamus is considered the center of neuroendocrine, autonomous and homeostatic regulation, which acts as an integrating center coordinating environmental messages, rhythms, endogenous development patterns, emotions and body signals, to finally produce, in an integrated way, early autonomous responses and relatively late endocrine responses.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)
Answer:
The answer would be search for mutations with large deletions.
Explanation:
The reason why is becasuse what Polymerase Chain Reaction (PCR) does is amplify specific regions of DNA. PCR often is used to test for viruses like SARS-CoV-2 along with other infectious diseases.
Hope this helps.
