The correct answer is 2. By a feedback loop.
Hormone levels in the body is regulated by negative feedback mechanism. In this mechanism, a stimulus stimulates the release of a substances. After the effect of that substance its further release is inhibited. This can be understood by an example, the anterior pituitary gland stimulate the thyroid gland to release thyroxin and on increasing the thyroxin in the blood, feedback the hypothalamus and anterior pituitary to inhibit further release of thyroxin from thyroid gland.
Answer:
B.chickens are more closely related to ducks than they are to humans.
Explanation:
Amino acids are coded for by codons.
Codons are sequence of nucleotide bases from mRNA.
mRNA are synthesized using DNA templates.
Therefore, the more similar the amino acid sequence of two organisms, the more genetically related the organisms are.
<em>Chickens and ducks had amino acid sequence of 3 while chickens and humans had 13. It thus means that chickens and ducks are more related as compared to chickens and humans.</em>
The correct option is B.
Answer:
it occurs in organism who undergoes asexual reproduction
Explanation:
Not all organisms that undergo Asexual reproduction undergoes mitosis and meiosis
yeast undergoes budding
hydra also undergoes budding
but amoeba and paramecium undergoes mitosis or meiosis
Answer:
correct option is E) horizontal gene transfer
Explanation:
solution
we know here that phenomenon account for movement of these genes is horizontal gene transfer because we know Horizontal gene transfer are primary mechanism for spreading of antibiotic resistance in the bacteria
and
in many mechanism some are
(1) transformation
(2) transduction
(3) Gene transfer agents
and that Gene transfer agent is virus and it like element encode by host that is occur in alpha proteobacteria
and
we know that implant of one to other plant can transfer chloroplasts , mitochondrial and entire cell nucleus contain the genome to the potential makes new species
as that we can say here correct option is E) horizontal gene transfer
Answer Explanation:
Due to technical difficulties, the answer and explanation for this problem are available in the attached file.
