f. low
Explanation:
Resorption is the loss of substance from any mineralized tissue, mediated by cellular and humoral systems of their own. The four mineralized tissues of our economy, bone, cement, dentin (mineralized fraction of the dentino-pulp functional complex) and enamel, offer different degrees of resistance to resorption. The bone has the greatest lability and the enamel the least. The fact that the bone tissue is the least resistant to resorption is used to move and reposition teeth by controlled forces (orthodontics); and the fact that the enamel is the most resistant has led to think that it does not suffer from resorption.
Osteoclasts They are the spring cells par excellence; they belong to the lineage of the monocitomacrophages. They are large, multinucleated mobile cells, with a clear area and a rough brush border that live for about two weeks and disappear by apoptosis (cell death programmed by fragmentation in membrane particles that allows their phagocytosis without inflammation). They are responsible for the destruction of the organic and inorganic parts of the mineralized bone fraction. They are active both in the processes of the physiological renewal of the bone and in those of its pathological loss.
<span>The interactions
between the mRNA codons and the tRNA anticodons
codes for a specific amino acid is by, it is the job of the tRNA to
start working after the mRNA has able to have its own complementary copy. The
mRNA will undergo to the nucleus and will move out, in order to go the rrna.
The three nucleotides codes the specific amino acid of the trna. The trna and
the mrna will be matched, it will now release the amino acid in the trna that
wil form a peptide bond. When the mrna is able to be decoded to form an amino
acid, it will now have the ability to break and make proteins in different
structures.</span>
Answer:
a. In the presence of 2,4 dinitrophenol, which is soluble through the lipid membranes, the H+ gets an another route to pass through the membrane. It hampers the proton gradient potential without any generation of ATP. The gradient that was being utilized for the generation of energy is now just lost in the form of heat.
b. With the reduction in the generation of energy, the cells get devoid of ATP, and drive the electron transport chain intensely so that the collapsing proton gradient gets re-established. However, it prevents the ATP synthase by providing a different path to the proton ions and thus diminishing the H+ concentration gradient.
During the S phase in the cell cycle, the chromosomes are replicated so that there are two copies. These copies are necessary so that each daughter cell created during the M phase will have an identical copy of the DNA.
Therefore, the answer is A: The DNA must be replicated.
The chromosomes joining, cell membrane expanding, and cytoplasm separating all happen during the M phase (mitosis).
Answer:
Helminths
Explanation:
Niclosamide is an anti-helminth drug. It works by inhibiting ATP generation in the mitochondria. ATP which is a major source of energy for cellular organisms is deficient thereby hindering or stopping metabolic processes and then death. Helminths in which Niclosamide is effective against include Pin worm, Round wo,Beef tapeworm( Taenia saginata) etc. The drug is taken orally.
