Answer:
C
Explanation:
Becuase fom a vaccine you are recieving antibodies by another animal or human donor.
D is unlinkely since it describes how the mother is nursing the baby, so nothing directly mentioning of the baby recieving any antibodies. The other options also talk about how the body creates its own antibodies, which isn't passive immunity.
Answer:
The correct answer will be option C.
Explanation:
ATP is the energy molecule which on hydrolysis provide energy to the cells for metabolic functions.
In vitro, the standard free energy of the ATP is -30.5 kJ/mol but its value varies in the cell as the concentration of ATP and its products like ADP, AMP and Pi are unequal in a cell. The Mg2+ in the cytosol has the ability to bind ATP and ADP, as well as the time of ATP hydrolysis, differs from cell to cell, thus influencing the concentration of ATP and its products.
Thus, option C is the correct answer.
Yes accumulation of mutation can drive aging process.
Explanation:
The molecular damage that occurs in cells and tissues for a long time due to DNA damage and epigenetic changes gets accumulated in the cell.
This leads to lowering of the homeostasis in the cell during stress conditions and eventually risks of life-threatening diseases as cancers or neurodegenerative disorders develop.
Due to mutation in the gene DNA repair mechanism also gets affected this also contributes to the ageing of cells.
The telomere of the chromosome is shortened after every mitotic division but telomerase enzyme keeps adding the DNA sequence preventing shortening aging and death of the cell. If the mutation occurs in this enzyme it will increase the ageing of cells at high rate.
1) The amount of rain an area receives
<span>2) Vegetation - Deserts have a lot of runoff because there is very few plants to protect the soil. </span>
3) The type of soil (some types of soil absorb more water than others.
4) The shape of the land.
<span>5) How people use the land. For example, a paved parking lot absorbs no water, so all the rain that falls on it becomes runoff.</span>
