Answer:
D
Explanation:
In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.
Answer: there would be no way for energy to enter the food web, and the ecological community would collapse.
Explanation:
everything would die because its a domino effect
Explanation:
Some diabetics neglect to take insulin doses specified for them throughout the day or follow some wrong practices that reduce its effectiveness, which causes a decline in its role in processing glucose to produce the energy needed to perform daily activities, which leads to its deposition in the bloodstream.
Answer:
Nitrogen 15, N15 isotope,
Explanation:
Generally Nitrogen has two isotopes N14 and N15. The N14 has 7 protons and 7 neutrons with the atomic mass of 28( n+p). However the N15 has 7 protons and 8 neutrons.Since Neutrons are heavier than protons and constituted greater percentage of the atomic mass of an element the N15 isotope is heavier than the N14 isotope.
Therefore, Ammonium chloride solution containing the labeled heavier N15 was initially added to the bacterial growing medium; so that the bacterial can use it to make their DNA, and divided manytimes so that N15 isotopes is fully incorporated Therefore the DNA strands which incorporated this will be heavier,(old) and easier to segregate to the lower band during centrifugation , for identification compare to the newer lighter ones.
<u>Thus the parent( </u><u>heavy/old</u><u>) containing DNA N15 and( New/light) in the daughter DNA N14 strands can easily be separated for identification during semi- conservative replication.</u>
