Answer: A vacuole undergoes a change in the plant causing wilting and droping.
Explanation:
The vacuole is an organelle, which is a store house of excess water and stored materials. During dehydration, the plant uses water from vacuole. Thus water and stored materials reservoirs get consumed up in this process, the plant experiences scarcity of water. This causes wilting and droping of plant.
The cell membrane is an envelop outside the cells, which causes plants to maintain their structure during stress for example, plant exposed to hypertonic solution. This prevents the cells to burst.
A virus require a living host. A host can be a plant, animal, human, or any other living organism. It does not have a cellular machinery thus uses host cell machinery to replicate its genetic material and produce its progeny.
Answer:
Explanation: Despite the affluence, there is still inequity. Increasing and deliberate inequity at that, for it is a necessary feature of a growth economy and the driver of material self-advancement. Desirable though high standards of living may be, there are finite global limits.
All of the above is the answer
Answer:
Raising the temperature from 20c to body temperature
Explanation:
The increase in temperature will give the particles more thermo energy therefore it will increase the rate of an enzyme-controlled reaction
Answer:
DNA replication is initiated by the help of these enzymes.
Explanation:
Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.
Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.
Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.
