Answer:
The answer is 6.4 × Joules
Explanation:
This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:
Force = 8.0 pN = 8.0 × N
displacement = 8.0 nm = 8.0 × N
Now let us calculate the work.
work = Force × Displacement
work = 8.0 × × 8.0 × = 64 ×
= 6.4 × Joules (in standard form)
Answer:
They will collapse and shut off the stomatal pore
Explanation:
The guard cells are regulated by the presence of water. When water is present, they become turgid and open up the stomatal pore and when water is inadequate, they become flaccid, collapse and close up the stomatal pore as a result.
<em>If the leaf is left under the microscope for too long, there will be loss of water by evapotranspiration and the guard cell will become flaccid and collapse as a result and the stomatal pore will become closed.</em>
Answer:
Selection may be defined as the process of selecting the more favorable species than the less favored one and can adapt in the environment. The selection increase the chances of survival of the organism.
The genetic variation hidden means the variation is not visible in the population and present in the form of heterozygotes in the population. This genetic variation can be expressed by the recombination of the heterozygotes in the population.
Answer:
O Bioenergy does not release harmful greenhouse gasses.
Explanation:
Nuclear energy might not releases as much greenhouse gasses as fossil fuels do but it still releases some. Bioenergy produces energy by using 100% natural elements whereas nuclear energy does not.
