Answer:
It maintains the shape of the cell
It helps in cell movement
It helps in material exchange
Explanation:
Answer:
Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll.

This statement is true
Explanation:
Different substances such as growth factors and nutrients affect the mechanism of density-dependent inhibition of growth as cells become more and more numerous
A: between the hydrogen atom of one water molecule and the oxygen atom of another
Nuclear power plants use the energy originating from the splitting or uranium atoms to produce steam, which in turn drives a turbine generator.
The main problem with this form of energy production is the byproduct from the nuclear reactors known as radioactive waste. Although it is no longer efficient for the energy production, this waste is still radiating large amounts of heat and radiation. Thus, they are very hazardous as they are fatal on direct exposure and can contaminate the environment.
Due to the extremely long half-life, long term storage for this waste is extremely problematic. However, if the decay rates were much faster, then the half-life would also be much shorter. Thus, short term storage solutions could be found.
Excepting the nuclear waste and the potential accidents (which are minimized in modern plants), nuclear energy does not immediately affect the climate on earth. With short half-lives, nuclear energy would perhaps become more popular than solar or wind energy as it is more reliable and efficient.
