To prevent cells from either shrinking or swelling you should keep them in an isotonic solution. Isotonic solution is a solution with equal amount of solute and solvent. Therefore, when cells are placed in such a solution they will not lose or gain water, as opposed to hypertonic (more solute than solvent) and hypotonic (more solvent than solute) solutions.
Explanation:
Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 65million years a couple of things can happen:
- Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.
- The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.
- Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
All these factors will eventually have a prolonged effect that combine to force dinosaurs into extinction.

The answer is fertilization.
Fertilization is the process in which two gametes fuse which
first creates a zygote and then leads to the development of an embryo. Pollination is a transfer of male pollen to the female reproductive organ. By reaching there, male gamete and female gamete will fuse which represents fertilization. So, pollination is <span>an important step in the fertilization of flowering plants.</span>
