The human egg cell is the largest cell in the human body, measuring approximately 0.13 mm in diameter.
Its size is 10 times the diameter and 1000 times the volume of most other human body cells. It can actually be seen without the aid of a microscope if one observes keenly.
Unlike ordinary body cells which have a cell membrane, the egg has a special outer coat called zona pellucida which is made up of a jelly-like extracellular matrix composed mainly of glycoproteins.
Answer: damage can be measured using the Richter scale
Answer: Mars receives more insolation than Saturn.
Explanation:
Insolation is defined as the exposure to the Sun's rays.
Mars is the 4th planet in Our solar system and is near to the Sun.
Saturn is the 6th-planet in Our solar system and is far from the Sun.
Insolation is directly proportional to the planet's distance from the Sun.
So, the exposure of Sun's rays is more to the planet which lie close to the Sun.
As, Mars is close to the sun than Saturn. Hence, it will receive more insolation than Saturn.
Answer:
3. A decrease in light intensity means a decrease in the energy required for photosynthesis to take place.
Explanation:
The greater the light intensity, the more energy supplied to the plant and therefore the faster the light-dependent stage of photosynthesis can occur.
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
