Answer:
The volume of the cell will remain same.
Explanation:
The cell is surrounded by a solution that has same concentration of solute particles as the cytosol inside.That means the cytosol of the cell is isotonic to the solution in which the cell is kept.
As a result the cell will neither swells nor shrinks and the volume of the cell remains constant.
Answer:
Explanation:
Darwin's use of many different fields of study including geology, economics, and biology was incredibly important as it allowed him to make connections between them that ultimately led to ground breaking discovery. Such as animals that that migrated to different areas and were interconnected through their geological footprints that were left behind.
Answer:
Lightly pigmented people tend to be at higher risk of vitamin D deficiency
Explanation:
BACKGROUND KNOWLEDGE:
Human skin is the largest organ of the body which makes boundary line between environment and internal conditions. Human skin cell produces pigment called melanin when ever it is subjected to Sun. More the melanin pigment produced more will be the skin darkens. Ultraviolet (UV) radiations also come from Sun and responsible for more pigmentation.
ANSWER EXPLANATION:
According to the question darkly pigmentation only occurs when their is high level of UV radiations. High level of UV radiations are also responsible for Vitamin D production.
People with lightly pigmented means that there environment has low level of UV radiations which are the requirement of Vitamin D production. Hence due to low UV radiations peoples with light pigmentation's are also be at higher risk of vitamin D deficiency
Isotonic solution
This is a solution in which there is no net movement of water into our out of the cell when a cell is placed in this solution. The solution is also dilute.
