Answer:
The correct answer will be- Option-A
Explanation:
The Theory of Island Biogeography was proposed by the MacArthur and Wilson's in 1967 which proposed that the number of species-immigration and extinction rates are determined by the size of the island and distance of the island from the mainland.
The suggestions made by them are:
1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.
2. Smaller island shows a high rate of species extinction as compared to the larger island.
Thus, option-A is the correct answer.
Blood
Blood is the transport fluid circulating in the body and is responsible for the transport of substances from one point to another. Blood is composed of red blood cells, white blood cells, platelets and plasma. All of these components work together and transport substances such as oxygen, glucose and amino acids to the cells and remove waste substances such as carbon dioxide and urea away from the cells.
my professor said it would be nonsense codon. hope it helps!
They react to external factors like light, temperature etc
If we sprinkle salt on cucumber slices, it releases water after some time due to the process of osmosis. Osmosis is a process where solute or salt from higher concentration moves towards lower concentration through a semi-permeable membrane. Here, in this case, the salt concentration is more outside on the cucumber slices. The individual cell membrane of cells present in cucumber slices acts as a semi-permeable membrane. Inside the cucumber cells, there is less concentration of salt or solute and more concentration of water. Therefore, the salt from outside goes inside individual cells and the water comes out as it also travels from higher concentration to outside lower concentration through a semi-permeable membrane.
