Answer:
Option B, they negate each other
Explanation:
Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.
Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
Option B
Microtubules originate on the centre of the cell taking the positive end to the periphery of the cell, while the negative end remains turned to the centre of the cell. The melanosomes move along these microtubules using motor proteins desiganted kinesins and dyneins. The kinesins are responsible for moving the melanosomes to the positive end of the microtubule (periphery of the cell) generating dark-colored cells, whereas dyneins move the melanosomes to the negative end of the microtubule (centre of the cell) generating light-colored cells.
Answer:
The correct answer is: mutualism
Explanation:
Mutualism refers to a relationship between two organisms, where both organisms benefit from the association. In this instance, the relationship between cellulose-digesting microorganisms and their hosts- termites and ruminant mammals- is characterized by mutualism because both organism benefit from their association. The microorganisms benefit by getting their nutrition from the cellulose in guts of their hosts. Whereas, the hosts benefit from the cellulose-digesting microorganisms by getting help in digesting the cellulose they consume in their diet.
They are usually held out for a period of FOUR TO SIX WEEKS after diagnosis. Splenomegaly is an infectious disease that corrupt the spleen and the enlarged spleen usually persist even after all the symptoms have disappeared. Because of this, athletes should not resume active exercise too soon. Generally, the shortest period after which it is okay to resume active exercise is four weeks after all the symptoms have gone.
