1) a) Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
What are the following options?? i cant help if you don’t but the whole question
Answer: Option B
Explanation:
The sodium pump is used to control the osmolarity of the cell by pumping the sodium ions out of the cells that have diffused inside the cells due to their high electrochemical gradient.
This pump plays an important role in the neurons and helps in initiating the action potentials.
This pump helps in the signals transduction from brain to various parts of the body.
Hence the correct answer is that this" Pump Na+ out of the cell".
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal
The image was missing from the question.
The correct answer is genetic drift.
As you can see, the image presents a large amount of fish being caught by a fishing net. The genetic drift is one of the four mechanisms of evolution and it changes the frequencies of alleles in the population randomly.
In our case, the fishes caught by the fishing net are not going to reproduce and pass on their genetic material, therefore changing the genetic structure of the next generation. This event is solely random ( there is no mechanism of selection which individual fish is going to be caught).
