The plasma membrane of axon is called axolemma. The potassium and sodium leak channels leak the sodium and potassium ions inside the cell respectively. The leak channels provide the constant movement of ions across the membrane. Potassium and sodium ions are positively charged, thus entry of positively charged ions inside the cell makes the cell more positively charged than the environment outside the cell. The environment outside the cell becomes more negatively charged. This leads in the negative membrane potential of axolemma.
To be accepted, a scientific argument must first proved it's solidity and validity and critiques from other expert is usually the best way to explain both the solidity and the validity of a scientific argument

Answer:
I think the answer is C: An experiment that includes one group for which the scientist controls all variables
Explanation:
D-As stress levels increase, job efficiency increases is the correct answer.
Answer:
The correct answer is A) differentiated cells retain all the genes of the zygote
Explanation:
A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.
All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.
This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.
