Answer: FALSE
Explanation:
The plasma membrane has both Na –K channels across it walls. They are membrane transport proteins which hydrolyse ATP s for the active transport mechanisms for transport of sodium and potassium ions across the plasma membranes .
Naturally,there are more potassium ion channels than sodium channels in plasma membrane; potassium is also extracellular while sodium is extracellular
Therefore ,when some potassium ions diffused into the Axoplasm, from the extracellular medium;;some potassium ions still move out BACK into the extracellular environments. Not all potassium are restricted from leaving .
This leakage occurs because of more available potassium ions channels than sodium ions, and higher number of available potassium ions
Thus the answer is FALSE
the ratio of diffusion <u>is 3 sodium out to 2 potassium in </u>
Bacteria and fungi, compete for the same ecological niche.
Answer:
B. plants use the energy from sunlight to produce food.
Plants use the light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
Answer:
Almost all of your body’s cells divide by mitosis. Meiosis is used to produce only one type of cell, and those are the gametes. During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes. In humans, these are sperm and egg cells.
