Do you predict that salt will be able to move across the membrane?1. Yes, because NaCl is small
2. Yes, because NaCl is ionic
3. No, because NaCl is large
4. No, because NaCl is ionic

Answers

Answer 1
Answer:

Answer: The correct answer is

No, because NaCl is Ionic

Explanation:

NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.

Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.

Which of the points of natural selection is also referred to as "survival of the fittest"? More offspring are born than can be supported by the environment. If too many offspring are born, they will be forced to compete for resources. Genetic variation leaves some offspring better adapted to their environment than others.

Answers

The third one is the answer.The first one is overproduction.The second one is competition.The third one is survival of the fittest, because if there are six grey mice and two brown mice in a brown field, which is more likely to be eaten by a predator? The grey mice are. Their genetic material helps them to survive and therefore be fit to their environment.
