Answer:

why do you think that 100 sperm cells are released during ejaculation if only one sperm is needed to fertilize an egg?

Millions of sperm cells are produced as a result of ejaculation but during swimming to the egg only few make it to the egg while just one is being fertilized.

The reason is not far-fetched because the higher the population produced the higher the competition which led to one that survives it.

If few were produced and during the cause of swimming to the egg, they die along the line. There would not be any sperm cell to be fertilized

So at least 5 sperm finds it's way to the egg. Since sperm die out before even finding it, we need as many as possible to try it to find the egg.

marusya05 [52]

Answer:

A. A water molecule passes through a semi permeable membrane

Explanation:

Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.

In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.

Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.

Answer choice A is correct because the water molecule was able to pass through by itself.

So, the correct answer is A. A water molecule passes through a semi permeable membrane

Wittaler [7]

Answer:

the order would be:

Carnivorous animal -> scavenger animal ---> autonomous living organism ---> decomposing organisms.

Explanation:

The lion would be the carnivore, the bird that eats the waste of dead meat would be the scavenger, the vegetable the autonomous, since it does not require an external energy source to live but synthesizes its own energy and finally the decomposers fulfill the function to decompose chemical compounds to give energy to the earth, which would be useful for the growth of other living organisms. This is how the chain meets the cycle of life.
