Identify a scenario where an experiment would be replicated
Vsevolod [243]

Answer:

If you did not follow the procedure as you should have.

Explanation:

You may have to repeat an experiment for several reasons. It can be because you need to be certain of the results so that you have to perform it several times. Or you need more precise results so that you can fine-tune the variables and repeat the experiment again.

The most common scenario where an experiment would be replicated would be in a situation where you did not follow the procedure that you have outlined exactly like you should have so that the results you got are not 100% reliable. In such a case, the experiment would need to be replicated for the correct results.

I hope this answer helps.

Why is the ability of the cell membrane to be "picky" important?
Yuliya22 [10]

Answer:

Hi there!

Your answer is:

It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive

Hope this helps

N a jungle habitat, there lives a species of snake, called Species A. The carrying capacity of the jungle allows 5000 of Species
OLEGan [10]

Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D

<h3>What is carrying capacity of a habitat?</h3>

The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.

The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.

Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.

In conclusion, the competition between the species of snakes is responsible for the decline in Species A.
