Assoli18 [71]

Answer:

<h2>Catabolite repression </h2>

Explanation:

1. Catabolite repression: it is the positive control of the lac operon.

2. It  results in an increase in the rate of transcription. Here, the CAP protein is activated by cAMP  which then bind to the lac operon and facilitate the binding of RNA polymerase to the promoter to transcribe the genes for lactose utilization.

3. Role of glucose in catabolite repression is that It stimulates transcription from the lac operon, causing an increase in cAMP levels in the cell. Glucose decreases the levels of cAMP in the cell, result in repressing transcription from the lac operon.

Please help will do anything! Which of the following can be determined by this diagram?A.The energy of the mongoose is passed on
N76 [4]

Answer:

C

Explanation:

The arrows in this food web represent energy flow.

A. The energy of the mongoose is passed on to the hare.

The arrows points from the hare to the mongoose, which indicates the energy moving from hare to mongoose. Therefore,A is not correct.

B. The cheetah supplies energy to a variety of organisms.

There are no arrows that point from the cheetah to another organism. The arrows point from the other animals to the cheetah, indicating the cheetah is a top predator. So, B is not correct.

C. The energy of the acacia tree is passed on to the impala.

The acacia tree passes its energy onto termites, and these termites pass their energy onto the impala. Therefore, C is correct.

D. The aardvark, pangolin, and mongoose are all producers.

This is not true, because these are all animals. Producers are typically plants. Additionally, the producers are usually at the bottom of a food web.

So, C is the correct choice.

Question 8 of 10
Aleks [24]

Answer: C. 2 ft

Explanation:

if the scale is 1:2,000

This means that if the original plane flyes 2,000ft above the ground, the model plane will fly 1ft above the ground.

Now, if the plane flies 4,000ft above the ground, this is two times as the number from above, then the model plane will also fly two times as the number from above.

2*1ft = 2ft.

Now, we also can do it as:

2000ft equiv to 1 ft.

4000ft equiv to x

x = 1ft*(4000ft/2000ft) = 1ft*2 = 2ft.
