If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?
Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.

Describe the passage of a meal containing bread through your digestive system
Alex777 [14]

Before your food passes from the mouth and down your esophagus, salivary amylase, an enzyme in saliva, begins to digest the starch in your bread. That is the start of chemical digestion. ...

You determine that you have only three copies left of an important DNA fragment, so you decide to amplify it. Using flanking pri
kicyunya [14]

Hello. This question is incomplete. The full question is:

"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment? "

Answer:

Approximately 29 cycles of PCR would be required.

Explanation:

As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.

PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.

In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:

32 ^ x = 10 ^ 9

x = 28.3 = approximately 29 cycles.
