You start a PCR with 1,000 molecules of DNA, an excess of primers and an excess of nucleotides. The PCR works perfectly and each

round of PCR doubles the amount of DNA present. How many molecules of DNA would be present after 11 rounds of PCR?

Answer:

2.048 x 10^6 No. Of Copies

Explanation:

The DNA replication in a PCR works exponentially by using the 2^n where n represents the number of cycles.

For one molecule of DNA = 2^11 = 2048 No. Of Copies

For 1000 Molecules of DNA = 1000 x 2048 = 2.048 x 10^6 No. Of Copies

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.

Field mice in beach mice are closely related species. The Field mice are various shades of brown in the beach mice or later 10 a
wariber [46]

Answer:

The process of natural selection is acting on <u>Field mouse individuals</u> where as evolution is occurring on <u>Field Mouse population. </u>

Explanation:

As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.

Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)

Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.
