3241004551 [841]

Answer:

Dr. Alexander is a scientist who studies a certain type of fly. In his studies, he came across information that says that the fly doesn't need any calcium in its diet. This question interests him because he doesn't think it is true. He decides to create an experiment that will test whether this question is true. His hypothesis is that a fly will not live without calcium in its diet.

Dr. Alexander believes that flies must have calcium in their diet. In one of Dr. Alexander’s experiments, he feeds one hundred flies a normal diet with calcium. Then he feeds one hundred more flies a diet without calcium. Over seven days he records the following data:

Fed Calcium Not Fed Calcium

Flies alive before test 100 100

Flies alive after test 92 10

Based off the data above what would be a valid conclusion Dr. Alexander could make?

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.

gogolik [260]
So: both parents' genotypes (concerning baldness gene) are the same: Bb. Possible genotypes of an offspring: BB, Bb, Bb, bb . bb means non-bald girl or boy. Bb means bald boy or non-bald girl. BB means bald boy or girl. there is 25% chance of conceiving a child with a genotype BB. But there is also 50% chance of conceiving a girl. So the answer is: 25% x 50% = 12,5%
