A school’s environmental club wants to reduce the ecological footprint that the student body creates annually. Which step would
Monica [59]

<u>Answer:</u>

Composting food scraps in the cafeteria to reduce landfill waste would have the greatest impact in reducing the school’s ecological footprint.

Option: (C)

<u>Explanation:</u>

  • Reducing the ecological footprint means bringing about some changes in lifestyle and living to improve the biocapacity.
  • Compositing food scraps in the cafeteria to reduce landfill waste is the best option that the environmental club can apply to reduce the school's ecological footprint.
  • This step can help to increase productivity of soil as well as reduce waste in landfill site.
  • The option of incineration of trash causes air pollution. Likewise, reducing recycling bins will not be helpful in decreasing the ecological footprint.
  • Instead, it causes the unmanaged collection of trash in school environment.

During glycolysis, two hydrogen atoms are picked up by the coenzyme nicotinamide adenine dinucleotide (NAD). What B vitamin is r
Maslowich

Answer:

Niacin (Ans. A)

Explanation:

Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.

Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.

These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.

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.

What would happen if the cell membrane only had 1 layer of phospholipids?
Fofino [41]

Answer:  

If phospholipid bilayer diffusion is normally negligible, there will be tissues (largely lacking in transporters that may be expressed elsewhere) which, despite the relative functional similarity of their phospholipids, are very poor at taking up drugs: the blood–brain [33], blood–testis [34], and blood–retina
