Answer:

The answer is C

Explanation:

Therefore, in order to swim in the English channel, in which its waters are extremely cold, we need  carbohydrates like glucose that provide 4 kilocalories per gram. ... Fats are much more energetic foods, producing about 9 kilocalories of energy per gram, more than double that of sugar. Experts recommend that no more than 30% of the calories in our diet come from fat.

If a hypothetical cell contained 1% saline and 5% glucose, approximately what
liraira [26]

The hypothetical cell will approximately contain 94 percent (94%) of water.

  • If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.

  • If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.

  • Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.

  • In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).

UNO [17]

Answer:

Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.

Explanation:

Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.

The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.

Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.

Regarding other options:

  • <em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
  • <em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy. </em>
  • <em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
