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.

Tascha is on a medication that increases the pH of the stomach and makes it alkaline. What is the effect of this medication?
Paha777 [63]
<span>The effect of this medication hinders pile production as well as mechanical digestion. Proteins are unable to break down due to pepsin with the addition of lipase being unable to break down fats. This encourages stomach cells to create more mucus in order to compensate.</span>

Drag and drop a term to match these examples with the correct level of organization. Organ Organ system Tissue
sineoko [7]

Answer:

This question is incomplete as the term to match with the level of organisation is not included, the terms are;

circulatory system

cardiac muscle

heart

human body

The ANSWER is:

Organ = heart

Organ system = circulatory system

Tissue: cardiac muscle

Explanation:

The level of organization of multicellular organisms is made up of cell, tissue, organ, organ system and eventually organism.

- The tissue is composed of several cell, which are basic units of any living organism. Cells that perform similar function come together to form the tissue. Example is the CARDIAC MUSCLE in this question, which is a muscular tissue made up of cells called myocardiocytes.

- Organs are structures formed as a result of collection of tissues with similar function. For example, the HEART is a circulatory organ made up of cardiac tissues, connective tissues etc.

- Organ systems is made up of organs that perform the same function in a living organism. In the case of the CIRCULATORY SYSTEM, it is made up of organs such as heart, blood vessels, lungs etc.

Once a neuron is stimulated and the membrane potential is depolarized, the depolarized axonal membrane is helped to return to it
Vadim26 [7]

Answer:

Explanation:

The cell membrane separates the cell from the outer environment. The extracellular fluid contains the sodium ions (Na+), chloride ions (Cl-), while intracellular fluid contains potassium (K +) and negative anions.

The potential difference arises when the membrane is selectively permeable to some ions. The resting potential is -70mV.  

When the neurons get excited, the sodium ions start to enter by sodium channels.  

Now there are more positive ions inside the cell membrane. It disturbs the resting potential i.e. -70mV. This stage is known as depolarization.

When the inside environment of the cell is more positively charged, the potassium ions start to move out of the cell. It goes out by the voltage-gated channels. Thus resting stage is maintained and it is known as repolarization.

But the initial stability of the cell membrane has to be maintained. To restore the resting stage, the sodium ions start to move out of the membrane and potassium ions enter into the cells again. This is an active transport and has done by the Na+ - K+ pump. Here 3 sodium ions move out and 2  potassium ions pumped into the cell through the plasma membrane.  

Thus the resting potential regains. The potassium ions come back into the cells against the concentration gradient and ATP provides the energy for this phenomena.

Diploid nuclei of the ascomycete Neurospora crassa contain 14 chromosomes. A single diploid cell in an ascus will undergo one ro
Leni [432]

Answer:

Amount of DNA in a diploid G2 nucleus after S phase has already undergone DNA replication hence the amount of DNA in a diploid nucleus in G1 would be 200 ng. As the organism is diploid, 200 ng of DNA would be carried on 14 chromosomes.
