Answer:

All living organism on earths are similar on the basis of life process and chemical composition of the genetic material.

Explanation:

All living organisms perform the basic life process like respiration, digestion, reproduction and excretion. The simple basic organisation of living organisms is the cell. Cell is the structural and functional unit of all the living organism.

All living organisms are made up of similar types of nucleic acids. DNA is present as genetic material in all the organism except some viruses. Living organism present on earth follows the molecular central dogma that refers the process of replication, transcription and translation.

Damaged tissue releases chemicals that activate platelets and stimulate the formation of blood clots. Which of the following pre
Zielflug [23.3K]

Hello! I figured your question was lacking its options so I went online to find them and here they are:

A. Activated platelets release chemicals that  inhibit blood clot formation.

B. Activated platelets release signaling  molecules that inhibit cell division in  damaged tissue.

C. Activated platelets constrict the blood  vessels, stopping blood flow.

D. Activated platelets release chemicals that  activate more platelets.

Answer:

The correct answer is: D) Activated platelets release chemicals that  activate more platelets.

Explanation:

<u>Positive feedback</u><u> is a mechanism in which a stimulus triggers an intensification of this same stimulus.</u>

When a tissue is damaged, the platelets participate in a process called platelet adhesion that consists of contacting and sticking to the collagen fibers of the connective tissue under the damaged endothelial cells. This platelet adhesion <u>activates</u> the platelets and makes them grow projections to contact and interact with one another, while releasing substances to activate other nearby platelets. The accumulation and the attachment of large numbers of platelets ultimately form a <u>platelet plug</u>.

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.
