What are convection currents

Answers

Answer:

Convection is the transfer of heat due to the bulk movement of molecules within fluids, including molten rock.

Explanation:
(a current in a fluid that results from convection.)

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

The chemical and mechanical processes of food breakdown are called ________.A. digestion
B. absorption
C. ingestion
D. secretion

Answers

Digestion refers to the chemical and mechanical processes that break down food.

What is digestion?

Digestion is the process through which food moves through our bodies, with the goal of giving energy to the body or constructing new cellularcomponents and tissues, such as muscle and fat.

How does digestion take place?

  • When food enters the mouth, it is mechanicallydigested (chewing) and becomes when it comes into touch with saliva. Saliva contains salivary amylase, which helps food digest starch. Salivaryamylase is a digestive enzyme that starts the digestion of starch in meals.
  • The food will be in the form of a small, round slurry mass known as a bolus after mastication and starch digestion.It moves down the esophagus and into the stomach due to peristalsis.
  • In the stomach, gastric fluids beginprotein digestion.Pepsin and hydrochloricacid are the main components of these juices. Because the HCl may harm the stomach wall, the stomach secretesmucus, which forms a sticky covering that protects the stomach from the acid's harmful effects.
  • Peristalsis, a mechanical mixingprocess that permits the mass of food to interact with the digestiveenzymes, occurs concurrently with protein digestion.
  • After some time, a thick liquid called chyme is produced, which enters the duodenum and mixes with pancreatic digestive enzymes and liver bile juice before passing through the smallintestine. After the chyme has been entirely digested, it is taken into the bloodstream, where it forms a stickybarrier that protects the body from the acid's harmful effects.

Thus, we can conclude that option A is correct.
