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

Answers

Answer 1
Answer:

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.

how is nitrogen from the atmosphere, the aiotic part of the ecosystem, converted into the biotic part of the ecosystem n organisms

Answers

In the process of the nitrogen cycle.                 
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA.  

An organism has the following traits: Unicellular no nucleus contains DNA which kingdom does it most likely belong to??A. Animalia
B. Bacteria

Answers

B. Bacteria 

 Unicellular organisms are not that complicated in terms of parts. They are not made to have a lot of systems and are very much suited to flourish in many places.       
Unicellular organisms are not seen to the naked eye. Because of this, unicellular organisms are not easily identified by a lot of predators except of their own kind.

Sponges have...a. a coelom
b.tentacles
c. specialized cells
d. bilateral symmetry

Answers

Answer:

c. specialised cells

Explanation:

Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.

Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.

Final answer:

Sponges have specialized cells that perform specific functions like filtering food and excreting waste. They do not have a coelom, tentacles, or bilateral symmetry.

Explanation:

Sponges have specialized cells. These cells are responsible for the various functions of sponges, such as filtering their food and excreting waste. Some examples of specialized cells in sponges are collar cells, which line the inside of the sponge and generate water flow, and amoebocytes, which transport nutrients throughout the sponge. Sponges do not have a coelom, tentacles, or bilateral symmetry.

Certain integral membrane protein of the erythrocyte was the first membrane protein to be sequenced and is highly glycosylated, a feature which is thought to be responsible for these cells repelling each other and not clumping together in blood vessels. That protein is:_______.

Answers

Answer:

Glycophorin

Explanation:

The red blood cells possess the membrane-spanning proteins integrated into the cell membrane called glycophorins.

These glycophorins are composed of the sialic acid and the glycoproteins and these molecules allow the formation of the hydrophilic bonds. These molecules allow the easy circulation of the blood cells in the blood vessels without clumping in the vessel and interacting with the blood vessels.

Thus, Glycophorin is correct.
