1a. Pseudopodia means false feet these are irregular projections found in organisms like amoeba,they help the organism in locomotion capture food etc
1b.a good vacuole is a membrane-enclosed cell vacuole with a digestive system,containing material taken up in by the process of phagocytosis.these are found in amoeba,Protozoa,paramecium
2.the ingestion of bacteria or other material by phagocytes and amoeboid protozoans (wasn’t sure for this one so I had to research)
3.amoeba takes in nutrition by the process called phagocytosis.in this process,a solid food particle is first surrounded by pseudopodia (cytoplasmic filled projection of cell membrane) and forms a vacuole called as Phagosome

A huge amount of water − 7 to 9 l − moves from the blood into the bowel every day, through osmosis and digestive secretions. sin

Alexus [3.1K]

The event order should be:

1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume

Why does a Mosquito insert his saliva after biting ?

kow [346]

Answer:

When the female mosquito pierces the skin for her “blood meal”, she injects a small amount of saliva into a capillary. The saliva makes penetration of her proboscis or mouthparts easier and prevents the blood from clotting.

Can somebody do 4 and 5 for me

Dafna1 [17]

Answer:

4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.

5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.

Explanation:

4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.

5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.

pH: when the pH increases or decreases it produces a decrease in the speed of reaction that catalyzes an enzyme. Very high or low pH levels can denature the enzyme and make the expected reaction not occur.
Temperature: like pH, changes in temperature can slow or stop maltase activity.
Substrate availability: It is a fact that when the specific substrate of an enzyme becomes depleted, the rate of reaction slows down, stopping when no substrate is available.
