What is mechanical digesion?
Mechanical digestion is the act of chewing and using your tongue to mix the food with saliva.
What is the function of the mouth on a crayfish?
Yes, they have three sets of maxillipeds, which tear the the food apart. The maxilla also rips the food side to side. The mandible does the final grinding and it also help pass the food into the deepest part of the mouth which contain the lateral/median teeth.
How will the time taken for starch to digested in amylase be affected by the temperature?
The time taken for starch to be digested by amylase will decrease as the temperature increases up to an optimal range. This is because higher temperatures speed up enzyme activity. However, if the temperature exceeds the optimal range, the enzyme may denature, leading to a decrease in digestion time.
What is the function of the serous gland?
It's basically a layer or layers of tissue covering most of the body's "canals" like the stomach, intestine, blood vessels, etc. Some serosa secrete mucus-like substances like in the case of the stomach and intestine which reduces friction when foods are passing in. However, some serosa ang muscular, meaning, they contract, most of the time, involuntarily. Some serosa are also epithelial in nature. These are usually found covering lining the outermost layer.
Why does the air never run out?
the reason why do we run out of Corbon dioxide is,it is not required for us as an important substance. It is gnerated in our body as a product of respiration and also during digesion. More over we are not using it for important body function. we generate a lot of carbon dioxide,we let it out as a substance which is not required, so we dont run out of carbon dioxide.
What organelles perform the digestive function of the cell?
The digestive organelles of a cell are - peroxisomes, vesicles/vacuoles and lysosomes.Peroxisomes are single membrane sacs that contain digestive enzymes that break down toxic materials in a cell. They also break down fatty acids to sugars.Vacuoles/vesicles are found in plant cells and some animal cells. Vacuoles and vesicles are membrane bound but the vacuoles are stationary and vesicles can move within the cell.Vacuoles are of three different types - food vacuoles, contractile vacuoles and central vacuoles.food vacuoles are involved in ingesting food into the cell through a process called phagocytosiscontractile vacuoles are found in fresh water protists and are involved in pumping excess water out of the cellcentral vacuoles are found in mature plant cells that store water so that the plants do not dieVesicles are of two different types -transport vesicles that take the protein from the rough Endoplasmic Reticulum and transport it to the Golgi Bodiessecretory vesicles that carry the finished proteins to the cell membranesLysosomes are vesicles that are sacs containing digestive enzymes, These are found only in animal cells. Their function is to digest macromolecules and clean up any dead organelles. For cellular digestion the lysosomes fuse with the food vacuole to break down the polymers.
