Eukaryotic cells posses a nucleus the purpose of the nucleus is it stores DNA which is the genetic material for the cell DNA acts as an instruction manual for the other organelles in the cell. While prokaryotic cells do not have a nucleus they still have dna but it’s floating around freely
Answer:
The correct answer is- digestion, absorption, transport, elimination
Explanation:
The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.
In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.
This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.
Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.
Therefore the correct order are: digestion → absorption→ transport→ elimination.
Answer:
The correct answer will be option-C
Explanation:
Lead is a metal found in the Earth's crust which through human practices like using it in paints and other products cause lead poisoning in humans due to accumulation of lead in the body.
Lead poisoning can affect the child above 6 years and adults and prove harmful as its increased concentration can cause severe health problems common of which are the development of anaemia due to large consumption, brain damage, reduced mental growth and severe stomach ache.
Thus, Option-C is the correct answer.
The acidic environment of the lysosome and the lysosomal enzymes detach the ligands from their receptors.
Receptor-mediated endocytosis is a process in which cell surface receptors are employed for transporting substances such as proteins, hormones, and metabolites from extra-cellular matrix into the cells. Receptor-mediated endocytosis usually occurs through clathrin (a type of protein)-coated pits and vesicle and it allow only the receptor-specific substances to enter the cell. Under this process, molecule binds to protein receptors after which the receptor molecule moves to clathrin coated pits and vesicle. The cell membrane then folds inwards and there is fusion of a coated vesicle. After this, the ligands are detached from their receptors.
Loss of habitat from any number of causes is the main reason for species endangerment currently.
