Longitude is used to measure distances in degrees from the Prime Meridian. The correct option among all the options that are given in the question is the second option. The main purpose of longitude is to determine the east and west position of a point based on its geographical coordinate.

Explanation:
The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.
A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat. 
We need to find how many liters would that be.
We know that, 1 litre = 1000 milliliters 
1 mL = 0.001 L
To convert 80 mL to litres, we can do it as follows :
80 mL = (80 × 0.001) LL
= 0.08 L
Hence, he stroke volume of a person is 0.08 L/beat.
 
        
             
        
        
        
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.
