Question

15. Name the cell organelle found in an animal cell where secretion of enzymes occur. What is the function of these enzymes?

Answer 1

Answer:

lysosomes

In animal cells, the lysosomes are the cell's “garbage disposal.” Digestive enzymes within the lysosomes aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, and even worn-out organelles.

Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.

Explanation:

Answer 2

skisha the time taken to move upward=time taken to move downwad

so the time taken by the stone to come down from the highest point=2 s

so from 2 nd equation of motuion,as it was moving down: 0+1/2 gt2=h

h=5x2x2=20 m

so ut-1/2 g t2=20 while moving up

2u-20=20

u=20m/s

ie the distance it covered in t=1 sec from the highest point:h=5t2=5m
