Question

Diff. tan inverse ( root 1+x square -1 / x) w.r.t sin inverse (2x/1+x square)​

Answer 1

Step-by-step explanation:

यू अमित अमित अमित अमित अमित water gathers in the hollowed portions of the potato cup. 

(

Experimental set up 

(i) Water gathers in the hollowed portions of set-up B and C because water enters 

the potato as a result of osmosis. Since the medium surrounding the cell has a 

higher water concentration than the cell, the water moves inside by osmosis. Hence, 

water gathers in the hollowed portions of the potato cup. 

(ii) Potato A in the experiment acts as a control set-up. No water gathers in the 

hollowed portions of potato A. 

(iii) Water does not gather in the hollowed portions of potato A because potato cup A 

is empty. It is a control set-up in the experiment. 

Water is not able to enter potato D because the potato used here is boiled. Boiling 

denatures the proteins present in the cell membrane and thus, disrupts the cell 

membrane. For osmosis, a semi-permeable membrane is required, which is disrupted 

in this case. Therefore, osmosis will not occur. Hence, water does not enter the 

boiled potato cup.
