The food preservation method in which moisture present in food is removed is called ________.
To every action there is always an equal and opposite reaction. Which of the following statements is correct regarding this?
A The buggy pulls the horse backward just as hard as the horse pulls the buggy forward. Both of them would not move forward if surface is frictionless.
B The horse pulls the buggy forward slightly harder than the buggy pulls the horse backward, so they move forward.
C The horse can pull the buggy forward only if the horse weighs more than the buggy.
D None of these
Does anybody know the solution?
Ans 3: (Master Answer)
The correct answer is A.
The buggy pulls the horse backward just as hard as the horse pulls the buggy forward. Both of them would not move forward if surface is frictionless.
Refer to the given Venn diagram and select the correct statement regarding X, Y and Z.
A Deficiency of X and Y causes night blindness and scurvy, respectively.
B X helps in the normal growth of bones in children while Y keeps reproductive system healthy.
C Deficiency of Z causes pellagra i.e., vitamin complex.
D Y is a group of several vitamins.
Ans 9: (Master Answer)
The correct answer is B.
In the given Venn diagram X, Y and Z represent vitamin D, vitamin E and vitamin K, respectively. Deficiency of vitamin A causes night blindness and deficiency of vitamin C causes scurvy. Pellagra is caused by deficiency of vitamin B3. Vitamin B is a group of several vitamins like B1, B2, B3, B6, B12 and folic acid and is known as vitamin B complex.
Refer to the given graph showing the amount of undigested food during the process of digestion in the gut and select the correct option.
A X is small intestine.
B Y is large intestine.
C Z is oesophagus.
D P is large intestine.
Can you say me how X is oesophagus, Y is stomach, Z is Small Intestine and P is Large Intestine
Ans 5: (Master Answer)
The correct answer is D.
X is oesophagus with no change in amount of undigested food. Y is stomach and Z is small intestine with decreasing amount of undigested food and P is large intestine as no further digestion occurs here.
A unicellular protist X, which has contractile vacuole to remove excess intracellular water, was placed in salt solution of increasing osmolarity. The given graph shows the rate of contraction of vacuole to pump out excess water against osmolarity of solution.
Select the option that gives the correct explanation of the data.
A In an isotonic solution there is no diffusion of water in or out of the X, so the contraction rate is zero.
B At higher osmolarity, more salt diffuses into X, therefore lower rates of contractions are required.
C The rate of contraction increases as osmolarity decreases because amount of water entering X by osmosis increases.
D The contractile vacuole is less efficient in solution of high osmolarity because of reduced respiration and less production of ATP.
what s the answer
Ans 2: (Master Answer)
The answer is C
The rate of contraction increases as osmolarity decreases because amount of water entering X by osmosis increases.
It the pattern continues in the same way, then what would be the 11th number in the pattern ?
1, 2, 5, 10, 17
Read the given passage and select the correct option for X and Y.
Microorganisms are used for the large scale production of alcohol, wine and acetic acid. X is used for commercial production of alcohol and wine. The process of conversion of sugar into alcohol is known as Y.
A X : Streptococcus; Y : Aerobic respiration
B X : Saccharomyces Y : Fermentation
C X : Lactobacillus; Y : Fermentation
D X : Saccharomyces; Y : Aerobic respiration
Isn't it C?
Ans 3: (Master Answer)
The correct answer is B
Microorganisms are used for the large scale production of alcohol, wine and acetic acid. Yeasts are mainly used in the commercial production of wine, beer and other alcoholic drinks. The main yeast species used is Saccharomyces cerevisiae. The process of conversion of sugar into alcohol is known as fermentation.

Arrange them in a correct sequence.
A (ii) → (i) → (iii)
B (i) → (ii) → (iii)
C (i) → (iii) → (ii)
D (iii) → (i) → (ii)
I think the correct answer is C.
