Question 4
1 / -0

Some functions of nutrient element are given below
I. Important constituent of proteins involved in ETS.
II. Activator of catalase.
III. Important constituent of cytochrome.
IV. Essential for chlorophyll synthesis.
The concerned nutrient is

A
$$Cu$$

B
$$Fe$$

C
$$Ca$$

D

List-I(Essential elements) List-II(Deficiency symptoms)
a. Boron $$1$$. Die-back disease
b. Copper $$2$$. Interregional chlorosis
c. Iron $$3$$. Little leaf disease
d. Zinc $$4$$. Terminal leaf necrosis

A
A-$$1$$, B-$$4$$, C-$$3$$, D-$$2$$

B
A-$$1$$, B-$$4$$, C-$$2$$, D-$$3$$

C
A-$$4$$, B-$$1$$, C-$$3$$, D-$$2$$

Question 8
1 / -0

Ribulose phosphate is a ____________.

A
Aldose sugar

B
Ketose sugar

C
Disaccharide

D
Trisaccharide
Question 9
1 / -0

The first stable product of fixation of atmospheric nitrogen in leguminous plant is

A
$$NO_{2}^{-}$$

B
Ammonia

C
$$NO_{3}^{-}$$

D
Glutamate

Solution

$$\underset {Nitrogen}{N_{2}} \rightarrow \underset {Dimide}{N_{2}H_{2}}\rightarrow \underset {Hydrazine}{N_{2}H_{4}} \rightarrow \underset {Ammonia}{2NH_{3}}$$
The fixation of atmospheric nitrogen to ammonia is given as
$$N_{2} + 8e^{-} + 8H^{+} + 16ATP \underset {Nitrogenase}{\xrightarrow {MO-Fe}}2NH_{3} + H_{2} + 16ADP + 16Pi$$
The process in which atmospheric nitrogen gets concerted into inorganic nitrogenon (nitrate, ammonia) compounds through microorganisms is called biological nitrogen fixing.
Question 10
1 / -0

What is the key principle of the EBB and flow system in hydroponics?

A
It floods and drains periodically

B
It makes a tide flowing over the roots

C
It sprays a mist of nutrients on the roots

D
None of the above

Solution

Ebb and Flow, or Flood and Drain is a system involves the periodic flooding and draining of the nutrient solutions. Basically, there are two phases of its operation. The Flood is when the water and nutrients flow the growing areas, flowing over the plants' roots. The drain is when the water drains back to the reservoir. These two actions take turn continuously, and hence their name.
So, the correct option is ‘it floods and drains periodically’.
