Precocious Reproductive Development late in the growing Seasons-can be prevent by
Phenyl mercuric acetate (PMA) results in
Phenyl mercuric acetate (PMA) results in reduced transpiration. PMA is an antitranspirant. These are some chemicals whose limited application on the leaf surface reduce or checks transpiration. A good antitranpirant increases leaf resistance but does not affect the mesophyll resistance.
Major limiting factor for photosynthesis is
In C2 cycle there is synthesis of
In “Calvin Cycle” -
In Calvin cycle, we can see that about 6 molecules of carbon dioxide, 18 molecules of ATP, and about 12 molecules of NADPH are utilized and on the other side about 1 molecule of glucose, 18 molecules of ADP and 12 molecules of NADP are generated.

Sigmoid growth curve
It is an S-shaped graph produced on plotting growth of living organisms in their natural environment against time. This curve is divided into three phases: lag phase, log phase or exponential phase of rapid growth, and stationary phase.
Exponential growth can be expressed as:
W1 = W0 e^rt
W1 = Final size
W0 = Initial size
r = Growth rate
t = Time of growth
e = Base of natural logarithms
Antagonastic to ABA is
The two strands of DNA are held together by
Answer is option D i.e. "Hydrogen bonds"
The hydrogen bonds are formed between the base pairs of the anti-parallel strands. Base pairs are the building blocks of the DNA double helix. Base pairs consists of two nucleotide bases bound to each other by hydrogen bonds. The DNA helix is stable because of the base pairs that stack over one another and hydrogen bonds that hold the bases together.
Hence, answer is "Hydrogen bonds"
