Answer : 1. "quality, quantity and duration of light"
Explanation :
Answer: A) quality, quantity and duration of light Explanation: Plants and animals are separated by about 1.5 billion years of evolutionary history. They have evolved their multicellular organization independently but using the same initial toolkit — the set of genes inherited from their common unicellular eucaryotic ancestor. Two basic peculiarities of plants are: First, they get their energy from sunlight, not by ingesting other organisms. This dictates a body plan different from that of animals. Second, their cells are encased in semirigid cell walls and cemented together, preventing them from moving as animal cells do. This dictates a different set of mechanisms for shaping the body and different developmental processes to cope with a changeable environment. Because they cannot match themselves to their environment by moving from place to place, plants adapt instead by altering the course of their development. Their strategy is opportunistic. A given type of organ—a leaf, a flower, or a root, say—can be produced from the fertilized egg by many different paths according to environmental cues. Hence, Plant development is influenced by quality, quantity and duration of light.

Answer : 3. "5223"
Explanation :
Answer: C) 5223 Explanation: Given, 25% of three-seventh of 26% of a number is 145.5 Let the required number be 'N' i.e, 25100x37x26100xN = 145.5 N = 145.5x7x1000075x26 => N = 5223.07

Answer : 4. "Lithium"
Explanation :
Answer: D) Lithium Explanation: Electronegativity is the tendency for an atom to attract electrons. There are general trends on the periodic table which you can use to determine the relative electronegativity for different elements, but otherwise you can also look at their valence shell and effective nuclear charge to determine their relative electronegativity. Here from the given options, Lithium has least tendency to attract electrons and thus has a lower electronegativity.
