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

The correct answer is:
A-4, B-3, C-2, D-1

Solution:
Floral formula is the representation of the count and arrangement of the whorls of the flower. It is unique for a particular family of flowering plants and symbols are used for representation. 'A' signifies male reproductive part androecium. Similarly, G is for gynoecium, K for calyx and P for corolla.
Androecium is the male reproductive part of the flower having stamen made of filament (stock) and the anther. Anther is the sac like structure where the male gamete containing structures, pollen grains are formed.
Fabaceae, a.k.a. Leguminosae is the family of plant having legumes, peas group in them. This group is the third largest group and economically important family of flowering plants. The male part in floral diagram is represented as A9+ 1 , meaning 10 stamens are present of which 9 are fused and 1 is not-attached with anther been dithecous.
Solanaceae also called 'potato family' are found in regions of tropics, subtropics and temperate zones. Mostly have herbs and shrubs types of plants. The male reproductive part in the floral formula is A(5), where there are 5 fused stamens and they are epipetalous.
Liliaceae, the lily family, form the representative of the monocot plants. Its as six stamens arranged in sets of three without fusion.
Brassicaceae includes the mustard plant group where the 6 male parts (stamen) of flower are arranges as sets of 2 and 4 without been fused. They are diadelphous.

Deficiency of iodine in our diet results in hypothyroidism and enlargement of the thyroid gland; the condition is called goitre. Hypothyroidism during pregnancy in mothers causes cretinism in children. In hyperthyroidism, the rate of synthesis and secretion of thyroid hormone increases leading to higher hormone levels than normal, which leads to exophthalmic goitre or Grave's disease. Calcitonin decreases but parathormone increases blood calcium level.

Another bioactive molecule, cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungus Trichoderma polysporum. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for synthesis of cholesterol.

Synthetic auxin 2, 4 D is used as a weedicide and is used to remove dicot weed from monocot field.ABA commonly called as stress hormone causes closure of stomata. Ethylene is only gaseous hormone and it causes ripening of fruits.GA causes rapid intermodal elongation in genetically dwarf plants or rosette plants, the phenomenon is known as bolting. Cytokinin was first isolated by autoclaving herring fish sperm DNA.

Match the following.

Column I	Column II

(1) Mg2+	(i) Chlorophyll

(2) P	(ii) ATP

(3) Zn	(iii) Alcohol dehydrogenase

(4) Mo	(iv) Nitrogenase

Options:
A 1–ii, 2–i, 3–iii, 4–iv
B 1–i, 2–ii, 3–iii, 4–iv
C 1–iv, 2–i, 3–ii, 4–iii
D 1–iv, 2–iii, 3–ii, 4–i

The correct answer is:
1–i, 2–ii, 3–iii, 4–iv

Solution:
Chlorophyll is the green colour pigment found in the photosynthetic organisms. This pigment is responsible for absorbing the light energy and convert into chemical energy to be used in making glucose. The general structure of chlorophyll consists of a chlorin ring with a Mg2+ ion surrounded by four nitrogen atoms in the central part of the ring. The ring is attached to several side chains and long hydrocarbon tail. Adenosine triphosphate a.k.a. ATP is the energy molecule required for regulating various metabolic processes. ATP is a nucleoside triphosphate having adenine as nitrogen base, ribose sugar and three phosphate groups. These phosphates have phosphorous as the core element.
Alcohol dehydrogenase is a type of enzyme that facilitates interconversion between alcohol and aldehydes or ketones by reducing NAD to NADH. These enzymes are known to contain Zn which plays a structural role and significant for the stability of the protein.
Nitrogenase enzymes are responsible for converting nitrogen to ammonia by reduction. It contains Molybdenum required for the proper activity of the enzyme in catalyzing the reaction.

Match the following.

Column I	Column II

A	Epinephrine	i	Stimulates muscle growth

B	Testosterone	ii	The decrease in blood pressure

C	Glucagon	iii	Breakdown of liver glycogen

D	Atrial natriuretic factor	iv	Increases heartbeat

Options:
A A-ii,Â B-i,Â C-iii,Â D-iv
B A-iv, B-i, C-iii, D-ii
C A-i,Â B-ii,Â C-iii,Â D-ivÂ
D A-i,Â B-iv,Â C-ii,Â D-iii

The correct answer is:
A-iv, B-i, C-iii, D-ii

Solution:
A. Epinephrine increases the alertness, pupillary dilation, piloerection (raising of hairs), sweating, etc. The hormone increases the heartbeat, strength of heart contraction and the rate of respiration.
B. Testosterone is responsible for muscular growth, aggressiveness, development of facial and axillary hair, low pitch of voice, etc.
C. Glucagon functions as 1. Stimulating glycogenolysis. 2. Stimulating the process of gluconeogenesis. 3. Reducing cellular glucose uptake and utilization.
D. Atrial natriuretic factor - ANF is a peptide hormone secreted from the atrial wall. Whenever there is an increase in blood pressure â release of ANF â dilation of the blood vessels â decreases in blood pressure.
