The phenomenon of ‘dormancy’ in seed germination refers to:
सही उत्तर: ख) A period of suspended growth and development in a seed, allowing it to survive unfavorable conditions.
Dormancy is a state of reduced metabolic activity in seeds that allows them to remain viable for extended periods under adverse environmental conditions. Options 1, 3 and 4 describe different stages or processes related to germination.

The process of osmosis primarily involves the movement of which substance across a semi-permeable membrane?
सही उत्तर: ग) Water molecules
Osmosis is defined as the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration), across a semi-permeable membrane. Options 1, 3 and 4 describe other transport processes.

In a group of people, 30% are men and 70% are women. If there are 15 more men than women, how many people are in the group?
सही उत्तर: ग) 60
Let 'x' be the total number of people in the group. The number of men is 0.3x and the number of women is 0.7x. We know that men = women + 15, so 0.3x = 0.7x + 15. Solving for x, we get -0.4x = 15, which means x = -37.5 – which isn’t possible. Instead we should use: Men - Women = 15; thus 0.3x - 0.7x = 15, so -0.4x = 15 and x = -37.5. This is a trick question. Let's think this through differently: let 'w' be the number of women. Then men = w+15. total people is w + (w+15) = 2w+15. Also, men are 30% and women are 70%, so we know that w/ (2w+15) = .7 or .7(2w+15) = w. Thus 1.4w + 10.5 = w which gives .4w = -10.5. This also doesn’t work. Let’s use numbers instead: if we take a group of 100, then men = 30 and women = 70. so difference is only 10, not 15. A group size should be much larger. Let's solve it differently: let the number of people be 'n'. Men = (3/7) * n, Women = (4/7)* n. The difference between men and women is 15 so (3/7) * n - (4/7) * n = 15, which implies (-1/7) * n = 15, or n=-105, again this cannot be correct. Let’s try it with w=100 women; men would be 15; total is 115. Still incorrect. Let's consider the number of people to be a multiple of 7. Suppose n = 35. men = (3/7)*35 = 15 and women = (4/7)*35=20 - difference between them would be 5, not 15. So lets try n = 70. men =(3/7)*70=30; women = (4/7)*70=40; so the difference is 10. Lets multiply by a factor of two to get 70*2 = 140. This means men would be 60 and women would be 80 – difference is 20, but this would be too large. Let’s consider the problem more closely: if we assume w as an integer multiple of 5; so let say w = 5k then men = 5k+15. total number is 5k + 5k+15 = 10k + 15. The percentage must be close to 70%. i.e. (5k+15)/(10k+15) = .7 – that gives 5k + 15 = 7k + 10.5; so, 2k=4.5 and k=2.25, which doesn’t give an integer value for w. Let's try another approach: The given options are not likely to yield a good solution. Let’s examine the option of 60 – that implies total people is about 60 or so.

If a shopkeeper sells an item for Rs. 80 and makes a profit of 10%, what was the cost price (CP) of the item?
सही उत्तर: ख) Rs. 75
If the selling price is Rs. 80 with a 10% profit, then the profit amount is 10% of 80 = Rs. 8. Therefore, the cost price (CP) = Selling Price - Profit = 80 - 8 = Rs. 72.

The following series follows a pattern: 1, 4, 9, 16, 25, ? What is the next number?
सही उत्तर: क) 30
This series consists of perfect squares (1^2, 2^2, 3^2, 4^2, 5^2...). Therefore, the next number in the sequence is 6^2 = 36.

Which of the following features is characteristic of cnidarians like jellyfish?
सही उत्तर: ख) Segmented body with repeated units
Cnidarians exhibit radial symmetry, with two distinct tissue layers (ectoderm and endoderm) and specialized stinging cells called cnidocytes. A complex nervous system is absent.

The symbiotic relationship between nitrogen-fixing bacteria and legumes involves the conversion of atmospheric nitrogen into which usable form?
सही उत्तर: क) Glucose
Nitrogen-fixing bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), a biologically available form that plants can then utilize. Glucose, ethanol, and carbon dioxide do not represent the products of this symbiotic relationship.

Which of the following adaptations allows earthworms to thrive in their terrestrial environment?
सही उत्तर: ख) Development of a thick epidermis with mucus glands
Earthworms have a specialized epidermis with mucus glands and, crucially, a thickened cuticle containing mucus that helps prevent water loss - a key adaptation for terrestrial life. Scales provide protection in other environments.

The process of facilitated diffusion involves the assistance of which molecule to move substances across a cell membrane?
सही उत्तर: ख) channel proteins
Channel proteins, specifically transmembrane channels, provide a pathway for molecules to cross the cell membrane down their concentration gradient. ATP synthase is involved in active transport, phospholipids form the basic structure of the membrane, and receptor proteins are involved in signal transduction.

The process of formation of male gametes (sperm) from diploid germ cells is called: (a) Meiosis (b) Mitosis (c) Fertilization (d) Cloning
सही उत्तर: क) (a) Meiosis
The correct answer is (a) Meiosis. Meiosis is the type of cell division that reduces the chromosome number by half and produces haploid gametes like sperm. Option (b) - Mitosis – results in identical cells, not gamete formation. Options (c) – Fertilization – is the fusion of gametes, and (d) – Cloning – involves creating genetically identical copies.
