A green potted plant is kept in darkness for 48 hours before a starch test is done. The purpose is to:
सही उत्तर: क) Remove the stored starch from the leaves
Keeping a plant in darkness destarches the leaves, so any starch found later must come from photosynthesis during the experiment. Chlorophyll is not increased by darkness.

A patient's pancreas does not produce enough insulin. The disease likely to develop is:

A cell with 46 chromosomes divides by mitosis. Each daughter cell will have:
सही उत्तर: ख) 46 chromosomes
Mitosis produces two daughter cells identical to the parent, each with 46 chromosomes. Halving to 23 happens only in meiosis.

-
A human body cell has 46 chromosomes. The number of chromosomes in a human sperm cell is:
सही उत्तर: घ) 23
Gametes form by meiosis, which halves the chromosome number, giving 23. Fertilisation restores the number to 46.

In a food chain, producers trap 10000 J of energy. According to the 10% law, the energy available to tertiary consumers is:
सही उत्तर: क) 10 J
Energy passes 10% at each step: producers 10000 → primary 1000 → secondary 100 → tertiary 10 J. 100 J is what secondary consumers receive.

In humans, the probability that a newborn baby will be a boy is:
सही उत्तर: ख) 50%
The mother gives X; the father gives X or Y with equal chance, so XY (boy) has a probability of 1/2. The sex of the child is therefore decided by the father's sperm.

In Mendel's dihybrid cross, the phenotypic ratio in the F₂ generation is:
सही उत्तर: ग) 9 : 3 : 3 : 1
Crossing two dihybrids (e.g., RrYy × RrYy) gives four phenotypes in 9 : 3 : 3 : 1. 1 : 1 : 1 : 1 is the ratio of a dihybrid test cross.

A heterozygous tall pea plant (Tt) is crossed with a dwarf plant (tt). The percentage of dwarf offspring expected is:
सही उत्तर: ग) 50%
Tt × tt gives Tt and tt in equal numbers, so 50% are dwarf. This is a test cross; 25% dwarf is from Tt × Tt.

-
A heterozygous tall pea plant (Tt) is crossed with another heterozygous tall plant (Tt). The phenotypic ratio of tall to dwarf offspring is:
सही उत्तर: घ) 3 : 1
Tt × Tt gives TT, Tt, Tt, tt; three are tall and one is dwarf. 1 : 2 : 1 is the genotypic ratio of the same cross.
