Ans.33 Correct option is (b) Ultra-Violet Radiation

$\sf \colorbox{skyblue} {Explanation:}$

• Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The "ozone layer," approximately 6 through 30 miles above the Earth's surface, reduces the amount of harmful UV radiation reaching the Earth's surface.

Ans.34. Correct option is (a) Placenta

$\sf \colorbox{skyblue} {Explanation:}$

Waste products and carbon dioxide from the fetus are sent back through the umbilical cord and placenta to the mother's circulation to be eliminated.

Ans.36 Correct option is (d) Axon

$\sf \colorbox{skyblue} {Explanation:}$

• Thus, the impulse always flows from one axonal end of a neuron to another dendron head of a neuron. Therefore, conversion of electrical signal to a chemical signal occurs at the Axonal end.

Ans.37 Correct option is (d) Pollen grains

$\sf \colorbox{skyblue} {Explanation:}$

The part of the stamen where pollen is produced. It is a bilobed tetrasporangiate structure attached to the filament and a part of the stamen. A sepal is a unit of the calyx, the outermost whorl of the flowering plant. The sepal is the outer parts of the flower (often green and leaf-like) that enclose a developing bud. The ovule producing part of a flower is the pistil. The anthers on the flowers are an integral part of the flower’s structure that create the pollen.

• The anthers rise high from the flower’s centre on long filaments.

• Different flower species have varying numbers of anthers, but most have five to six anthers that circle the centre of the flower.

• Botanists call the filaments and anthers together the stamen of the flower.

• Anthers are grainy pods on the ends of the filaments that range in colour from light yellow to deep red.

Ans.38 Correct option is (c) 9:3:3:1

$\sf \colorbox{skyblue} {Explanation:}$

• Mendel observed that the F2 progeny of his dihybrid cross had a 9:3:3:1 ratio and produced nine plants with round, yellow seeds, three plants with round, green seeds, three plants with wrinkled, yellow seeds and one plant with wrinkled, green seeds.

Ans.39 Correct option is (C) X Chromosomes of a ovum

$\sf \colorbox{skyblue} {Explanation:}$

• Human males have a XY genotype and form two types of sperms carrying either X or Y sex chromosomes. A zygote formed by fusion of sperm with X and an egg cell results in a female child, whereas the fusion of a Y sperm leads to a male child.
