D Plica semimularis is found in eyes of frog. The plica semimularis is the thin upper part of the fold of mucous membrane in the supratonsillar fossa that reaches across between the two arches. - A separate fold is called the plicatriangularis which runs inforoposteriorly from the posterior surface of the platoglossal arch to cover the inferior portion of the tonsil.

How do you differentiate a frog from a toad?
1 Frog has no exoskeleton but toad has scales.
2 Frog respires through lungs but toad respires through skin
3 Frog has a tail but toad has no tail.
4 Frog has no parotid glands but toad has a pair of parotid glands.
Explanation:
D Frog have long legscompared to their head and bodywhich are made for jupming. Toadson the other handhave much shorter legs and prefer to crawl rather than hop. Frogs have smoothsomewhat slimy skin. Toads have drywarty skin. Frog has no parotid glands but toad has a pair of parotid glands behind the tympana.

Acoelus vertebrae in frog is
1 \(5^{\text {th }}\) vertebrae
2 atlas vertebrae
3 \(8^{\text {th }}\) vertebrae
4 none of these
Explanation:
B Acoelus vertebrae in frog is atlas vertebrae. Acoelous-Type of vertebrae found in most mammals in which the ends of the centrum are flat and the vertebrae are separated by an intervertebral disc.

In frog chromosome number is reduced half
1 when 2 nd polar body is separated
2 when 2nd polar body is divided
3 when 3rd polar body is separated
4 when 1st polar body is separated
Explanation:
D In frog the number of chromosomes is halved when the first polar body separates. The process of oogenesis occur as meiosis I and meiosis II. In meiosis Ithe diploid primary oocyte divides into two unequal haploid daughter cells known as the secondary oocyte and first polar body.
