Answer: The correct answer is as follows:
Stage 1) Egg - Frogs begin their life as fertilized eggs. A typical female frog can lay thousands of eggs, depending on the species. In the pond, the eggs float on the water in clusters until they hatch in 2-3 weeks.
Stage 2) Larva (tadpole) - During the tadpole stage, the frogs eat, grow and develop into froglets (with four legs) through a process called metamorphosis. As tadpoles, they rely on rudimentary gills, mouths, and tails for swimming. The tadpole's diet includes other frog eggs, bugs, mosquito larvae, and other dead insects. As their four legs and external respiration develops, the froglet is almost ready to leave the water.
Stage 3) Adult - At around 12 weeks of age, the frog has reached maturity as an adult and is ready to explore dry land. With its gills and tail totally absorbed back into the body, the frog remains an amphibian but spends most of its time out of the water. As an adult, the frog uses its sticky tongue to capture and eat insects, snails, slugs, and worms. They return to the water to lay new eggs and the cycle of life repeats.
Explanation:
False only underwater animals have gills
The convection is defined as the heat transferred in a liquid or a gas as a result of the actual motion of heated particles within it . If this movement is due to the effect of gravitation, due to differences in density, it is called natural convection.
Explanation:
1. Barr body is a drumstick-like structure of dense, coiled chromatin that appears normally in female's buccal cells and neutrophils. It represents the inactive X-chromosome (Females have two X-chromosomes. Only one is active.)
2. Liver cells are somatic, not sex cells and are thus diploid.
