Describe the first three life cycle stages of a frog.​
Masteriza [31]

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.

Lapatulllka [165]

Answer:

Chromosomes

Explanation:

Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.

Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
