Question

A change in form in the life cycle of animals​

Answer 1

Answer:

hi

Explanation:

Some animals change dramatically in structure and function during their life cycle in a process called metamorphosis.

Answer 2

Answer:

GRADE-LEVEL EXPECTATIONS:

1. Plants and animals have life cycles that include a predictable sequence of

stages: they begin life, develop into adults, reproduce and eventually die.

Plants and animals produce offspring of their own kind. Offspring closely

resemble their parents, but individuals vary in appearance and behavior.

2. Animals are either born alive (for example, humans, dogs and cows) or

hatched from eggs (for example, chickens, sea turtles or crocodiles).

3. Animals change throughout their lives. Many animals begin life as smaller,

less capable forms of the adult. As they develop, they grow larger and become

more independent (for example, humans or robins).

4. Some animals change dramatically in structure and function during their life

cycle in a process called metamorphosis.

5. Frogs are amphibians that undergo metamorphosis during their life cycle. As

they grow, frogs develop different structures that help them meet their basic

needs in water and then on land:

a. Tadpoles hatch from eggs, live in water, breathe using gills, and swim

using a tail. As they metamorphose into frogs, tadpoles lose their

gills and their tails.

b. Adult frogs live on land and in water. They breathe air using lungs

and develop webbed feet and hinged legs for swimming in water and

hopping on land. After a female frog mates, she lays her eggs, and the

cycle begins again.

6. Butterflies are insects that undergo metamorphosis during their life cycle. As

they go through egg, larva, pupa and adult stages, butterflies develop

different structures that help them meet their basic needs in very different

ways:

a. Caterpillars hatch from eggs, live on plants, get food by chewing

leaves and move about using legs. As they metamorphose into

butterflies inside a chrysalis, they develop wings, antennae and

different mouth parts.

b. Butterflies live on land and in the air. They get food by sucking

nectar from flowers and move around primarily using wings to fly.

After a female butterfly mates, she searches for the proper host plant

to lay her eggs, and the cycle begins again.

7. Comparing the life cycle stages of different organisms shows how they are

alike in some ways and unique in other ways.
