SOLUTION

Egg: The egg cases look like capsules and are generally brown in colour and, about 6-9 mm in length, depending upon the species.

Nymph: After 6-7 weeks, the egg hatches and the larva of the cockroach come out of it. The larva of a cockroach is called nymph. Nymphs are soft and white in colour but they turn hard and brown soon after coming out.  

Adult: The nymphs keep on growing as they feed, 9-13 months later; nymphs develop into fully grown cockroaches.

SOLUTION

Cockroaches undergo incomplete metamorphosis and have three life stages e.g. egg, nymphs and adult. Nymphs look a lot like an adult cockroach except that their not well developed like they do not have fully developed wings but after 9-13 months, these nymphs develop into fully grown cockroaches with strong legs, hard skin, wings and long antennae on their head.

SOLUTION

Cockroaches belongs to the group of insects that are one of the oldest species found on the earth. They are also known as roaches. There are about more than 4,000 species of cockroaches found worldwide. The four major species of the cockroaches are: German, American, Oriental and Brown-banded cockroaches.

Arboreal animals eat fruits, nuts, bark, and other parts of trees. Sometimes they eat insects like ants and bird eggs. Monkeys who live in towns and cities, eat parched gram also. They almost eats every thing which a man eats.

SOLUTION

Many arboreal animals have elongated tail that allow them to swing efficiently from branch to branch. Many monkey species have this adaptation. Long tails help them to  grasp branches of trees easily. Spider monkeys and chameleons are examples of animals that use their tails to help move and stabilize themselves in the tree canopy.

SOLUTION

Amphibians spend their lives in the water and on land. All amphibians begin their life in water with gills and tails.  As they grow, they develop lungs and legs for their life on land. There are more than 4,000 different kinds of amphibians. Some examples of amphibians are frogs, toads, salamanders, newts, and caecilians or blindworms.

SOLUTION

An aquatic animal is an animal which lives in water for most or all of its life. It may breathe air or extract its oxygen from that dissolved in water through specialised organs called gills. Some common examples of aquatic animals are fish, crab, octopus, seahorse, and turtle.

SOLUTION

Some birds also live in water such as ducks, geese and swans. They are called water birds. They have webbed feet to help them swim in water.

SOLUTION

All birds have feathers.

1. Feathers provide protection (from weather and injury).
2. Feathers serve as insulation from cold and heat.
3. Feathers help birds attract mates.

SOLUTION

Birds are animals that can travel large distances during migration. Not all birds migrate, but the majority of birds do. They do this for various reasons, for example, to find a more abundant source of food or a better climate.

SOLUTION

Some birds like Siberian Cranes live in very cold places. So, during winters, they fly for thousands of kilometres to warmer places in search of food and shelter and return after winters. This activity is called migration.

SOLUTION

There are some birds whose ears cannot be seen like pigeon, crow, sparrow, hen and duck. Ears are tiny holes that are hidden under their feathers.

SOLUTION

Aerial animals have streamlined body to fly easily in the air. Their body is covered with feathers to keep them warm during the flight.

SOLUTION

a. First of all, butterflies lay eggs.

b. Egg converts into a caterpillar.

c. Then, caterpillar converts into pupa.

d. The young butterfly emerges out of the pupa.

e. Gradually, it changes into an adult butterfly.

SOLUTION

Insects smell and feel through feelers on their head called Antennae and many insects have a hard outer layer which is called as Chitin.

SOLUTION

Insects have six legs and their body is divided into three parts: head, thorax and abdomen. They may have 2-4 wings.

SOLUTION

a. Disagree

b. Agree

SOLUTION

Amphibians use their skin and gills to breathe in water while they use their lungs to breathe on land.

SOLUTION

Animals majorly reproduce either by laying eggs or by giving birth to a new individual.

There are three types of animals on the basis of reproduction  -

1. Oviparous- Animals that lay eggs, with little or no other embryonic development within the mother.

2. Ovoviviparous- Animals develop within eggs that remain in the mother's body up until they hatch or are about to hatch.

3. Viviparous- Animals that give birth to offspring that develops within the mother's body.

SOLUTION

Birds migrate to-

• Move from areas of low resources of food and nesting locations to areas of high resources.
• Escape from the cold environment to warmer places so that they can survive and get sufficient food, water and shelter.

The two migratory bird are-

• Siberian Crane
• Greater Flamingo

SOLUTION

The characteristic of an insect, which enables it to fly are-

• As insects are small and do not weigh a lot so, this feature helps them in flying.
• They have one or two sets of wings. The wings are thin and flat which they flap continuously for forward movement.
• Insect wings are attached to specialized flight muscles which helps in rapid wing movement.

SOLUTION

The characteristics of a bird, which enables it to fly are-

• It has got a Streamlined body shape which cuts the air making the flight easier.
• Bones of the birds are hollow thus making them light weight which aids flight.
• Birds have powerful muscles which are also known as Flight Muscles.
• Birds have strong Heart & Lungs for proper blood and oxygen supply.
