Answer 1

Answer:

a)grass hopper characteristics

Grasshoppers usually are a shade of brown, green or black. They have large hind legs that help them jump long distances, hence their name. Adult grasshoppers also have two sets of wings, with the forewings being slender and the hindwings large.

b) bath sponge

Bath sponges are made of calcereous or siliceous spicules, and they are therefore soft to the touch. Most of the bath sponges are Demospongiae (2). Porifera means pore-bearing. Sponges are covered with tiny pores on the outside called ostia.

c) jelly fish

Some jellyfish are clear, but others are vibrant colours of pink, yellow, blue and purple. They can be bioluminescent, too, which means they produce their own light! Jellyfish have no brain, heart, bones or eyes. They are made up of a smooth, bag-like body and tentacles armed with tiny, stinging cells.

d) frog

In general, frogs have protruding eyes, no tail, and strong, webbed hind feet that are adapted for leaping and swimming. They also possess smooth, moist skins. Many are predominantly aquatic, but some live on land, in burrows, or in trees. A number depart from the typical form.

e) Lizard

Four limbs.

External ears.

Movable eyelids.

A short neck.

A long tail, which they can shed in order to escape from predators.

They eat insects.

f) elephant

Elephants are the largest living land animals, characterized by their long trunk (elongated upper lip and nose), columnar legs, ivory tusks, and huge head with wide flat ears. ...

Elephants are herbivores: they eat a range of plants, including grasses, fruit, and roots.

g) penguin

Its body is fusiform (tapered at both ends) and streamlined. A penguin has a large head, short neck, and elongated body. The tail is short, stiff, and wedge-shaped. The legs and webbed feet are set far back on the body, which gives penguins their upright posture on land.
