First Final Question of Biology 11 - Animal Kingdom

ROUNDWORM 

are parasites that can infect people. They usually live in the intestines. There are different kinds of worms that 

can cause infection, and they can range in length from 1 millimeter to 1 meter. Most often, eggs or larvae live in 

the soil and get into the body when you get them on your hands and then touch your mouth. Some can also get 

into the body through the skin. 

Like other parasitic diseases, roundworm infections happen more often in warm, tropical climates. Ascariasis is 

the most common roundworm infection, and affects as many as 1 billion people worldwide.

EARTHWORM

An earthworm is a tube-shaped, segmented animal commonly found living in soil, that feeds on live and dead organic matter. Its digestive system runs through the length of its body. It conducts respiration through its skin. An earthworm has a double transport system

GRASSHOPPER 

Grasshoppers have antennae that are generally shorter than their body and short ovipositors. They also have pinchers or mandibles that cut and tear off food. Those species that make easily heard noises usually do so by rubbing the hind femurs against the forewings or abdomen

GRASSFROG

These smooth-skinned frogs can grow to an average weight of 22.7 grams with colours varying from gray to green, brown, yellow, or red and may be covered in blotches. Males are usually smaller and darker than females and have nupital pads on their first fingers to help hold on to the female during mating. The Grass Frog's underbelly are white or yellow often with speckles.

   

STARFISH

About 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000 m 

(20,000 ft) below the surface.
