Nutritive substance for cocoon secreted by

  1. Mucous cells

  2. Albuminous cells

  3. Yellow cells

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The clitellum plays an important role in reproduction. Its glands produce mucous which becomes a sheath containing nutritive material. The sheath slides forwards, collecting eggs and sperm from the genital openings of the worm. The sheath finally slides off from the head of the worm. As it separates from the worm, its ends are sealed. It now becomes a cocoon.

So, the correct option is 'Mucous cells'.

Multiple choice evs a treat for mosquito algae: benefits and harmful effects basics of algae types of microorganisms

Which of the following gives shelter to grow mosquito larva?

  1. Dark box

  2. Algae

  3. Fruits

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Most species of algae live in the water bodies like sea, lakes, ponds, etc. Even some unicellular green algae inhabit moist conditions on land, for example - tree trunks, moist soil surface, damp walls, wetlands, swamps, etc. Usually, the insect mosquito prefers stagnant water and damp environment for laying eggs. The eggs hatch and the larvae live in water until they transform into motile pupae, from which the adult mosquito emerges. Due to this, the algae serve as an excellent shelter for growing mosquitoes. Even mosquito larvae that need constant energy to grow, eat plankton, algae, fungi and other microbes present in their habitat. Therefore, algae not only harbor mosquito larvae but also feed those growing insects. So to keep the water bodies pleasant and beautiful, algae and weeds must be regularly removed from them; as they provide growing mosquitoes with housing, nutrition, and hideaway from predators.

Multiple choice evs a treat for mosquito algae: benefits and harmful effects basics of algae types of microorganisms

Which of the following helps in the breeding of mosquitoes?

  1. Algae growing in the pond

  2. Algae growing on the on wall

  3. Algae growing in the river

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Mosquitoes lay their eggs in standing water where the larvae hatch and feed before pupating and emerging as adults. The larvae come to the surface of the water to feed and breathe and then hide from predators under vegetation in your pond. Ponds can be an ideal breeding ground for mosquito larvae. The larva from the eggs feed on algae present in the pond.

So, the correct answer is 'A'.
