C Correct answer
Explanation

  • The loss of trees, which anchor the soil with their roots, causes widespread erosion throughout the tropics.
  • Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.
  • Maize is a wind-pollinating crop and is able to cross-pollinate in neighboring fields.
  • In legumes and a few other plants, the bacteria live in small growths on the roots called nodules. Within these nodules, nitrogen fixation is done by the bacteria, and the NH3 they produce is absorbed by the plant. Nitrogen fixation by legumes is a partnership between a bacterium and a plant.

So, the correct answer is 'A - 3, B - 1, C - 2, D - 4'.

Organisms using protonephridia for excretion are...

  1. flatworms rotifers ,earthworm

  2. amphioxus,cockroach, prawn

  3. planaria ,cephalochordates ,rotifers

  4. rotifers cephalordates ,Annelids
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms(except the turbellarian order Acoela), rotifers and nemerteans; these are the simplest animals to have a dedicated excretory system. Bundles of flame cells are called protonephridia. So the correct option is 'Flatworm rotifers, earthworm’.

B Correct answer
Explanation

Growth by mass is a feature but not a defining property (as non-living things also grow by mass). Potato and brinjal are different species. Biological names are derived from Latin. Hominidae is the family of humans, and botanical gardens are collections of living plants.
