List-I List-II
A. Deforestation 1. Vacuoles
B. Cellular structure 2. Maize
C. Cross pollination 3. Soil erosion
D. Nitrogen fixation 4. Legumes
  1. A - 4, B - 1, C - 2, D - 3

  2. A - 1, B - 2, C - 4, D - 3

  3. A - 3, B - 1, C - 2, D - 4

  4. A - 2, B - 3, C - 4, D - 1


Correct Option: C
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'.

The resinous substance, shellac is obtained from

  1. An insect

  2. The bark of a tree

  3. Crude oil

  4. Distillation of wood


Correct Option: A
Explanation:
Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes (pictured) and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze, and wood finish.

So, the correct answer is 'An insect'.

Organisms using protonephridia for excretion are...

  1. flatworms rotifers ,earthworm

  2. amphioxus,cockroach, prawn

  3. planaria ,cephalochordates ,rotifers

  4. rotifers cephalordates ,Annelids


Correct Option: A
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’.

Professor Birbal Sahani discovered 100 million years old fossil plant from fossil forest at Rajmahal Hills, Bihar. This plant was

  1. Rhynia

  2. Horneophyton

  3. Williamsonia

  4. Red alga


Correct Option: C
Explanation:

In 1932 Palaeontologica Indica, Birbal Sahni added an account of the Bennettitalean plant that he named Williamsonia sewardi.

So, the correct answer is 'Williamsonia'.

Cellular organization has ______ stages

  1. $3$

  2. $5$

  3. $2$

  4. $4$


Correct Option: B
Explanation:

The components of the cell and the arrangement of the individual parts within the cell form the cellular organisation.

So, the correct option is '5'.

A living organism can be unexceptionally differentained from a non-living thing on the basis of its ability for....

  1. Reproduction

  2. Growth and movement

  3. Responsiveness to touch

  4. Interaction with environment and progressive evolution


Correct Option: C
Explanation:
Reproduction can or cannot be criteria because the childless couple is there who are living. evolution need not always be progressive. Growth is also shown in a deposition if materials and movement are exhibited by nonliving things.
So, the correct option is 'Responsiveness to touch'.
