One-celled organisms can respond to stimuli.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Response to stimuli also known as sensitivity is shown by all the living organisms whether it is unicellular or multicellular. This is essential for one-celled organisms for their survival. For example, if a unicellular organism is exposed to a chemical, it will react either by producing another chemical or by moving away from the stimulus to survive. 

Thus, the correct answer is option A.

The term 'taxon' is used for __________________.

  1. The ranks of species and genus

  2. The ranks up to phylum

  3. The species epithet only

  4. Any rank of taxonomic hierarchy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Taxon is a unit of classification which may represent any level of grouping of organisms based on certain easily observable common characteristics. Mayr $(1964)$ has defined taxon to be a taxonomic group of any rank that is sufficiently distinct to be worthy of being assigned to a definite category.

Which one of the following constitutes the two best reasons for .distinguishing the living from the non-living?

  1. Reproduction and locomotion

  2. Respiration and excertion

  3. Growth and locomotion

  4. Irritability and locomotion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Respiration and excretion are two exclusive properties of living being ,whereas locomotion can be seen in non living organism owing to certain factors liike wind, water etc. So, the correct option is B. ( Respiration and excertion )

Metabolism is 
A) Total of all the chemical reactions accuring in the body of organisms
B) Observed even outside the body in a test tube
C) Not observed in non-living objects

  1. A only

  2. C only

  3. AC only

  4. ABC
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A sequence of biochemical reactions occur in the living organisms is called Metabolism. it is the life-sustaining process occurs in the living organism and always takes place in the living organism. Metabolism can be demonstrated out side the living body. They do not occur in the non living body.

So, the correct option is 'ABC'.

Match:

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
Reveal answer Fill a bubble to check yourself
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'.
