d) None of these
12.) The living organisms …………………………………………………………………… self-replicate.
a) Cannot self-replicate
b) Partially self-replicate
c) Posteriorly self-replicate
d) Can self-replicate
Answers:
1.)
Solution: c) Unable to grow
Unable to grow the incorrect characteristic of living organism because all the living organisms can reproduce, grow and have ability to sense.
2.)
Solution: b) Cell
Cell is the type of division by which multicellular organisms or plants can grow. The process of cell division takes place continuously throughout their life span.
3.)
Solution: a) Mass of the organisms increases
Mass of the organisms increases when all the living organisms grow. Also, number of individuals increases during growth.
4.)
Solution: b) Regeneration
The Planaria is a flat worm and true regeneration is observed in the Planaria. Budding process is observed in the organisms like yeast and hydra.
5.)
Solution: d) A-q, B-p, C-r
Regeneration is observed in the flat worms, budding is observed in the hydra and spore formation is observed in the fungi. Hence, the correct match is A-q, B-p, C-r.
6.
Solution: d) Reproduction
Organisms are produced in the multicellular organisms with the help of reproduction. In the reproduction, the production of progeny occurs where it contains more or less similar characteristic of their parents.
7.)
Solution: b) Growth
Reproduction of the organisms such as amoeba or bacteria is synonymous with growth. Hence, an equivalent to increase in mass or cell number is called as Growth.
8.)
Solution: c) Mules
The mules require an even number of chromosomes and are sterile. Hence, mules do not reproduce.
9.)
Solution: c) Metabolism
In our body, the sum total of all the chemical reactions is known as metabolism. All the unicellular and multicellular organisms exhibit metabolism.
10.)
Solution: b) Consciousness
Among the living organisms, humans are only aware of themselves. So, consciousness is considered the defining property of living organisms.
11.)
Solution: a) Outside the body
All unicellular and multicellular organisms exhibit metabolism and this reactions can be demonstrated outside the body.
12.)
Solution: d) Can self-replicate
All the living organisms show reproduction, growth and response. Other than this, living organisms do have ability to self-replicate.
