Answer : Option A
Explaination / Solution:
No Explaination.
Q2.
Match the following :
| Column A | Column B |
| a) Motor Neuron | i) carry impulse away from cyton |
| b) Axon | ii) carry impulse from receptor to CNS |
| c) Afferent Neuron | iii) carry impulse towards cyton |
| d) Dendrite | iv) carry impulse from CNS to effector |
Answer : Option C
Explaination / Solution:
Motor neuron carry impulse from CNS to effector. Axon carry impulse away from cyton. Afferent neuron carry impulse from receptor to CNS and dendrite carry impulsetowards cyton.

Q6. Which among the following transition metal has lowest melting point?
Answer : Option B
Explaination / Solution:
Zn has lowest melting point because it doesnot have any unpaired electrons.
Q7. If the ratio of change between the two variables is a constant then there will be
Answer : Option A

Answer : Option A
Explaination / Solution:
Per capita income or average income measures the average income earned perperson in a given area (city, region, country, etc.) in a specified year. It is calculated by dividing the area's total income by its total population.
Q9. In Ulothrix or Spirogyra, reduction division (meiosis) occurs at the time of
Answer : Option A
Explaination / Solution:
In Ulothrix/Spirogyra reduction division (meiosis) occurs at the time of zygospore germination. Plant body of Ulothrix and Spirogyra, is gametophytic (haploid), they produce zoogametes (n) which fuses to form zygosporic (2n) diploid, which is a resting spore. Onset of favourable condition zygospore undergoes reductional division, or meiosis to produce zoo- meiospores.
Q10. The ability of a living somatic nucleated cell to form the complete organism is called
Answer : Option D
Explaination / Solution:
Cellular Totipotency is the ability of a single cell to produce all cell types and to organise them into an entire organism when cultured in a suitable culture medium at appropriate temperature and aeration conditions. Spores and Zygote are examples of totipotent cells.
