The part of the neuron that is usually myelinated and conducts impulses away from the cell body is the:
A. Axon
B. Synapse
C. Dendrite
D. Cell body

Correct Answer: Option A


Explanation:
The axon is a long, slender projection of the neuron that carries nerve impulses (action potentials) away from the soma to other neurons, muscles, or glands. Axons are often insulated by a myelin sheath. Dendrites receive signals, the cell body contains the nucleus, the synapse is the junction.

National parks and wildlife sanctuaries are examples of which type of conservation?
A. Cryopreservation
B. Tissue culture
C. In-situ conservation
D. Ex-situ conservation

Correct Answer: Option C


Explanation:
In-situ (on-site) conservation involves the conservation of species in their natural habitats. National parks, wildlife sanctuaries, and biosphere reserves are examples of in-situ conservation. Ex-situ (off-site) conservation involves taking endangered species out of their natural habitat and placing them in special settings like zoological parks, botanical gardens, and seed banks for conservation and breeding.
