The largest cell in the human body is the ovum, the female sex cell. The largest cell in the world is an ostrich’s egg.
Answer: 3.
Explanation:
The concept is based on sexual imprinting which results from selection for recognition of conspecifics.
Sexual imprinting is the mechanism by which a young animal discovers the properties of a desired mate. Male zebra finches, for example, tend to favor mates with the presence of the female bird rearing them, rather than that of the birth parent when they're special.
A female zebra finch select a male that resembels her father with a red feather taped to his head for reprodcution because there are sufficient opportunity of sexual imprinting.
Hence, the correct option is 3.

Answer:
True
Explanation:
Earlier it was believed by researchers that sleep is not a good thing as it does not allow an organism to stay alert all the time due to which there are high chances of such organism being consumed by other organism. However, with the discovery of theory of evolution, it is now believed that sleep has also evolved. Its evolution allows an organism to save energy and conserve it.
Evolved sleep has helped decrease synaptic strength which allows a person to preserve memories and function well during the day time. REM sleep in the early morning makes brain metabolically active even while sleeping and hence, dream comes.
