Answer:
An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
Continuously facing towards the east also helps the flowers to heat up quickly. This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant's interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
Answer:
plants deprived of light will lose their colour and die
Explanation:
the lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to treat a green colour
Answer:
It helps organisms survive.
Explanation:
To elaborate, adaptive traits and behavior is learned because of a necessity to <em>survive</em>.
A good example might be vaccinations and your immune system. Your body needs exposure to a pathogen to learn what it does, then adapts to fight off the pathogen. It adapts to survive.
In a constantly changing world, if you can't adapt, you simply won't survive long enough.
Sexual reproduction offers genetic variation, as the offspring are a combination of 2 sets of genes opposed to one. This ultimately leads to evolution and the adaption to changing environments :)
