Expert Solution

1. Option D is correct

Sexual reproduction is a mode of reproduction which generates far more variations in a population as compare to the asexual reproduction. If the environment is unstable and changing then the organisms with more variations would have more chances of survival due to natural selection. Since with changing environment some individuals might survive and reproduce.

Budding, fragmentation, parthenogenesis and vegetative reproduction are types of asexual reproduction due to less difference amongst the members of a population all may perish together with changing environment.

2. Option E is correct

Precipitation in an area is affected by the latitude, location relative to large mountains, elevation and distance from a large water body.

3. Option B is correct

Exoskeleton of insects is made up of a polysaccharide known as the chitin.

reptile scales, mammalian hair, bird feathers, claws, finger nails, hooves and horns are made up of keratin.

However, there is still considerable uncertainty about whether the Mediterranean diet is superior to a low-fat diet recommended by the American Heart Association. This study is the first to compare these two diets. The subjects, 605 survivors of a heart attack, were randomly...
