Answer:
Testing positive for HIV means a high chance of death and a good chance of lower reproduction rates. But some people are immune to HIV, which makes them more evolutionarily fit, likely to live longer, likely to reproduce more, which would increase the frequency of the immune allele in the population. Over time, this increase in frequency of the gene that causes immunity could spread across the human race and cause it to evolve.

The correct answer is option B. Wind-pollinated plants rely on large quantities of pollen grains.
The plants, which pollinate by wind spend less energy in creating attractive structures to attract pollinators, instead they produce many pollen grains, which are light and easy to carry by winds. the pollens are usually dry.
The angiosperm mostly rely on animal pollinator and they have large colorful flowers, which produce nectar to attract the insects or other animals.
Answer:
Explanation:
sucrose — common table sugar = glucose + fructose. lactose — major sugar in milk = glucose + galactose. maltose — product of starch digestion = glucose + glucose + glucose
