The answer to this question is the Pyers
patches. The Pyers patches are lymphatic tissues found through
the small intestines that have an important role in the immune system. Pyers
patches are also known as the aggregated lymphoid nodules that monitors and
prevents growth of bacteria in the intestine that is harmful in the intestines.
Wavelength light source is part of the control group for William’s experiment
<u>Explanation:</u>
Sir William wanted to conduct an experiment to observe how much heat passed through different colour filters of the sunlight. He directed sunlight to pass through the prism and observed vibgyor and measured the temperature. He found that the temperature increased from violet to red.
Then he was inquisitive to find the temperature beyond the red ray. That’s when he found the infrared rays which had higher temperature that was not to be seen through naked eyes. He performed experiments using the light source and found that the wavelength of light are not refracted in a particular pattern.
<span>Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.</span>
