Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
Answer:
The chemical components, which are utilized to eradicate or eliminate pathogenic microbes are known as chemical disinfectants. These comprise sodium hypochlorite, chlorine, bromine, hydrogen peroxide, chloramines, and others.
Traditionally, the chemical disinfectants are usually compared with phenol as phenol was the first or the foremost used chemical agent for the purpose.
Answer: It helps to regulate circadian rhythm
Exposure to natural light during the day helps regulate the circadian
rhythm, which improves sleep pattern. The term circadian rhythm refers to our
biochemical, physiological and behavioral processes in approximately 1 full day
cycle. Circadian rhythm plays an
important role in
controlling when we fall asleep and when we wake up.
During day light, the secretion of melatonin or sleep hormone is
suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime,
melanopsin stimulates the release of melatonin to signal sleeping time. Therefore,
this hormone works the entire day and has direct effect on the circadian
rhythm, which acts as a regulator of our biological clock.
Yes because you have a smaller population
Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. During transpiration water evaporates from the leaves and draws water from the roots.
