Scientists always look for patterns.
When analyzing data, this is essential to finding out important information.
To answer this we need to remember how proteins are structured, the primary structure is just the polypeptide chain, secondary there is a certain folding level alpha-helix and folded beta-sheet, then is the tertiary structure that comes from a single polypeptide chain and is formed by secondary structures, finally, there is the quaternary structure where several polypeptide chains are involved as well as tertiary structures are folded together. Therefore taking this into consideration we can say that the correct answer is option two.
Answer:
1. time the car stopped is at 0.7-0.8 hours.
2. time greatest velocity: 0.2 - 0.4 hours.
3. greatest velocity: 60.0.
4. car accelerating at 0.4 - 0.7
5. fast car going at 1.0: 40.0
6. acceleration at 0.9: 20.0

Answer:
D) All of the above are true.
Explanation:
Wetlands are the regions of land which are covered by water. The water can be fresh water, Saltish water or between these two. Low-lying areas of rivers or oceans, ponds, lakes and marshes, all fall under wetlands.
- Wetlands are extremely important for the life on earth because of immense number of services they provide to humans, wildlife and fish. They are more productive region than coral reefs and rain forests.
- They have an important role in protecting the shores from the strong action of waves that can cause floods. They also help in trapping sediments and thus lowering the losses due to soil erosion. This makes option A true.
- They provide habitat and food source to wide array of organisms such as fish and wildlife therefore option B is also true.
- They also help in the controlling of pollution because they clean or filter sediment from runoff water which ultimately helps in preventing mud clogging in water reservoirs such as lakes. Therefore, they have a cleansing or filtration action and this makes option C true.
Hence, D is the best option.

Answer:
The correct answer is villi.
Explanation:
The carbohydrates consumed by human beings are further dissociated into its mono forms, that is, fructose, glucose, and galactose. Of these monosaccharides, about 80% is glucose, which gets absorbed with the assistance of absorptive cells in the small intestine. In the walls of the small intestine, the food after digestion is passed into the blood vessels via the process of diffusion.
The mucosa or the inner wall of the small intestine is enveloped by finger-like tissues known as villi that further comprise microscopic finger-like outcrops called microvilli. These villi and microvilli enhances absorption of nutrients as they increase the surface area of the small intestine. Thus, the absorption of glucose within the small intestine is enhanced by the presence of villi.
