Answer:
Nucleotide
Explanation:
A Nucleotide is made out of a phosphate group, 5-ringed sugar, and a nitrogenous base, all of which are present in the image. Here the nitrogenous base appears to be adenine so it is the nucleotide derived from adenine.
It has to do with vibrations being able to travel through the air when the tuning fork was struck the vibrations made the air around it vibrate as well and when the vibrating fork got near the string the vibrating air made the string vibrate as well.
From the list provided the eco-friendly activities are recycling materials, growing trees, burying organic matter and using fewer disposables. Recycling materials ensures that less refuse is available to become trash. Planting trees prevents and remedies soil erosion. Using fewer disposables ensures that less refuse enters the environment. Filling landfills, cutting trees and burning fossil fuels are all non eco-friendly practices.
The genetic code is the set of rules by which information encoded in genetic material (DNA).
Because bile contains salts and digestive compounds and lipase is a digestive enzyme, you might create a simple qualitative experiment to test the action of bile and lipase. Bile is first used to emulsify and break down food entering the small intestine, and lipase is used afterwards by the pancreas to break down fats. With this information, I suggest this experiment:
1) Label 4 test tubes A, B, C, and D. Divide the fat solution equally into the 4 tubes.
2) In tube B, add an x amount (but not the whole volume) of the bile solution.
3) in tube C, add a y amount (but not the whole volume) of lipase solution.
4) in tube D, add the x amount of bile and the y amount of lipase solution.
5) Swirl/mix until everything looks homogenized/settled.
6) tube A is your control. Compare the 3 other tubes to it and write observations. You should be able to make conclusions about the role of bile in digesting a fatty solution, and the extent of digestion with and without the additional lipase.
Hope this is helpful!~ There are certainly many other possible experiments.
