Answer:
Cold
Explanation:
They can not survive in cold conditions
Answer:
Independent variable - time. Dependent variable - the distance moved by the bubble along the capillary tube. Control variables - temperature, air flow or draughts, adequate supply of water.
Wind power:
Advantages:
-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.
-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.
-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.
Disadvantages:
-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.
-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.
-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
Fats, oil and cholesterol are all types of lipids. This statement is absolutely true. Lipids are considered as fatty acids. And fats are types of fatty acid as well as the cholesterol and oil. Usually lipids are found on any food that has oils.
Answer:
All enzymes are mostly protein, but many are only protein. These enzymes are known as simple enzymes. Enzymes that contain other things, “complex enzymes,” are called holoenzymes. A holoenzyme has two parts. The protein part is called the apoenzyme.
The enzyme substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate. ... The substrate causes a conformational change, or shape change, when the substrate enters the active site. The active site is the area of the enzyme capable of forming weak bonds with the substrate.
Enzymes are protein molecules in cells which work as biological catalysts. Enzymes speed up chemical reactions in the body, but do not get used up in the process, therefore can be used over and over again. Almost all biochemical reactions in living things need enzymes. ... The study of enzymes is called enzymology.
