Laboratory mice are similar but not identical to each other. (apex)
The correct answer is (A)
Burning of wood is a chemical change as new substance is formed during the burning of wood which is not reversible.
Now, what happened during the burning of wood?
In the case of burning wood, stored potential energy( in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion that requires oxygen. We can also say that combustion is change of potential chemical energy into kinetic energy in the form of heat.
Answer:
density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
1A): Fats are =====> <u>Solid at Room temperature</u>
1B): Oils are =====> Liquid at Room Temperature
2A): Lipids ====> <u>Are a group of organic compounds, that include fats, oils, waxes and related substances. Lipids are composed of carbon and hydrogen, and oxygen, but there is no definite ratio of hydrogen to oxygen atoms lipids as there is in carbohydrates. Simple lipids, which are the most common type, are made up of three fatty acids molecules, and glycerol molecule.</u>
2B): Carbohydrates =====> <u>Are organic compounds composed of carbon, and hydrogen, and oxygen. The proportion of hydrogen atoms to oxygen atoms in carbohydrates is the same as in water; Two hydrogens to one oxygen. There are three basic types of carbohydrates. Monosaccharides, disaccharides, and polysaccharides.</u>
3): <u>A positive control ===> s</u><u>hould give the desired outcome of the experiment, provided that all the reagents and equipment are functioning properly. For example, if your experiment results in the ability of bacteria to grow on a petri plate containing antibiotic, your positive control will be bacteria that are known to carry the appropriate drug resistance marker. Even if none of your experimental bacteria grow, as long as there is growth of the positive control you know that growth was possible. </u>
3B): A Positive Control =====> <u>should be designed to not give the desired outcome of the experiment. In the example above, bacteria which do not carry a drug resistance marker should not be able to grow on a petri plate containing antibiotic. If growth is observed, it is a red flag that something is wrong with the experiment.</u>
Hope that helps!!! : )
So that they don't explode.
AKA with a thing called osmosis (transportation of water through cells.)
