Who is Darwin? Please be more specific.
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!!! : )
Answer:
C. Darwin's explanation of natural selection
Explanation:
<em>According to Darwin, natural selection selects for traits that are more adaptable to an environment and individuals with such traits tend to reproduce and contribute more offspring to successive generations.</em>
As the environment keeps changing, organisms keep trying to adapt to the changes. Those who are able to adapt flourish more within the environment while the weak ones gradually get replaced in the population.
In the case of sickle cell heterozygosity and malaria; individuals that are heterozygous for the sickle cell trait are generally known to be less prone to malaria. Hence, this becomes a selection advantage over individuals with other genotype forms. Heterozygous individuals thus contribute more offspring into the population than other genotype forms according to natural selection law.
The correct answer is C.
According to the hierarchy it is the Genus
