I think an example would be, Humans are larger than they were 100 years ago. This is not a genetic characteristic .Phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior and products of behavior. The Genotype on the other hand is the genetic make up of an organism.
Answer:
The effectiveness of chemical disinfectants has historically been compared to phenol.
Explanation:
The effectiveness of a disinfectant or antiseptic can be determined in a number of ways. Historically, a chemical agent’s effectiveness was often compared with that of phenol, the first chemical agent used by Joseph Lister. In 1903, British chemists Samuel Rideal (1863–1929) and J. T. Ainslie Walker (1868–1930) established a protocol to compare the effectiveness of a variety of chemicals with that of phenol, using as their test organisms Staphylococcus aureus (a gram-positive bacterium) and Salmonella enterica serovar Typhi (a gram-negative bacterium). They exposed the test bacteria to the antimicrobial chemical solutions diluted in water for 7.5 minutes. They then calculated a phenol coefficient for each chemical for each of the two bacteria tested. A phenol coefficient of 1.0 means that the chemical agent has about the same level of effectiveness as phenol. A chemical agent with a phenol coefficient of less than 1.0 is less effective than phenol. An example is formalin, with phenol coefficients of 0.3 (S. aureus) and 0.7 (S. enterica serovar Typhi). A chemical agent with a phenol coefficient greater than 1.0 is more effective than phenol, such as chloramine, with phenol coefficients of 133 and 100, respectively. Although the phenol coefficient was once a useful measure of effectiveness, it is no longer commonly used because the conditions and organisms used were arbitrarily chosen.
The answer is C. All of these different environments require a wider variety of adaptations.
Answer:
<h2>
The scorpions</h2>
Explanation:
If you look the scorpion would only eat the insects so if the insects were removed then the scorpions wouldn't have any food and would die out causing extinction.

Dextromethorphan. This is a drug that is used for this purpose and is considered an anti-tussive.
