Forceps should be used because directly touching the substance and dropping it into the acid with your hands can cause harm to yourself, and it can also prevent contamination of the substance.
Answer: The answer is natural selection
Explanation:
Natural selection explains how certain desirable traits like;
- shape of the beaks of Darwin's finches: to help them feed more easily
- industrial melanism to raise a population of dark-coloured organisms to evolve from pre-existing light coloured ones in industrial areas where the surrondings are blackened with soot;
are favored over LESS DESIRABLE TRAITS, resulting in organisms that are most suited/adapted to thrive in an environment, which is evolutionary change
The right option is; orbital period
T stands for orbital period.
Orbital period is the time a certain astronomical object such as planets takes to complete one orbit (360° revolution) around another object such as sun or stars. Orbital period is expressed in different units of time, usually in years, days or hours.
Answer:
The correct answer is "qualitative, discrete".
Explanation:
A qualitative or discrete trait is defined as a characteristic that have no intermediate features, and is often the result of genetic alleles at a single locus. For instance, if the form the seeds of pea could be either round or wrinkled, but not with intermediate forms. This is the case of the fly that has white or red eyes, but does not have pink eyes or other colors in between.
