The Earth is at the center Explanation: Aristotle first postulated that the Earth was round but maintained that all celestial bodies revolved around it.

To ascertain allele frequency, one must take into account the dominant and recessive alleles in a genotype.
According to the provided data, the following calculations yield the allele frequencies:
allele A = 100/300, allele B = 50/300, allele O = 150/300
Therefore, the frequency for allele A equals 0.33 or 33%, allele B equals 0.17 or 17%, and allele O equals 0.50 or 50%.

  

Answer:

The answer is A) Active transport involves moving substances against the concentration gradient.

Explanation:

Facilitated diffusion refers to the process where other molecules assist in the transport across the cellular membrane. This usually involves integral proteins that aid in moving a molecule. Since facilitated diffusion occurs from areas of higher concentration to lower concentration, it is considered a passive transport method.

In contrast, active transport refers to the process of moving molecules from a location of lower concentration to one of higher concentration, which requires energy to occur.

Answer:

A pendulum clock operates mechanically, depending on a pendulum that swings consistently; energy for the pendulum is supplied by a spring. On the other hand, a quartz clock depends on the precise, repetitive vibrations of a fine piece of quartz. These vibrations generate an electrical current that powers the electronic display.

Answer: C) Pepsin will probably NOT react with sugar glucose since it is an enzyme that breaks down protein. This is due to the specificity of the enzyme to its substrate, where pepsin only targets proteins and converts them into peptides. No matter where the reaction occurs, the enzyme's function is limited to its designated substrate. Therefore, reacting pepsin with glucose would yield no results.
