Why might the medical assistant opt to take a patients apical pulse rather than radial?
SpyIntel [72]
If the medical assistant noted irregularities in the heart rate when palpating the radial pulse, they would opt to take a patients apical pulse for a full minute to make sure they are accurately counting the number of heartbeats per minute.

During the process of photosynthesis,
TEA [102]

Answer:

d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds

Explanation:

Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.

During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.

The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.

When human DNA molecules and chimpanzee DNA molecules are heated to separate the two sides of the molecules from each other and
Sloan [31]

Answer:

B. Humans and chimpanzees share a relatively recent common ancestor.

Explanation:

Both the humans and Chimpanzees are the primates that are they belong to the same group called hominids and genus called Homo.

When the DNA sequences of the Chimpanzees and the Humans are sequenced and compared than they showed that 98% of the genome is similar.

In the given question, the single strands of the humans and the chimpanzees base-paired which showed that 98% of the nucleotide sequence is the same. The most possible reason for this similarity is that they both were evolved from the common ancestors and they diverged recently in the past.

Thus, Option-B is correct.
