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.

Julli [10]

A population of frogs with slightly different coloring is an example of microevolution. Microevolution is the changes in the gene pool of a population that can be measured and observed in short periods of time within a population. Microevolution can take place in several ways such as gene flow, genetic drift, mutation and selection.

What should you do if you need to leave the laboratory temporarily in the middle of your work?
kondor19780726 [428]

While leaving the laboratory temporarily in the middle of your work remove your lab coat and gloves.

<h3>Laboratory safety:</h3>

Washing your hands is the final thing you should do before leaving the lab after an experiment. Since most chemicals are somewhat harmful, wash your hands before you leave. After taking the necessary measures, inform the teacher.

With its risky processes, hazardous chemicals, and fire threats, the science laboratory is inherently unsafe. Avoid coming into contact with chemicals directly. Never taste, smell, or inhale lab chemicals. After taking off your gloves and before leaving the work area, wash your hands and arms thoroughly with soap and water. In a laboratory, never consume food or liquids, chew gum or tobacco, light up, or use cosmetics. These fundamental safety offer guidance on conduct, cleanliness, and safety to prevent laboratory mishaps.

1. Key Concept List the
Ipatiy [6.2K]
<h2>DNA </h2>

Explanation:    

1) Experiment done by Griffith:

  • Griffith used two related strains of bacteria, known as R and S
  • R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse whereas mice injected with live S bacteria developed pneumonia and died
  • Griffith tried injecting mice with heat-killed S bacteria (that is, S bacteria that had been heated to high temperatures, causing the cells to die), the heat-killed S bacteria did not cause disease in mice
  • When harmless R bacteria were combined with harmless heat-killed S bacteria and injected into a mouse, not only did the mouse developed disease and died, but when Griffith took a blood sample from the dead mouse, he found that it contained living S bacteria
  • Griffith concluded that the R-strain bacteria must have taken up what he called a transforming principle from the heat-killed S bacteria, which allowed them to transform into smooth-coated bacteria and become virulent

2) Experiment done by Avery:

  • Avery, McCarty and MacLeod set out to identify Griffith's transforming principle
  • They began with large cultures of heat-killed S cells and, through a long series of biochemical steps progressively purified the transforming principle by washing away, separating out, or enzymatically destroying the other cellular components
  • These results all pointed to DNA as the likely transforming principle but Avery was cautious in interpreting his results
  • He realized that it was still possible that some contaminating substance present in small amounts, not DNA, was the actual transforming principle

3) Experiment done by Hershey and Chase:

  • Hershey and Chase studied bacteriophage, or viruses that attack bacteria
  • The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA
  • Hershey and Chase concluded that DNA, not protein, was injected into host cells and made up the genetic material of the phage
