A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35

percent. However, when five independent laboratories conducted the same experiment, they measured a reduction rate of only 5–8 percent.
How did these laboratories show that the pharmaceutical company’s claims were invalid?

The labs used the pharmaceutical company’s inadequate data.
The labs produced false data.
The labs recorded data incorrectly.
The labs were unable to reproduce the pharmaceutical company’s data.

<span>The labs were unable to reproduce the pharmaceutical company’s data

An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.

Explain what is meant by the term transverse section
KatRina [158]

Answer:

A transverse section is a cross-sectional part that is achieved by cutting the body or any part of the body structure in real or with help of imaging techniques in a horizontal plane. That plane crisscrosses the longitudinal axis at a 90-degree angle.

Explanation:

A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane that intersects the longitudinal axis at a right angle. Because actual sectioning in the transverse plane results in inferior and superior portions, an anatomic transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections usually demonstrate the form

A frog is able to leap away from a snake because danger is sensed and responded to by OA. the immune system O B. the nervous sys
Anna11 [10]

Answer:

B. the nervous system

Explanation:

The nervous system is one of the body systems that has to do with the passing signal information to and fro the BRAIN and other sensory organs e.g eyes, nose, ears etc. The nervous system is what causes an individual organism to sense and respond to environmental stimuli by passing chemical signals to the brain and back to the site of effect.

According to this question, a frog is able to leap away from a snake because danger is sensed and responded to by the NERVOUS SYSTEM. Information in form of chemical signals (impulses) are passed across the brain of the animal of a possible threat, which then sends back information for the frog to react to such danger by leaping away.
