Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.
Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.

(B) Contributions to the field of biomedical research are generally considered to be significant only if the work is published.
(C) The potential scientific importance of not-yet-published work is sometimes taken into account in decisions regarding the hiring or promotion of biomedical researchers.
(D) People responsible for hiring or promoting biomedical researchers can reasonably be expected to make a fair assessment of the overall impact of a candidate's publications on his or her field.
(E) Biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one.
Answer: E
Explanation:
The statement if correct argues most strongly against the claim that biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one in the sense that what counts is not the numbers of publications but it's impact. Meaning that a researcher can have several publications but yet with low impact in the field.
B. notochord
C. pharyngeal slits
D. dorsal fin.
2. Ancient chordates are thought to be most closely related to which of the following species?
A. spiders
B. earthworms
C. octopi
D. sea stars
The notochord is a flexible, supporting structure found only in chordates. Ancient chordates are most closely related to octopi.
The correct answer for the first question is B. notochord. The notochord is a flexible, supporting structure found only in chordates.
It provides support to the body and serves as a precursor to the vertebral column in vertebrates. Examples of chordates include fish, birds, and mammals.
The correct answer for the second question is C. octopi. Ancient chordates are thought to be most closely related to cephalopods like octopi.
Both groups share certain characteristics in their body structure and development.
