While researching a topic, a student has taken the following notes: Jonas Salk developed the first effective polio vaccine in 1955. The vaccine was made from dead poliovirus. Salk originally hypothesized that only a vaccine with live virus could be effective. His vaccine drastically reduced the global incidence of polio. The reduction of polio has greatly improved global public health.24Mark for ReviewABCThe student wants to emphasize the significance of Salk’s discovery. Which choice most effectively uses relevant information from the notes to accomplish this goal?AJonas Salk developed the first effective polio vaccine in 1955.BSalk’s 1955 development of the first effective polio vaccine drastically reduced the global incidence of polio, leading to great improvements in global public health.CThe vaccine developed by Jonas Salk in 1955 was made from dead poliovirus.DAlthough his vaccine was made from dead virus, Salk originally hypothesized that only a vaccine with live virus could be effective.

While researching a topic, a student has taken the following notes: James Watson and Francis Crick proposed the double helix structure of DNA in 1953. This structure allowed for DNA to be easily copied during cell division. Watson and Crick initially thought DNA copied itself through a conservative mechanism. Their discovery revolutionized the understanding of genetics. An improved understanding of genetics has led to breakthroughs in medical treatments.27Mark for ReviewABCThe student wants to emphasize the significance of Watson and Crick's discovery. Which choice most effectively uses relevant information from the notes to accomplish this goal?AWatson and Crick's proposal of the double helix structure of DNA in 1953 revolutionized the understanding of genetics, leading to breakthroughs in medical treatments.BIn 1953, Watson and Crick proposed the double helix structure of DNA, which they initially believed copied itself through a conservative mechanism.CThe double helix structure of DNA facilitates copying of DNA during cell division.DEven though Watson and Crick's double helix model revolutionized the understanding of genetics, they incorrectly believed at first that DNA copied itself through a conservative mechanism.

8)While researching a topic, a student has taken the following notes:● Poliomyelitis (or polio, for short) terrorized America and Europe until the 1960s.● It paralyzed more than 15,000 people a year in America and 8,000 in Britain, mostlychildren.● There is no treatment for polio and 5-10% of paralytic cases are fatal.● The invention of a vaccine set the world on a path to eradication.● The Americas region was declared free of the wild poliovirus in 1994.● Europe followed in 2002 and Africa in 2020. The student wants to emphasize on theseverity of polio disease. Which choice most effectively uses relevant information fromthe notes to accomplish this goal?RSYPRAEN-008Until the invention of polio vaccine and subsequent eradication programs, the western world had been in the grip of polio terror.In the absence of any suitable treatment for poliomyletis, America had been the worst polio affected country until the 1960s.Since there was no treatment for poliomyletis until the invention of vaccine, when once somebody used to get afflicted with polio treatment was only available after the invention of the vaccine.The fatality rate among paralytic cases due to polio was around 5-10% and the number of the polio-affected, mostly children, was 15,000 in America and 8,000 in Britain annually

While researching a topic, a student has taken the following notes:Recent studies have shown a decline in honeybee populations globally.Dr. Anita Singh and her team at the Oregon State University are investigating this decline.Their research includes monitoring bee colonies and analyzing environmental factors.The study aims to identify the main causes of honeybee population decline.Initial findings suggest that pesticides and habitat loss are significant factors.The student wants to emphasize the primary goal of Dr. Singh's research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?Choose Your AnswerPreviousNextA.Dr. Anita Singh and her team at Oregon State University are monitoring bee colonies to understand the global decline in honeybee populations.B.The research led by Dr. Anita Singh at Oregon State University aims to identify the main causes of the decline in honeybee populations.C.Oregon State University's study, under Dr. Anita Singh, has found that pesticides and habitat loss significantly impact honeybee populations.D.Dr. Singh's team is analyzing environmental factors affecting honeybees, focusing on the reasons behind their global population decline.
