While testing the effectiveness of a new antibiotic, researchers use three groups with
the following treatments:
• Group 1--receives a placebo
• Group 2: receives antibiotic A
• Group 3: receives antibiotic B
Which of the groups would not be considered a control group?
o the group that received antibiotic A
o the group that received the placebo
o the group that received antibiotic B
O both groups receiving antibiotic A and B
Researchers use three groups when testing the efficacy of a new antibiotic, so both groups receiving antibiotic A and B, are not a control group, but the ones that received the placebo is a control, so the answer is in the last option.
What is the significance of the control group?The control group has various significant characteristics that allow researchers to compare the effectiveness of the experimental data with the standard and check the effectiveness, but the control group does not receive the experimental treatment. Here, the placebo-treated population is the control group, while the other two groups are experimental and can be taken as the control group.
Hence, researchers use three groups when testing the efficacy of a new antibiotic, so both groups receiving antibiotic A and B, are not a control group, but the ones that received the placebo is a control, so the answer is in the last option.

How is the solubility of most genes and solids in water affected by the temperature of the water?
Answer:
in higher temperatures the molecules will increase however in colder temperatures the molecules will decreasing and eventually melt. (more info below)
Explanation:
if the water is hot, the average kinetic energy of its molecules will increase. As a consequence, the solution is capable of extracting additional ions from the surface of the solute. As a result, temperature increases the solubility of substances. Sugar and salt, for example, are more soluble in water at higher temperatures.When the temperature of the solution changes, the total kinetic energy of the molecules that make up the solution often decreases.The enhanced friction (kinetic energy) of the molecules of the solute allows them to be less able to stay on and therefore melt more quickly.
hope this helped!

A plant disease infected a field of wild blackberries. The first year many of the plants died from the disease. The next year fewer plants died. The third year, almost none of the plants died of the disease.
Why did fewer plant die from the disease each year?
A. Over time, the species became less resistant to the disease.
B. All of the plants in the species were resistant to the disease.
C. None of the plants in the species were resistant to the disease.
D. Plants that were resistant to the disease lived and reproduced.
Answer: I think it’s D
Explanation: it makes the most sense
The plant species that were resistant to the disease lived and reproduced. So, the correct option is (D).
What is Plant pathology?Plant pathology is defined as the scientific study of diseases in plants which is caused by pathogens and environmental conditions. Organisms which cause infectious diseases such as fungi, oomycetes, bacteria, viruses, viroids, phytoplasmas, etc.
It includes pathogen identification, disease cycle, disease etiology, economic impact, plant disease epidemiology, study of plant disease resistance. Studies also include how plant diseases affect humans and animals, genetics and the management of plant diseases.
Over time, plants become more resistant to the diseases that caused them to live and reproduce.
Thus, the plant species that were resistant to the disease lived and reproduced. So, the correct option is (D).
