Bekah needs to take a blood sample from a patient but doesn’t have her normal tools. What could she use in place of a tourniquet on the patient’s upper arm? (1 point) Responses a knife a knife a small glass cup a small glass cup a belt a belt a paper towel a paper towel

Bekah could use a belt in place of a tourniquet on the patient’s upper arm. It can help constrict the blood flow temporarily, similar to how a tourniquet would work.

Florian’s biology teacher explained to the class that there were some organisms in the soil behind the school that could make them sick. During the class’s time to work in the garden, they had to wear gloves. What type of organisms were MOST LIKELY living in the soil? (1 point) Responses bacteria bacteria viruses viruses antigens antigens antibiotics

The organisms that were most likely living in the soil and could make them sick are bacteria. Bacteria are common in soil, and some can be harmful to humans.

Gary recently went to the doctor and had a blood sample taken. At the lab, the medical worker saw some antibodies in Gary’s blood. What does this tell the medical worker? (1 point) Responses Gary needs to consume less cholesterol. Gary needs to consume less cholesterol. Gary’s body is fighting an infection. Gary’s body is fighting an infection. Gary has a very weak immune system. Gary has a very weak immune system. Gary may have a fungal infection.

The presence of antibodies in Gary's blood tells the medical worker that Gary’s body is fighting an infection. Antibodies are typically produced in response to infections, signaling that the immune system is actively responding to pathogens.

Bryce predicts that when examining the skin of dogs without fleas, he won’t see any red bite marks. And when examining the skin of dogs with fleas, he will find red bite marks. How might Bryce BEST test his prediction? (1 point) Responses He might ask 20 dog owners if their dogs have fleas. He might ask 20 dog owners if their dogs have fleas. He might examine the skin of 10 dogs without fleas to looks for bite marks. He might examine the skin of 10 dogs without fleas to looks for bite marks. He might examine the skin of 10 dogs with fleas to look for bite marks. He might examine the skin of 10 dogs with fleas to look for bite marks. He might examine the skin of 10 dogs with fleas and 10 dogs without fleas to look for bite marks.

Bryce might best test his prediction by examining the skin of 10 dogs with fleas and 10 dogs without fleas to look for bite marks. This approach allows for a direct comparison between the two groups, helping to validate or invalidate his prediction effectively.

Aya is designing an experiment using the scientific method to answer the question, “Does eating a higher protein diet make mice stronger?” What hypothesis might Aya have? (1 point) Responses Eating a higher protein diet makes mice stronger. Eating a higher protein diet makes mice stronger. Eating a higher protein diet makes people stronger. Eating a higher protein diet makes people stronger. Eating a higher protein diet make mice smarter. Eating a higher protein diet make mice smarter. Eating a lower protein diet makes mice faster. Eating a lower protein diet makes mice faster.

Aya's hypothesis might be: Eating a higher protein diet makes mice stronger. This directly addresses her question and provides a clear statement that can be tested in her experiment.

Portia is creating a scientific experiment for her biology class. She is using the scientific method to plan out the steps of the experiment. What is Portia MOST LIKELY trying to accomplish through her experiment? (1 point) Responses to discover an answer to her question that is supported by evidence to discover an answer to her question that is supported by evidence to discover an answer to her question that is NOT supported by evidence to discover an answer to her question that is NOT supported by evidence to prove that her idea is correct even though the evidence doesn’t support her to prove that her idea is correct even though the evidence doesn’t support her to make an entirely new observation about what she is studying

Portia is most likely trying to discover an answer to her question that is supported by evidence. The scientific method is designed to test hypotheses and gather data to support or refute claims based on evidence.
