Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment?

How do I set up and collect data in a data table and identify trends?
Answer:
Explanation:
To collect information you need to read and understand why it works and make an analysis of what you understood about the information in the table
and this is how you find the trends. A trends can often be found by establishing a line chart. A trendline is the line formed between a high and a low. If that line is going up, the trend is up. If the trendline is sloping downward, the trend is down.
Which best defines homeostasis? modifying the external environment maintaining a stable internal environment controlling what enters and exits the cell movement of materials into the cell
Answer:
B. maintaining a stable internal environment
Explanation:
Took the test :)
Answer: yes its B
Explanation:
Water, a stable liquid, is formed when two flammable gases, hydrogen and oxygen, combine. What has happened?
O An atom has been created.
O A compound has been created,
O A mixture has been created,
An element has been created
Answer:
A compound has been created
Explanation:
Remember you cannot create an atom nor can you create an element so An atom has been created and An element has been created is incorrect. Also, a compound is something that is chemically bound and cannot be separated unless applied a chemical change, which is applicable to water. It cannot be a mixture since mixtures can be separated physically, which you can't do with water.

___are a major component of the membrane of
all cells.
Answer:
Proteins and lipids are the major components of the cell membrane.
Explanation:
Depending on the membrane’s location and role in the body, lipids can make up anywhere from 20 to 80 percent of the membrane, with the remainder being proteins. While lipids help to give membranes their flexibility, proteins monitor and maintain the cell's chemical climate and assist in the transfer of molecules across the membrane.

Give an example of warning coloration used in
nature.
Answer:
Warning coloration (aposematism) is effectively the "opposite" of camouflage and a special case of advertising. Its function is to make the animal, for example, a wasp or a coral snake, highly conspicuous to potential predators, so that it is noticed, remembered, and then avoided.

Which would most likely interact with an open flame and cause an accident
A-Covered shoes
B-Contact lenses
C-Goggles
D-Loose hair?
Answer:
D, loose hair.
Explanation:
If your hair is long enough, it could easily drift into the flame and catch on fire.
Answer:
D. Loose hair
Explanation:
Loose hair would be the most likely to cause an accident with an open flame.
Especially if the hair is long, it can dip down into the flame and catch on fire.
The other objects would not be interacting with the flame because they would be far away, while loose hair can reach into the area where the flame is.

Students in a biology class were discussing outbreaks of food-borne illness. Modern practices of refrigeration are aimed at curbing (limiting) these bacteria. They wanted to know exactly what happened to bacterial colony growth at varying temperatures. The teacher explained that scientists study bacteria in the laboratory by counting colonies that grow on plates filled with agar, which is a nutrient substance. “Design” an appropriate experiment that would test the effect of temperature on bacterial growth. You would have a period of 5 days to conduct an experiment.
Answer:
I know this isn't a big help answer, but you could use it as a start. You could say something like "I tested it in multiple different temps. including .... (any temps. you want) Then say how all of thoose different temps. changed the bacteria." I hope it helped! :)
Explanation:
Most of the foodborne diseases are caused by those bacteria that can grow well and infect food at normal temperatures, and their population can be controlled by lowering the temperature or raising the temperature too high, which can degrade their cell walls.
What is the effect of temperature on the bacteria?There are numerous bacteria that can infect food and cause foodborne disease when consumed by humans, resulting in diarrhea, stomach aches, and other symptoms. Because most of these bacteria grow at room temperature, keeping food at that temperature degrades it faster, so foods are kept and stored in the refrigerator. This low temperature keeps the cellular activity of bacteria low; as a result, the bacteria cannot produce toxins or grow their population.
Due to this, the refrigerator stores the food for a longer time. Different strains can be kept and stored at different temperatures on an agar plate, but a strain present at a low temperature will produce far fewer colonies than one present at a room temperature. Further the growth depends upon the types of bacteria.
Hence, by refrigerating the food, cellular activity is seized and controlled.
