Question:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the________ group. The plants with just potting soil are the________ group.
Answer:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the__experimental__ group. The plants with just potting soil are the__control_ group.
Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one that receives the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
In the exposed example, the coffee in the soil is acting as the treatment. And the regular soil is the unchanged environment.
Plants that grow in soil with coffee are the experimental group because the researcher wants to know how the coffee affects the plants´ growth.
Plants growing the regular soil are the control group because they are not affected by the coffee. If there is any other factor influencing the results in the regular soil, it will be revealed by these plants.
In an experiment, data from the experimental group is compared with the data from the control group.
The given blanks for the statement can be given as:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the experimental group. The plants with just potting soil are the control group.
The experiment involves an experiment and a control group. The value from the experimental group is measured with the values obtained from the control group.
The data in both groups are selected from a similar gene pool or population.
The control group in an experiment helps in the identification of the factors influencing the probable results.
The experimental group is the one that undergoes the experimental procedure or treatment. The independent variables are voluntarily changed and the researcher observed the effects of variables in the experimental group.
The variables in the control group are constant and do not affect the results, whereas in the experimental group the variables are changed and affect the results.
For example, the coffee in the soil is a type of treatment, in which the regular soil is the unchanged environment.
Plants will grow in the environment where the coffee has been incorporated, and the researcher wants to study the impact of coffee on the growth of the plant.
Plants in the regular soil will not be affected by the coffee and are the control group. The factor influencing the results in regular soil will be expressed in the plant.

: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!
Answer:
This would be an example of technology.
Explanation:
Artificial limbs, or prostheses, are used to replace a missing body part which may have been lost due to trauma, disease or congenital defect. The type of prosthesis a person can use is dependent on the individual, including the cause of amputation or limb loss, and the location of the missing extremity. These come in all shapes and sizes, for whatever you need.
Have a nice day!
Answer:
A technology, since the actual prosthesis is a human creation that solves a problem. Science is nothing physical. It is the combination of laws and theories that explain our universe and helps us make decisions. We don't really invent science, we describe it.
Science is ideas. Technology is human creations.
Science generally underpins all new technology.
In your human leg prosthesis example science is crucial in choosing (or developing) suitable materials for construction of the prosthesis. The material must be relatively stable, not break down into toxic substances and have good durability. Knowledge of human Biology is also important if you want to start replacing human body parts.
Basically chemistry and biology are important in the prosthesis development. There is also probably physics regarding tensile strength requirements.
The actual end result of the human prosthesis is a technology which solves a problem of degraded human parts.
So to reiterate, it is a technology.

11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
Answer:
The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.
These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.
These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.
People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.

Answer:
Hi, there your answer is C. The person is having a heart attack.
Explanation:
This picture is an electrocardiograph (ECG). The ECG is a graph which shows cardiac activity. It is a reading of the electrical impulses in the heart that activates heart muscles and pumping action of blood. An ECG is obtained by fixing 12 electrodes on different body locations like chest, arms, legs which detects the electrical impulses of the heart muscle. The output generated on an ECG consists of peaks. The elevation of peaks in ECG indicates abnormal heart activity or heart attack.
This picture is showing continuous elevated peaks therefore, indicates that the person is having a heart attack.

Answer:
The correct answer is - Commensalism
Explanation:
Commensalism is a symbiont relationship in which there is a relationship between two organisms in which one gets benefits and the other organism is unaffected.
Human skin has many commensal bacteria that fed on dead cells of the skin. Here humans are hosts that do not get harm and bacteria rely on them for survival.

Which is a layer of sedimentary rock that forms from calcium carbonate in the deep ocean?
Salt
Limestone
Sandstone
Shale
Answer:
Limestone
Explanation:
Limestone is made up of carbonate minerals, such as calcite. The shells and skeletons of ocean organisms are formed of these minerals. When the organisms die, the shells and skeletons settle on the ocean floor as layers of sediment. Over time, the layers become buried, pressed together, and cemented to form limestone.
