A personal trainer thinks her clients get better workouts and are stronger if they listen to music while working out. Over the next week, she divides her 20 clients into two groups of 10. For the first group, she plays music and sees if they can lift a barbell weighing 50 lbs. For the second group, she repeats the test but does not play any music. All 10 members of the music group could lift the barbell, but only 7 members of the no music group could lift the barbell. She concludes that her hypothesis was correct and decides to always play music for her clients.
Which group was the control group?
Answers
Answer:
The correct answer is: the group of 10 people that lifted the barbell with music is the control group.
Explanation:
The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.
The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.
The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.

Answers
Answer:
II. the textures of organs
Explanation:
A human torso model is designed to be as accurate as possible so that students/researchers can understand the inner workings of the body. Therefore, the organs have been designed to be the same size of an actual human being of that stature, while also being in the correct position within the body to better understand the interrelationships between the organs. The only thing that is not accurate in these models is the texture of the organs as most are smooth plastic unlike the actual organs.

What must happen before a chemical reaction can begin
- the activation energy must be exceeded
- the activation energy must be reached
-the concentrations of products and reactants must be equal
- the concentration of reactant molecules must be reduced
Answers
Answer:
its B
Explanation:
The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.
What is activation energy?
The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product.
Factor at which activation energy depends are as follows:-
1: Activation energy depends upon the nature of reactant if reactant is ionic then required activation energy is less and if reactant is covalent then required activation energy is high.
2: Nature of catalyst if catalyst is positive then required activation energy is less and if catalysts is negative then required energy is high.
3: Activation energy doesn't depend on pressure, temperature, volume etc.
Temperature is one the important factor at which any reaction is depend. In any reaction if temperature is increases the rate of reaction is increases and if temperature is decreases the rate of reaction is decreases.
Here, is the Arrhenius Equation which shows the temperature dependence of the rate of a chemical reaction.
k=Ae^−EaRT
Where,
k= rate constant of the reaction
A= Arrhenius Constant
Ea= Activation Energy for the reaction (in Joules mol^-1)
R= Universal Gas Constant
T= Temperature in absolute scale (in kelvins)
Therefore, The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

Why does a pollutant end up multiplied as it travels up the food chain from producers to consumers?
Answers
Answer:
This is due to bio magnification.
Explanation:
When there is a gradual increase in concentration toxins(pesticides) in the tissues of organisms progressively in the food chain,the term for describing this is called -bio magnification.
The progressive multiplication in the concentration of these toxins may be due to non-biodegradable nature of the toxins,which are absorbed into the tissues of mostly the producers from the environment faster than they could metabolized by the body.
.Therefore these could not be removed by the producers, during excretion and respiration,and hence build up progressively upwards in the consumers.
A typical example is the phytoplankton which absorb toxins from sea water and accumulate this in the body.The build could not be ,metabolize by the body system,and is transferred to the zooplankton along the food chains when they feed on the phytoplanktons- this is Bio magnification.Which of the following is the best definition of a system?

Answer:
B. a group of connected or related things?
Explanation:
A system must have some form of relationship between the components inside of it. All these components work together to do a certain task or to run efficiently.
For example, let's take the court justice system. Inside the system is broken down into a range that can go from small claims court to the Supreme Court of the United States. This system is to ensure that their is not only a smaller burden on the supreme court to be able to take care more of national & international claims, but also so that if a citizen feel that they have a unfair ruling, they may bring it up to a different court that may not have local preferential to a certain degree.
All parts of a system is connected or related to each other, either as a cause, and effect, or a solution.
