A manager wanted to test whether the amount of noise in a clothing factory affected how
much work employees accomplished. Three groups of employees were tested every day
over a 5-day period. All three groups did the same type of work, they were all equally trained
to do the work, they used the same equipment, and they were tested the same time of day.
Group one was given headphones that blocked out all of the outside noise. Group two was
given headphones that blocked out some of the noise. Group three was not given anything
to block out the noise. The number of shirts made by the employees in one hour was
determined.
What is the dependent/responding variable?
The amount of noise.
O The number of shirts made by the employee.
O The type of music the employees listen to while they work.
O The amount of training employees need.
Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.
Explanation:
In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.
It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.
For the other options:
The amount of noise. This can modified by the use or not of headphones and is the independent variable, subject to modification.The type of music the employees listen to while they work. Does not represent dependent or independent variable.The amount of training employees need. It is not the variable being studied.Question 6 (1 point)

Answer:
(D)
Explanation:
Just took the test on edge
In this three equations below, Nuclear fusion plays an important role in making elements that are heavier than helium. Hence option D is correct.
What is nuclear reaction ?There are two types of nuclear reactions. Nuclear fission and nuclear fusion.
Nuclear reactions are classified into two types: fission and fusion. Nuclear fusion is the collision of two or more light nuclei to produce a heavier nucleus. Nuclear fusion happens in low-atomic-number elements such as hydrogen. Nuclear fusion is the inverse of nuclear fission, in which heavy atoms scatter and lighter elements are produced. Nuclear fusion and fission both provide massive quantities of energy.
A nuclear process in which low-atomic-number atomic nuclei fuse to form a heavier nucleus, releasing energy.
Every star in the universe, including the sun, is alive because of nuclear fusion. As a result of this activity, they create enormous amounts of heat.
Fission is a nuclear phenomenon in which a heavy nucleus spontaneously fractures or collides with another particle, releasing energy. Nuclear fission happens when an atom's nucleus splits into lighter nuclei as a result of a nuclear process. This decay can occur naturally due to radioactive decay, or it can be mimicked in a laboratory by creating the necessary conditions (bombarding with neutrinos). The overall mass of the resulting fragments is less than that of the original. The missing mass is converted into nuclear energy in the preceding step.
hence option D is correct.

What is a food chain?A food chain is a linear sequence of organisms in which each organism serves as a food source for the next organism in the chain. The organisms in a food chain are connected by their feeding relationships, with energy and nutrients passing from one organism to the next.
Producers are organisms that form the base of the food chain by converting sunlight into chemical energy through photosynthesis. These organisms are typically plants, algae, or certain types of bacteria. They are called producers because they produce their own food, using energy from the sun and inorganic nutrients from their surroundings. As a result, they are able to support all other levels of the food chain, including herbivores, carnivores, and omnivores.
