Answer:
I believe the answer would be A
A lot of people did. Including me.
Answer:
This question is incomplete, it is asking to identify the following variables in the question:
Independent Variable: DIFFERENT AMOUNTS OF OIL
Dependent Variables: NUMBER OF KERNELS THAT POPPED
Controlled Variables: TIME FOR POPPING, SAME BRAND OF KERNEL, SAME COOKING TIME
Explanation:
The independent variable of an experiment refers to the variable that the experimenter intentionally manipulates or changes for the purpose of effecting a measurable response in another variable (dependent variable). In this experiment, the independent variable is DIFFERENT AMOUNTS OF OIL used because this is what Jason changes in the experiment.
Contrarily, the dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, Jason measures the NUMBER OF KERNELS THAT POPPED from using different amounts of oil. Hence, the NUMBER OF KERNELS THAT POPPED is the dependent variable.
Controlled variables or constants are those variables that must be kept constant or unchanged throughout the experiment in order not to influence the findings of the experiment. In this case, the following variables were kept constant for all the groups: TIME FOR POPPING , SAME BRAND OF KERNEL (Pop rite), SAME COOKING TIME (4 mins).
The statement that describes a method by which the body prevents airborne pathogens from entering the lungs during respiration is as follows: the mucus in the nose traps microscopic particles and bacteria while nose hairs filter out larger particles.
<h3>What is the role of the lungs?</h3>
The lungs are biological organs of vertebrates that controls breathing and oxygenates the blood.
The lungs is the major breathing organ of the body and is connected to the nose through a pipe called trachea and bronchi.
However, to prevent unwanted or foreign particles in the atmosphere from entering into the lungs, the mucus in the nose helps trap the microscopic particles while the hairs in the nose blocks the passage of larger particles.

#SPJ1
so ATP is adenine triphosphate
it has 3 phosphate groups, hence the 'tri'
it has nitrogen containing carbon rings
and it also had a carbon ring containing OH groups
i can't draw it on here but if you google the structure hopefully my explanation will make more sense
