Answer:
(E) Soil disturbances can result in fewer blooms, and hence lower seed production.
Explanation:
According to the experiment, the eight control plots were left undisturbed, that is, their soil was not exposed to any disturbance. On the other hand, the soil of the experimental plots was disturbed during the removal of dandelion species. This disturbance might have resulted in reduced flowering in the experimental plots due to many reasons such as removal of fertile topsoil.
The reduced flowering in these plots might have caused lower seed set. The control groups had undisturbed soil which in turn favored more flowering and seed production than in the experimental groups.
Answer:
The independent variable is the variable: it is listening to music through his headphones.
The dependent variable: it is increase in exposure to excessive noise
Explanation:
the two variables in this context are
- listening to music through his headphones.
- increases his exposure to excessive noise.
The independent variable is the variable whose variation does not depend on that of another and in this case, it is listening to music through his headphones.
The dependent variable is what is being studied and measured in the experiment and in this case, it is increase in exposure to excessive noise
Some electromagnetic waves have a long wavelength (radio and microwaves) but other have a smaller wavelength (xrays and gamma rays) and therefore it can penetrate your skin and cells and destroy/mutate then which can cause cancer.
