Answer:

D. The type of music each plant listens to

Explanation:

The question indicates each plant is in the same soil (so cannot be C), received the same amount of sunlight (so cannot be B) and the same amount of water (cannot be A).

However, each plant is exposed to a different type of music, one is listening classical,  another rock  and another country music.

So, the only variable in here is the type of music each plant listens to.

Pani-rosa [81]
The correct answer is the color yellow.
An afterimage is best described as a photograph that continues to seem in a single's imaginative and prescient after the publicity to the original picture has ceased. An afterimage may be a ordinary phenomenon or may be pathological. Illusory palinopsia can be a pathological exaggeration of physiological afterimages. Afterimages arise due to the fact photochemical activity in the retina keeps even whilst you are no longer experiencing the unique stimulus.

A reduction in the natural hormone estrogen levels could be a causative factor in heart disease increase within post-menopausal women. Estrogen is thought to show a positive impact on the inner layer of artery wall, functioning in such a way to keep blood vessels elastic.

In spite of the advantages of estrogen, the American Heart Association speaks against employing postmenopausal hormone therapy to decrease the likelihood of coronary heart disease or stroke as some research works have revealed that it vividly do not decrase the risk of heart attack but increases the likelihood of blood clots and stroke.
