What is an organism that shows positive and negative gravitropism?
Gravitropism (or geotropism) is a turning or growth movement by a plant or fungus in response to gravity. Charles Darwin was one of the first Europeans to document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behaviour can be easily demonstrated with a potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, bending (biologists say, turning; see tropism) upwards. Herbaceous (non-woody) stems are capable of a small degree of actual bending, but most of the redirected movement occurs as a consequence of root or stem growth in a new direction.B_TCH SH_T MOTHER F_UCKER

Why is negative four to the fourth power negative?
Because A Negative x A pOsItIVE = nEgaTiVE * * * * * (-4)4 = 256. It is positive, not negative. The most likely reason for getting a negative result is that no brackets were used and so what was calculated was actually -44
Is Gold A Positive or negative ion?
Gold can form both positive and negative ions, depending on the conditions. In its most common form, gold typically forms positive ions by losing electrons.
What is the most likely blood type of the father if the mother is O positive and two children are A negative?
The father's blood type could be either A positive or A negative. The children inherited the A antigen from the father, resulting in their blood type as A negative. The Rh factor (positive or negative) is inherited separately, so the father could be either positive or negative.
