What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?
a) they strengthen each other
b) they negate each other
c) they triple the strength of each other
d) they weaken the power of each gradient by half

Option B, they negate each other

Explanation:

Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.

Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.

Option B

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
