The claim that a certain species of plants produce ammonia in their roots to counteract the negative effects of acidic soil would be supported by which of the following observations?T
he frequency in the population of individual plants that produce high levels of ammonia in their roots increases with soil acidity.
As the acidity of the soil increases, the number of individual plants able to survive and reproduce decreases.
When the plants are grown in soil with a neutral pH, the levels of ammonia in the roots of the plants remains stable over generations.
When plants that produce high levels of ammonia are crossed with plants that produce low levels, the offspring survive.

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later. when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )
