ANSWER ASAP Which of the following statements about the rate of Co, fixation in the two types of plants is supported by the data shown in the figures?
A) A 21% 0s, plant type 2 has a lower rate of CO, fixation than plant type 1 does in both types of soil
B) 411% 0, plant type 2 has a higher rate of Co, fixation than plant type 1 does in the dry soll but not in the control soil,
Plant types 1 and 2 have a statistically different rate of CO, fixation in both soil types at both oxygen levels,
D
The rate of CO, fixation is the same in both types of plants in the control soil at both oxygen levels.

Nasa scientists must work together to make sure that everything is correct and accounted for when launching a shuttle. besides a physicist, what other type of scientist would be in making sure that the shuttle has the appropriate type and amount of fuel to reach its destination?

Pl which diagram illustrates prophase?

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
