New zealand has a population of 4,326,380 and has an area of 103,736 mi while australia has an area of 2,967,909 mi and a population of 21,905,140. calculate the population density for new zealand and australia. round the population densities to the nearest whole number.

25. what does meiosis create? haploids or diploid? somatic cells or gametes?

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).

Which feature would you expect to find in a population in which sexual selection depends on male competition?
