Activity
Choose one biodiversity hotspot (for example, the Cape Floristic Region). Brlefly describe the geography of the region. How many plant species
are found there? Of those, how many are endemic? Describe some of the conservation measures for protecting the ecosystem in the region.

Did you know that a blue wales tongue weighs more than an elephant?

Why is it incorrect to say that mitochondria function only as energy factories with cell

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).
