1. During DNA replication, an open section of DNA, in which a DNA polymerase can replicate DNA, is called a .2. The enzyme that can replicate DNA is called .3. The new DNA strand that grows continuously in the 5' to 3' direction is called the .4. are the short sections of DNA that are synthesized on the lagging strand of the replicating DNA.5. After replication is complete, the new DNAs, called , are identical to each other.

Name one similarity and one difference between the morphology of a brachiopod and a bivalve

Which set of characteristics best describes sedimentary rock? a) largest type of rock, made of organic matter, hardest type of rock b) often contains layers, forms near sources of water, contains fossils c) least abundant type of rock, made of other rocks, made mostly of minerals d) most abundant type in earth's crust, made of magma/lava, contains no fossils

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).
