How a postsynaptic neuron’s decision to fire depends on the ratio of EPSPs and IPSPs Introduction: The neural integration depends on the postsynaptic potentials that are generated by neurotransmitters. The threshold of typical neuron is -55 mV and the resting membrane potential (RMP) is -70 mV. In order to produce an action potential, a neuron must be depolarized to this threshold. Any change in the voltage, in that direction induces a neuron to fire, hence it is called as an excitatory postsynaptic potential. EPSPs results from the inflow of Na + into the cell that neutralizes the negative charge (some) inside the membrane.

Question

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction.
