The autonomic regulation of cardiac function and effects of autonomic activity on the rate and force of ventricular contraction and starling curves in order to support the explanation. Introduction: The cardiac output is the amount of blood pumped by the heart per minute. The cardiac output is the product of the heart rate and the stroke volume. Heart rate is the number of beats per minute and stroke volume is the amount of blood for each beat. The two primary modes by which the blood volume pumped by the heart is regulated by two factors, i.e., intrinsic cardiac regulation in response to changes in the blood volume flowing into the heart; and control of the heart rate as well as cardiac contractility by the autonomic nervous system.

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.
