The human heart is a four-chambered muscular organ that is associated with the circulation of blood throughout the human body. It is a part of the circulatory system that consists of blood vessels (arteries, capillaries, and veins) along with the heart. The heart is located within the ribcage between the lungs, slightly left in position. The upper two chambers are referred as auricles or atrium, while the lower two chambers are referred as ventricles. Antrio-ventricular valves are present in between atrium and ventricles that separates them from one another. These valves include mitral valve and tricuspid valve. Tricuspid valve is present on the right side, while mitral valve is present on the left side.

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.
