Local hormones are a huge group of signaling molecules. These are released from the cells which produce them or are secreted from neighboring cells. Eicosanoid is a primary type of local hormone which is released from fatty acids. It is formed by an enzymatic cascade. It causes the stimulation of cells that produced it (autocrine stimulation) or its neighboring cells (paracrine stimulation). Leukotrienes from damaged tissue cause smooth muscle in local blood vessels to vasodilate or increase the vessel lumen.

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.
