Summary Introduction

To determine: Whether the pulmonary surfactant will increase, decrease, or not change lung compliance.

Introduction: Alveoli are clumped at the ends of terminal bronchioles present in the lung. Alveoli are air-filled and allow gas exchange between themselves and the blood. Type II alveolar cells are small but thick and secret a chemical known as pulmonary surfactant. The pulmonary surfactant is the mixture of proteins and lipds.

Summary Introduction

To determine: Whether the pulmonary surfactant will increase, decrease, or not change the surface tension of alveoli of lungs.

Introduction: The pulmonary surfactant is the mixture of proteins and lipds and therefore it has both hydrophobic and hydrophilic nature. The pulmonary surfactant is secreted by the type II alveolar cells in the alveolar space. Type II avleolar cells are hollow and present at the ends of terminal bronchioles.

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.
