Chapter 35.5, Problem 1CS
Core Skill: Modeling The goal of this modeling challenge is to draw a reptilian phylogenetic tree that distinguishes the four recognized taxa based on critical innovations that are morphological traits.
Modeling Challenge: Turtles, lizards and snakes, crocodiles, and birds are all considered reptilians, yet we recognize them as distinct taxa. Construct a model of a phylogenetic tree using six critical innovations: three- or four-chambered heart, scales, endothermy, a hard protective shell, a kinetic skull, and feathers. Be sure to show these critical innovations on your phylogenetic tree with black bars and labels. The four taxa have the following combinations of traits: Crocodilia (four-chambered heart, scales, not endothermic, no protective shell, no kinetic skull, no feathers); Squamata (three-chambered heart, scales, not endothermic, no protective shell, kinetic skull, no feathers); Testudines (three-chambered heart, scales, not endothermic, hard protective shell, no kinetic skull, no feathers); Aves (four-chambered heart, scales, endothermic, no protective shell, no kinetic skull, feathers).

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? (4
pts)?

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.

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward9.
