A paleontologist believes he has discovered a new species of dinosaur. Describe how he can use vertebrate homologies to confirm his belief.
Homework Answers
Paleontalogy is the study of evolution using fossil records
Using fossil evidence such as organisms or plant materials or prints on caves , the evolutions of organisms can be studied.
By using homological structures in fossils or samples of vertebrate species, we can confirm whether the new species is dinosaur or not.

If you were a scientist who believes he has discovered an inexpensive new energy source that doesn’t pollute, and you designed an experiment to assess whether or not this energy source actually worked, would you rather protect yourself from making a Type I or Type II error? Why？

A geneticist discovered a new species of insect with variable antennae length. He performed the following cross (Bb x bb) and counted the number of offspring with different antennae lengths. He was unsure if his observations matched what he expected to see, so he performed a chi-squared goodness of fit test and calculated ?2 = 0.051. If only two phenotypes were possible, can he reject the null hypothesis? No. P > 0.05 so any difference seen was not due to...

A geneticist discovered a new species of insect with variable antennae length. He performed the following cross (Bb x bb) and counted the number of offspring with different antennae lengths. He was unsure if his observations matched what he expected to see, so he performed a chi-squared goodness of fit test and calculated Х 2 = 4.03. If only two phenotypes were possible, can he reject the null hypothesis? No. P < 0.05 so any difference seen was due to...

QUESTION 6 A new species of sea crab has been discovered, and an experiment conducted to determine whether or not the animal can regulate its temperature. If the animal can maintain a body temperature different from the surroundings, this would be considered evidence of regulating capability. Ten of these sea crabs were exposed to ambient temperature of 24 degrees Celsius. Their body temperatures were measured with the results below: 24.33 24. 61 24.67 24.64 24.42 24.97 25.23 24.73 24.90 24.44...

()2. I discovered a new mushroom species, Agaricus flurkeatus, and identified some of the lipids in the stalk. I found ergosterol and an ergosterol ester (in small amounts) containing arachidonic acid. I also found small amounts of mixed triglycerides containing predominantly linoleic and palmitic fatty acids. There was also a small amount of "free" myristic fatty acid. Phosphatidyl serine was much more abundant than phosphatidylcholine in the cap. A triacyighycerol lipase was present that hydrolyzed some of the triglycerides extracted...

his recommendation last week. It was then that he discovered that a system had already been purchased. The clinic’s other owner had assigned the computer research task to another employee. Upset that his time and ideas were wasted, Hank has let everyone know just how disorganized and unfair his employers are. His coworkers are tired of hearing about it and wish Hank would just forget it. Do you believe that Hank’s reaction to the situation is appropriate? Why or why...
