Diablo Valley College Biomechanics and Primate Locomotion Lab Report
Here goes round two of Lab Reports. This one is going to pull from two separate Virtual Labs, though you will see that they relate to the same concept. Each of the labs provides such little content that the two should really be grouped together in creating a cohesive whole.
Begin this assignment by reading the Lab Exercises for both Lab 3 and Lab 4. These are the datasets you will be working with. Sections 2 and 3 of Lab 4 will provide you with general anatomical information regarding the bones you are working with.
The goal of the lab report is to make inferences about locomotor behavior by analyzing skeletal material. This is what we do in paleontology. Since we seldom (if ever) find a complete skeleton, we have come up with a variety of ways to discuss life history, adaptations, and behavior from most elements of the skeleton. This aspect of paleontological work encompasses the fields of biomechanics and functional morphology. These elements do not always tell us the whole story, but every little bit counts.
Before you dive into your work I want to clarify what data you are to use. The activity in Lab 3 is pretty straight forward. Other than some color-coding issues in the scatter plots, you should not run into many problems. It doesn’t quite show you the parameters for measuring the Olecranon Process vs the Ulnar Shaft. Do your best by examining the image on the opening page. Even if you struggle, however, the lab ultimately gives you the measurements to work with.
Lab 4 is unfortunately a little more convoluted. After you get through the review of Scientific Method, the lab shows you how to measure the Humerofemoral Index. This is your primary metric for this activity. After you go through the motions of obtaining this index, however, Kappelman gives you a different metric (the Intermembral Index) as well as body mass. Ignore these! Proceed in this report only by using the indices that you measured (Olecranon-Ulnar & Humerofemoral). The lab explains that this measurement can be used as an approximate for the Intermembral Index and so that is how we will use it. It is important to treat this exercise as if you only have three bones to study (Humerus, Ulna, Femur). When reporting on the intermembral index, state clearly that you are using the Humerofemoral Index as a proxy. This will not ruin your interpretation as it plots in the same general area. Honestly, I don’t know why he throws extra data at you. It’s unnecessary and less realistic.
I also want you to ignore the body mass provided for you (also unrealistic). You are asked to make assumptions about body mass in your conclusions. In plotting the Humerofemoral index on the Intermembral Index plot, you will see a range of body sizes that are common for this Index. That is what you discuss.
Finally, ignore the behavioral data. If you could study these primates in real time their identity would not be a mystery…
Lab Report 2: Biomechanics and Primate Locomotion
Between Labs three and four, Kappelman provides students with two metric activities. These focus on a specimen titled “mystery primate”. Students are provided with three osteological elements to assess: the Ulna, the Humerus, and the Femur. With these in hand, two separate biomechanical indices are obtainable. The Olecranon-Ulnar index measures the length of the Olecranon Process relative to the length of the Ulnar Shaft. The Humerofemoral index measures the relative proportion of the forelimb to hindlimb. Each of these indices can be used to make assumptions about the mystery primate’s locomotor style.
This lab report will be an exercise in paleontology. Students are said to have found these three elements and are asked to provide insight into the locomotor style. Your report should follow the following outline/answer the follow question.
Introduction (In any order, include the following)
-Explain what is meant by locomotion and the four common primate locomotor styles discussed in the lecture.
-Explain the scenario. Your team has discovered three primate limb bones and you have been tasked with determining the animal’s mode of locomotion.
-Thesis statement
Here is your googled definition of a thesis statement: A thesis statement is one sentence that expresses the main idea of a research paper or essay, such as an expository essay or argumentative essay. It makes a claim, directly answering a question.
Materials and Methods
-What are the elements you are working with
-What are the indices that you will be calculating
-how are they calculated
Results
-What are the index values
-Where do they fit in the plots provided in the lab
-which species do they plot with?
(feel free to copy and paste the scatter plots as well)
Discussion
General statement regarding this data and the overall locomotor pattern.
Discuss your findings beyond the simple locomotor classification (not just one of the four categories discussed above). There are low values and high values for each grouping. The differences reflect variations of that particular group. (this is explained in the lab content)
Explain the function of the indices. Why are the limbs built this way? What are the functional specifics? (explained in the lab content)
Can we make assumptions about body mass?
Conclusions
Assuming that the Mystery Primate is a known species, what species do your measurements suggest it is (refer to the scatter plots)? What sort of environment would you expect to find it in? Given its locomotor style and assumed body mass, what predictions could you possibly make about its diet? What other data would you need to confirm your predictions?

Assignment 9: Gravity
Instructor’s Overview
As you continue with your study of
physics, you'll learn that there are four fundamental interactions in
nature. These interactions are
summarized in this table:
Interaction
Comments
Relative strength
Effective range
Strong nuclear
force
Binds protons
and neutrons in nuclei

10-15 m
Electromagnetic
force
Force between

certain types of radioactive decay
10-13
10-18 m
Gravitational force
Force between
all objects. Determined by magnitude
of masses and separation. Follows
inverse-square law.
10-38
Infinite
So gravity is one of the four fundamental
forces of nature. We will learn about
the other three in Physics II. Some interesting things to note about the
gravitational force:
·
In a relative
sense, it is the weakest of the four fundamental interactions. Even so, gravity is largely responsible for
the dynamics of our solar system, galaxy, and the Universe as a whole.
·
Gravity acts over
an infinite distance. Objects may be
separated by thousands of light years, but they experience gravitational
attraction.
·
Gravitational
interactions obey the inverse-square law.
·
Coulomb's Law
dictating the force between two charged particles is also an inverse-square
relationship.
In this lab, you will perform experiments
that illuminate the concept of gravitational interaction.
This activity is based on Lab 10 of the
eScience Lab kit.
Our lab consists of two main
components. These components are
described in detail in the eScience manual.
Here is a quick overview:
Experiment 1: In the first part of the lab, you will subject
a variety of objects to the force of gravity and discuss your
observations.
Experiment 2: In the second part of the lab, you will use a
flashlight as an analogy to demonstrate the inverse-square law of gravity.
Take detailed
notes as you perform the experiment and fill out the sections below. This document serves as your lab report. Please include detailed descriptions of your
experimental methods and observations.

Based on your

Experiment
1: Falling in a Gravitational Field
The
following expression for the acceleration due to gravity works well for
objects near the Earth’s surface (G is the gravitational constant, Me
is the mass of the Earth, and Re is the radius of the Earth):
Use the
above equation to calculate the gravitational acceleration at an altitude
of 100,000 meters above the Earth. By what percentage is this acceleration
different from that on the Earth's surface?
How
does air resistance alter the way we perceive falling objects?
Using the universal law of gravitation, show that the
gravitational acceleration experienced by an object is independent of its
mass.

NOTE: Be sure to specify your units.
1.
How
did the intensity (brightness) of the circle of light seem to changes as you
increased the source distance?
2.
How
did the area of the circle of light change as you moved farther away? How does
this relate to the gravity field of a body?
3.
Make
a plot of distance vs. area for the light shining from the cup to the wall
(plot the area data on the y‐axis).
4.
Draw
a line of best fit through your data points, and comment on the general shape
of your plot. What kind of relationship
does this indicate (i.e. linear, exponential, logarithmic, etc.)?
5.
If
the amount of light shining from the flashlight is constant, the intensity of
light should decrease as the area it shines on gets larger. Using your plot from
question 2, sketch an approximate plot for light intensity vs. distance.
6.
If
you moved too far away from the wall the circle of light probably became very
difficult to see. Is the intensity of the light circle ever zero? Is it correct
to say that gravity doesn’t exist between objects on opposite sides of the
galaxy?

Franklin Pierce College Extra Terrestrial Biology Discussion
As an extra-terrestrial biologist, you discover a new species on another planet. You have confirmed that there are 3 different possible phenotypes regarding skin texture: individuals with all smooth skin, individuals with all prickly skin, and individuals with patches of smooth and patches of prickly skin. After doing some genetic research, you discover that for this species, the male is the homogametic sex and the female is heterogametic. You also discover that the gene for skin texture is on the Z chromosome.You bring an individual with patches of smooth and patches of prickly skin into the lab for further study. Your assistant, Jessica, says that the individual must be female. Your other assistant, Jose, says the individual must be male. Your 3rd assistant, Olivia, says it could be either male or female.1.Who is right? What is the sex of this individual? Explain your answer fully (note that there is more than one way to correctly answer this question so you must thoroughly explain your rationale).2.Explain the cellular/molecular reason why individuals with both alleles have patches of each skin texture, rather than a mixture of both textures.
