Please explain the following questions in detail:
1. The introduction of gall flies to control invasive knapweed in montana permitted an increase in the numbers of deer mice. Apart from an increase in hantavirus in the area, what other effects might this have on the local community.
2. Explain how you might set a field experiment to determine whether insect pests are affecting crop yields. Be careful to include appropriate treatments and controls.
Do you think it is important for the survival of the human species to understand evolution? List three different ways that evolution can affect you personally in your lifetime.
What is anemia? There are different reasons triggering anemia and one of them is the lack of some micronutrients. What is/are those micronutrients? Why does/do it/they cause anemia?
With the limitation in glenohumeral joint motion presented in Part E, case 1, describe how you would improve the passive ROM measurement by stretching one of the tissues you have identified in this activity. Provide your rationale, review the previous lab activities describing the important aspects of stretching a tissue.
Case 1: A patient examination reveals that the range of motion measurement for PASSIVE shoulder internal rotation is 30 degrees.
Explain the molecular processes occurring inside a transcription bubble
In morning glory flowers, plants with red flowers can be homozygous RR or heterozygous Rr. Plants that are rr have white flowers. How can you determine the genotype of a plant that has red flowers?
A. Cross the red plant with another red plant, and then cross the F1 population with each other to see if any white plants appear.
B. The phenotype reflects the genotype, so the plant must be homozygous for the trait.
C. Cross the red plant with a white plant to see how many red plants appear.
D. Cross the red plant with a white plant to see if any white plants appear.
E. Cross the red plant with another red plant to see if any white plants appear.
Imagine that we are studying the colour coat of a population of chamoix in the Alps. There are two morphs, white and dark brown, which we know to be genetically determined.
(a) We observe that the frequency of brown decreased quite substantially between 2010 and 2011. Give 4 different potential explanations for this decrease
(b) Imagine that we observe that the frequency of brown varies erratically over the next 4 years. Give two potential explanations for the changes in the frequency of brown
VENTILATION/RESPIRATION: ANATOMY AND PHYSIOLOGY
1) Using Fick's law, explain why it is harder to breathe at the top of Mount Everest.
2) Using Fick's law, justify why the body surface of a Turbellaria makes a good respiratory surface for the worm.
3) Recall the gills seen in your crayfish, squid, and clam dissections. Was that tissue usually described as "feathery" or were they "dense" structures? From what you know of Fick's law, why does the characterization you use make sense?
4) What organisms have spiracles and why are they important for that organism?
5) How is air moved through tracheae in insects?
6) Order the airway passages and/or structures that air goes through starting from the nose to the blood stream in humans. (You should have at least five passages)
B) what is the main differences between those passage ways?
7) Provide at least two ways the anatomy of the lung helps to maximize Fick's law.
8) Describe how the diaphragm and muscles around the rib cage promote negative pressure breathing.
B) What type of animals use positive-pressure breathing and why might this be okay?
9) Describe at least two ways ventilation in birds is different from ventilation in humans.
You wish to develop an antitoxin therapeutic. Your plan is to create a molecule which will inactivate the ability of the toxin to penetrate the cell membrane, thus preventing the toxic effects. You decide to base the therapeutic on an aptamer design.
Eukaryotic cells require the concerted efforts of various transcription factors to carry out transcription.
1. Consider a glucose molecule that was taken up by aerobic eukaryote, anaerobic prokaryote and facultative anaerobe prokaryote cell- wheat will be the fate of this molecule? How will each of these cells metabolize it and how much energy will each get? Emphasize on what are the most important charcteristics of glycolysis, Kreb's cycle and ETC- what is starting substrate, what is product and where does it take place. 2.Give your OWN EXAMPLES of different types of enzymes and then explain these to describe their activity. microbiology I need reference page where you got the answer from. thanks
Which of the following are typically used to determine differences in DNA sequence between individuals? Select all that apply.
b) DNA fingerprinting of STRs
c) DNA sequencing
d) RFLP analysis
e) gel-filtration chromatograpgy
f) western blot
