In the images below: Foal A is 5 weeks old with a mild to moderate left carpal valgus that has developed progressively despite corrective trimming.  Foal B is 9 months old with a moderate to severe right carpal valgus that has only had minimal corrective trimming.  Based on the deformity you see present, the patient, and the history, which set of recommendations would you propose to produce the BEST result and least risk to the patient?    

Gathering information just to add to the knowledge base, such as measuring the beak length of various bird species, or determining the top speed of a cheetah is known as ________.

Which of the following is/are independent variable(s) in this experiment?

Use the following information to answer the next 5 questions. You perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gram of ammonium nitrate per liter of water and the other half receive only water. Each group is then split in half again, and exposed to either 8 or 16 hours of light each day. You monitor the height of the plants for 4 weeks. You observe that plants grown in ammonium nitrate and 16 hours of light grow taller than no ammonium nitrate and 8 hours of light.

In this experiment, the size of the pot is

Write a proper hypothesis for the above experiment.

Which of the following is/are dependent variable(s) in this experiment?

Match the following characteristics of living things with the definition.

You are a scientist in a biotechnology company that produces custom engineered tissues for patients. Your current project is to develop a cartilage replacement for a 30-year-old athlete with osteoarthritic joints. At the team meeting, you propose using mesenchymal stem cells isolated from the patient for this project. A colleague suggests using stem cells isolated from the Wharton jelly of the umbilical cord. 1. What advantages (provide 2) does using the patient’s mesenchymal stem cells offer over the umbilical cord-derived cells? (4 points) 2. After discussions, your team decides to use the patient’s mesenchymal stem cells, what steps will you use to isolate these cells? Assume you have the bone marrow aspirates (6 points) 3. After initial test isolation, you perform a viability assay and discover that 80% of the isolated cells are dead. What could have caused this problem and how do you remedy it? (6 points; 3 points for the problem, 3 points for the solution)

Some bacteria can exchange genetic material horizontally. Horizontal gene exchange refers to:
