Which statement about an animal’s nervous system is true? Signal transmission rate is relatively slow Neurons form highly discrete lines of communication Action potential signals degrade over distance Neurotransmitter is released throughout the body via the blood
If your intake was higher in soluble fiber it would impact your health in the following way(s): increase transit time of food through Gl tract increasing risk for constipation control blood glucose levels reduce blood cholesterol levels
Describe the structure of DNA. Relate this structure to DNA’s functions. Describe specifically how proteins are created from the information encoded in DNA. Be sure to use the terms gene, mRNA, and ribosome.
Using the Nernst equation, calculate the equilibrium potential for the sodium ion if the concentration of sodium outside is 130 mM, and the concentration of sodium in the cytoplasm is 12 mM. Show your work.
Please discuss the major types of organic molecules of the human body. Then, compare and contrast the kinds of chemical bonding exhibited by secondary and tertiary levels of protein structure. Use illustrations to support your discussion points. 1. Your original post must have a clear understanding of the topic and should be a minimum of 1 paragraph with at least 5 sentences
2. You must respond to the posts of any 2 students. The responses should be a minimum of 1 paragraph with at least 3 sentences. You must start a thread before you can read and reply to other threads
Problem 2.Part 2 (14pt) Now add the reserved urea solute to the Total Body solute. If there areurea/l in 2 liters how many total mOsmoles of urea should be added to the solute block of the Total Body column?
506 mbsmbl Next recalculate the final osmolarity of the total body column. Carry that concentration across to the ECF and ICF compartments.
Note that Urea will distribute itself throughout the body until its (the urea) concentration everywhere is equal, but it will not cause any water shift between ECF and ICF. So will the ECF and ICF volumes change from those calculated in Part 1 of Problem 2?
Finally calculate the final solute mOsmoles (total ofand Urea) in the solute blocks of ECF and ICF usingAnswer the following questions from the values in this final table: a. What happened to the body osmolarity after adding the solution?
b. This result means that the added solution was – osmotic to the body’s starting osmolarity. c. What happened to the ICF volume? d. This means that the added solution was -tonic to the cells.
Name the 3 meninges. Which of the meninges is found in the middle of the other two? 2. What is the difference between a gyrus and a sulcus? 3. What fluid is found in the ventricles of the brain? From the cerebral aquadect, where does this fluid flow to next?
4. Name the lobes of the cerebrum. What are the main functions of each lobe? Ie what sense does the temporal lobe interpret?
5. What function does the precentral gyrus have? 6. What function does the postcentral gyrus have? 7. What structure physically connects the cerebral hemispheres?
Which biological macromolecule is composed of glycerol and fatty acids and is mit a polymer? a, trielyceride b. protein c. glycogen d. DNA
7. Glocose is stored as which molecule within the liver and skelctal muscie rissue? a. starch b. phospholigid c. glycogen d. elucapon 8. Which of stse following is a comrion anion of the haman body? a.b. P”c.d9.
Weat is the intermolecular aitractios between polar molecules? a. Tydrophobic inseractions b. ly deopes bonds c. van der Wals kateen i. Wanic tonds
Your report needs to have a labelled Results section where you summarize your data from Part 1 into a table, your data from Part 2 into a bar graph comparing the metabolic rates of the baseline rats and rats injectepl with thyroxine, your data from Part 3 into a bar graph comparing the metabolic rates of the baseline rats and rats injected with thyroid stimulating hormone (TSH), and your from Part 4 into a bar graph comparing the metabolic rates of the baseline rats and rats injected with propylthiouracil. Each table and graph needs a short description, but not explanation, highlighting important observations.
follow the instructions pls 🙂
