A volume of 120mL of H2O is initially at room temperature (22.0 degree C). A chilled steel rod at 2.00 degree C is placed in the water. If the final temperature of the system is 21.0 degree C , what is the mass of the steel bar? Use the following values: specific heat of water = 4.18 J/(g . degree C) specific heat of steel = 0.452 J/(g . degree C) Express your answer to three significant figures and include the appropriate units. Solution Q gain = Q lost 120* ...

11. Name a muscle from the anterior compartment of the upper leg? State its function. Identify a synergist and antagonist of that muscle. 12. Name a muscle from the posterior compartment of the anpagrenis? sftah its fionlefy a snergist and Solution s femoris is a muscle of anterior compartment of upper leg or thigh. It is attached to patella. It help in extension of knee,flexion of thigh and flexion of hip joint. Synergistic muscle-vastus medialis,vastus intermedius,vastus lateralis...

-Assuming you found that one cue elicited a faster response than the other cue how can you explain this using your knowledge about neurophysiology? This answer is the most important of all conclusion questions and should include, at the least, information about receptors (mechanoreceptors vs. photoreceptors), amount of synapses before entering the brain, and neuronal distance traveled from the relevant processing cortex to the motor cortex responsible for the physical reaction. -Given your ...

A population of bacteria may evolve resistance to a drug over time. This graph shows the growth of a bacterial population before and after the introduction of an antibiotic, with some bacteria becoming resistant to the antibiotic. Part B . Thinking critically Which three statements may correctly explain why the population size increases after time point C? Because the population grew more rapidly after time point C, the bacteria must have acquired a second drug- resistance mutation. 0 The ...

Assume you are given an unknown first-order RC two port network but are able to measure the magnitude and phase plots of its transfer function as shown in below: What common filter characteristic corresponds to these graphs? Draw the Bode plot for the unknown network and mark the break frequency and slope. What Is the transfer function of the RC circuit which leads to this response? Give the value for the break frequency and use a transfer function which is expressed in terms of this freq...

A diffraction grating that has 2000 lines per centimeter is used to measure the wavelenghts emitted by hydrogen gas. At what angles in the first order spectrum would you expect to find the two violet lines that have wavelengths of 434 nm and 410 nm? What are the angles if the grating has 15 000 slits per centimeter? Solution Hi, there is no question here. It might not have loaded properly. Request to re-post and rate this one. You may post it as an image or text. Th...

11) A scientist found that strain K of the organism Enterobacter aerogenes produces a restriction enzyme. This is the third restriction enzyme to be identified from this organism. What name will this enzyme receive? 12) Restriction enzymes cut DNA and create a) blunt ends b) sticky ends c) one sticky end and one blunt end electrode because 13) When in an electrical field, plasmids will travel toward the a) negative; because the bases have a positive charge. b) negative; the positive charge ...

22) Using the gene diagram below, which statement is true? L108 bicoid caudal tailless hunchback- kruppel knirps giant even-skipped Solution A is wrong because caudal is regulated by both hunchback and bicoid. C is wrong because kruppel is not negatively regulated by evem-skipped. D is wrong because kruppel negatively regulated hunchback. B is correct because kruppel is regulated by 4 proteins. Hunchback and bicoid positively regulates kruppel and giant and tailess regulates kruppel...

Anatomy of urinary system Anatomy of urinary system Solution Anatomy of urinary system The urinary system involves kidneys, ureters, urinary bladder and urethra. The kidneys are a pair of bean shaped organ located along the posterior wall of abdominal cavity. A tube is arised from each kidney called ureter which carry urine from kidney to the urinary bladder. The ureters are 10 to 12 inches long, runs parallel to vertebral column. Ureterovesical valves are present...

4. Brain cells depend on glucose for energy and use GLUT3 (a glucose transporter) which has a Km of 1.5 mM, Liver cells use a different glucose transporter, GLUT2 which has a Km of 15 mM =Vmax [S] S] + KM Glucose levels in blood (mM) Starvation conditions Normal level After high carbohydrate meal 5 15 Using the equation and information provided in table above; Compare the rate (as percentage of Vmax) of glucose uptake in both cell types (brain and liver) a. under starvation conditions. b.
