A student finds out that he has overslept has only 30 min to reach his class to take a test. Which part of her autonomous system would get activated and how will it help her deal with the situation Explain.(3) Solution During stress sympathetic system gets activated, produces norepinephrin. Due to stress, flight or fight hormone gets produced. During a fight against stress, adrenal gland gets activated. Adrenal gland activity leads to increase in heart rate and energy levels get eleva...

are the most abundant heteropolysaccharides in the human body. They are highly (b) charged molecules and one from structure to form containing repeating disaccharide units of one (o They extend (e) peptide core in a ( which are linked by a specific tetrasaccharide units. Solution a)Glycosaminoglycans (GAGs)- long unbranched polysaccharides found mainly on cell surface or in the extracellular matrix (ECM) b)Negatively- which helps in take up of Ca2+, Na+, K+ etc. c) Amino sugar [eith...

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. N...

4. which starting material is the limiting reagent in this procedure? which reagent is used in excess? hwo great is the molar excess (how many times greater)? Solution Here is the answer is (4) Isoamyl alcohol is the limiting reagent in this procedure acetic acid is used in excess and two times greater than molar excess than isoamyl alcohol

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...

5. You are studying a mutation in mice, which acts dominantly. Mice that have only one copy of the allele carrying this mutation have a kinky tail phenotype You identify the gene that the mutation affects and find that the codon that encodes the second amino acid in the predicted protein has been mutated to a stop codon. Would you characterize this mutation as a loss-of- function or a gain- of-function and what specific subtype (hypermorphic, antimorphic, etc. ) within these categories? Exp...
