In tube 1 the chloroplast solution was heated= photosynthesis increased then eventually decreased In tube 2 a herbicide was added= photosynthesis decreased In tube 3 the chloroplast was exposed to green light= photosynthesis decreased In tube 4 the chloroplast was exposed to red light=...

1. Will an enzyme function with with the heme (without the protein component) group only? 2. What is the is the importance of the heme group for enzyme activity?

1. If photographic film is placed in either active trypsin( pH2 and pH 7.4) or active pepsin, what would you expect to see happen to the protein coat on the photographic film? WHY? 2. Do pepsin and trypsin show any pH-activity relationship? Is so, what is the biological significance of this...

the weight of cats is normally distributed. It is known that 10% of cats weigh more than 1.8kg, and 15% of cats weigh less than 1.35kg. Find the mean and the standard deviation of this distribution.

(if u used ur calculator can you show me how) 1. A sale representative for a tyra manufacturer claims that the company's steel-belted radial tyres last 55000km. A tyre dealer decided to check this claim by testing eight of the tyres. If 75% or more of the eight tyres he tests last at least...

Energy and calorimetry? 1.What energy tranformations occur when the calorimeter and its content are being heated? 2.What would be the effect on the calibration factor obtained from this experiment if you used 50ml water instead of 100ml water to calibrate the calorimeter? 3. Energy is neither...

1. Find the probability that, in three tosses of a fair coin, there are three heads, given that there is at least one head. 2. The chance that a harvest is poorer than average is .5, but if it is known that a certain disease is present, this probabilty increases to .8. The disease B is present...

An oxy-acetylene welding torch uses ethene (acetylene) at the rate of 500ml per minute, measured at STP. The reaction is 2C2H2 + 502---> 4CO2+ 2H2O ; H= -2599kj mol-1 1. What is the heat of combustion of ethyne in kj mol-1 and kj g-1 2. Calculate the rate of enery production by the torch in...

In an experiment to examine the breakdown of starch by dilute hydrochloric acid and by an enzyme; we added iodine to the starch and HCl solution, then sodium hydroxide, before we added the benedict reagent. Why did the solution of starch and HCl have to be neutralised with sodium hydroxide...

Inverse Help Plz? 1. For f:R---->R, f(x) = 2e^x -4 Find the coordinates of the points of intersection of the graph of y=f(x) and y=f^-1(x) 2. For f:R----->R, f(x)= 2loge (x+3) +4 Find the coordinates of the points of intersection of the graph of y=f(x) and y=f^-1(x) 3. how do you...
