Homework Answers
The rate of transpiration by the plant decreases when the humidity of the surrounding air increases.
Explanation:
Rate of diffusion of a substance depends upon the concentration gradient between the two regions. Transpiration occurs due to diffusion of water in the form of vapours from the plant green parts which contain stomata to the surrounding air. If the surrounding air has more water vapour. I. e, have high humidity, the rate of diffusion of water vapour from the plant surface, called transpiration will be lower, because there will be lesser vapour gradient between the plant surface and the surrounding air.

10.24 Estimate the error contribution to the uncertainty in flow rate due to the effect of the relative humidity of air on air density. Consider the case of using an orifice plate to meter air flow if the relative humid ity of the 70 Fair can vary from10% to 80% but a density equivalent to 45% relative humidity is used in the computations.

A researcher would like to determine whether humidity can have an effect on eating behavior. It’s known that under regular circumstances laboratory rats eat an average of μ=10 grams of food each day, with standard deviation σ=2. The researcher selects a random sample of n=16 rats and places them in a controlled atmosphere room where the relative humidity is maintained at 90%. For these rats in humid atmosphere, the average daily food consumption is 13 grams. The researcher tests at...

4. Dr. Luis designed an experiment to determine the effect that ethylene has on the growth of the Justicia mirabiloides plant, an endemic plant in Puerto Rico. For this, Dr. Luis made sure that all the plants (5 plants) in the experiment were under the same conditions, such as: pots, soil, temperature and humidity. However, Dr. Luis did not have the expected results. What would be a possible explanation for the doctor not obtaining the expected results?(choose the best option)...
Suppose expected future prices fall. What effect would this have in the graph?
Consider the demand for a good illustrated in the figure below. Suppose expected future prices fall. What effect would this have in the graph? This would result in a slide down the demand curve. This would result in a slide up the demand curve This would result the demand curve shifting to the let This would result the demand curve shifting to the right 09 0
