Conduct an experiment using an ectotherm (a cricket) to explore the effect of temperature on cellular respiration c. Measure changes in respiration rates of a cricket d. Design an experiment to measure the heart rate, pulse and blood pressure of a cricket e. Measure your heart rate, pulse, blood pressure under different environmental conditions

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
