It is a series of compounds especially organic compounds with the same general formula or functional group that differ by - CH₂ with similar properties.
Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.
Humans internal body temperature is a great example of homeotosis.
The answer would be B:The data suggests that exercise increases the rate of cellular respiration because more carbon dioxide was produced.
The data has a consistently show that the time needed to change BTB color in after exercise group is much shorter(less than half) compared to before exercise group. If the time needed longer, this show that the amount carbon dioxide removed from the lungs is much higher. The reaction that provide energy for the muscle will produce carbon dioxide as side product in cellular respiration.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
