Answer:
as electrons move through the electron transport chain they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water). Energy released in the electron transport chain is captured as a proton gradient, which powers production of ATP by a membrane protein called ATP synthase
Major discoveries are usually confirmed when more than one person does an experiment about it and the experiments both yield the same results.
The plants were providing the necessary oxygen for the animals to breathe and the animals were serving as an aide in photosynthesis for the plants by producing carbon dioxide.
Answer:
Basically, most antibiotic drugs are not effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of diameter of the bacterial growth . <u>This is because the diameter is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a measure of how effective it can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control the bacteria, While a large diameter is an indication of low effectiveness of the drug.
Based on this analogy, penicillin with wide usage for control of bacteria growth with diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm or 6mm depending on type of bacterial.
Therefore, the least 3mm diameter presented by penicillin is an indication that , antibiotic drugs are not effective enough, and further research need to be done to control growth of bacteria and therefore its pathogenic effects.
