During exercise, muscle cells immediately use ATP as the energy source for contractions.

The only immediate source of energy for muscular contraction is ATP. Within muscle fibers, ATP is replenished by creatine phosphate (anaerobic respiration), glycolysis (anaerobic respiration), and cellular respiration (aerobic respiration). As the duration and intensity increase, carbohydrates (glucose/glycogen) become the primary source of fuel. If exercise is sustained for an extended period of time, fatty acids will be used as a fuel source when glycogen stores are nearly depleted.

ATP is a form of instant energy. The body cannot obtain energy directly from glucose. Glucose is not a direct source of energy. Instead, the body uses the energy released from the breakdown of glucose to drive ADP phosphorylation.

Zoe read that drinking water from a faucet instead of from a plastic bottle helps overcome a disadvantage of using nonrenewable
pentagon [3]

Answer:

Plastic is made from petroleum oil.

Explanation:

A faucet can simply be described as a tap or valve through which the releasing of a certain liquid can be controlled. Whereas a plastic is made from non-renewable resources such as petroleum oil. Also, the plastic cannot be properly degraded from the Earth after using it. Hence, drinking water from a faucet is more beneficial then drinking water from plastic bottles.

Vlada [557]

The hypothesis devised in this study by the researcher is –  

" White fly nymphs escape predation because of their translucent bodies."

In order to test this hypothesis, the researcher is required to conduct an experiment where two sets of white fly nymphs are formed and fed to their predators. The two set of subjects would be -  

Set I – White fly nymphs with translucent bodies  

Set II- White fly nymphs with translucent bodies coated with harmless dyes.  

The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.  

Hence, option B is correct
