If you wanted to increase your muscular endurance, it would be important to participate in activities that . A.
increase the size of the muscle cells and the amount of blood that is delivered to the muscle
B.
decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract
C.
increase the number of muscles and decrease the size of the muscle cells
D.
decrease the length of the muscle and increase the thickness of the muscle

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Answerthe global climate during the paleogene departed from the hot and humid conditions of the late mesozoic era and began a cooling and drying trend which dispite having been periodically disrupted by warm periods such as the paleocene-eocene thermal maximum, persists today;

B? i think so but hope that's right and answers your question
