Part A A scientist compares a whole woolly mammoth fossil to a modern-day elephant. How can the scientist use this fossil to show how closely related the woolly mammoth is to the elephant? A. The scientist could compare the lifespans of both animals. O B. The sciently could compare the migration paths of both animals. C. The scientist could compare the shapes of bones in both animals. D. The scientist could compare the habitats in which both animals lived.​

Which one of the following research methods can show cause and effect

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
