Assume that you are trying to identify an unknown organic molecule. it contains only carbon, hydrogen, and oxygen and is found in the cell walls of a newly discovered plant species. what type of organic compound is it? why?

A carbohydrate

Explanation:

Carbohydrates, also known as sugars, are molecules with a chemical composition made of only carbon, hydrogen and oxygen, their general formula is (CH2O)n.

Apart from its composition, we have to consider that plant cells have walls composed of polysaccharides such as cellulose that is made of many carbohydrates together.

I hope you find this information useful and interesting! Good luck!

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
