The amount of energy needed is 2093 J
Explanation:
The amount of energy needed to increase the temperature of a substance by 
is given by the equation
where
m is the mass of the substance
C is its specific heat capacity
is the increase in temperature
For the water in this problem, we have
m = 50.0 g = 0.050 kg
(specific heat capacity of water)
Therefore, the amount of energy needed is

Correct answer is:
<h2>The maximum number of orbits in an atom is <u>Seven.</u></h2><h3>Explanation:</h3>
Every energy level has a limited one orbital including two electrons. The orbits are settled in the sub-levels and there can be further than 1 sub-level as the number of energy levels rises. On energy level 1, there is 1 sub-level and 1 orbital. Energy level 2 can possess 2 sub-levels and 2 orbitals. These remain to develop as you progress from the nucleus of the atom, closing up with an infinite potential number of levels and orbits.
Answer:
The correct answers to the question are
The following statements about neurons are NOT true
A. The resting membrane potential is generally in the range of -40 mv to -75 mv.
C. Neurons repolarize by opening chloride channels on the membrane.
D. An action potential can occur when the neuron's sodium gates open.
Explanation:
A. The resting membrane potential is generally in the range of -40 mv to -75 mv.
Not true the resting potential for neurons range from -70 to -80 mv
B. Maintaining resting membrane potential requires the use of energy from ATP True
The potential of the membrane arises from the splitting of potassium ions from the intracellular anions by agents powered by ATP
C. Neurons repolarize by opening chloride channels on the membrane
Not True
Repolarization occurs by the outward transit of the positively charged K⁺ from the cell
D. An action potential can occur when the neuron's sodium gates open.
Not True
An action potential takes place once the neuron transmits information along an axon. An action potential results when different ions pass through the membrane of the neuron
