The correct option is D.
Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.
At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.
Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.
Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.
Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.
So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.

Answer:
A lethal mutation, thereby the resulting phenotype is not observed
.
Explanation:
Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

Explanation:
I wont be able to answer your full question due to that I don't know where your home is located.
<h2><u>Question 1</u></h2>
Four possible sources of energy in your home are:
Thermal Energy, like your microwave or oven
Solar Energy, solar panels if you have any
Wind Energy, like a fan blowing
Electrical Energy, like plugging in a device
<h2><u>Question 2</u></h2>
Probably, in our world today, your home would mostly be powered with one of the following:
Solar Energy: If you have solar panels installed. They generate a lot of energy for electricity.
Electrical Energy: Power Plants create electric energy that go through cables to millions of billions of homes. Electrical Energy is most people's main source of power due to electric companies providing it every second.
I will continue on, in order to answer Questions 3 and 4, your location is required.
Hope this helped! :)
