Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly. </span>
Answer:
I think it is the scientific method.
Explanation:
Sorry for that lack of info.
Answer:
Y is probably excitatory and Z is probably inhibitory
Explanation:
- Two neurons communicate with each other generally by releasing neurotransmitters.
- The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
- Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
- The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
- From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.
