The correct answer is d. both excitation and inhibition.
There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).
Answer:
Volume
Explanation:
The boiling point and density of water never changes, no matter how much you add
So the answer CAN'T be Boiling point or Density
Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>
So it CAN'T be Electrical Conductivity
It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture
I think it's D, because those are sexual reproduction cells!
Answer:
The correct answer will be option-C
Explanation:
Louse-bourne relapsing fever is a disease which is characterised by having the muscle aches and the episodes of fever.
The disease is a vector-borne disease in which the pathogen spirochete <em>Borrelia recurrentis</em> which lives in the gut of the body louse- <em>Pediculus humanus humanus </em>completes its life cycle and when body louse is crushed gets released on to the human skin and thus penetrates the humans. The disease could prove fatal if no treatment is provided at the right time.
Thus, Option-C is the correct answer.
The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.
