Answer:
If the postsynaptic cell is an interneuron that uses GABA as a neurotransmitter, the excitation of this cell will result in an action potential in its synaptic targets.
The answer is OPTION B (False)
Explanation:
<em><u>Some terms explained:</u></em>
GABA:
known as gamma-aminobutyric acid (GABA), is an amino acid inhibitory neurotransmitter that decreases the neuron's action potential. It is well known to inhibit the activity of signal-receiving neurons.
The neuron will not generate action potentials when the action potential drops below a certain level, thus not excite nearby neurons.
Action potential:
An action potential is self-propagating in nature, is the mode through which a neuron transports electrical signals. Action potential of a neuron has three main stages: hyperpolarization, repolarization, and depolarization. It occurs when the membrane potential of a specific cell location rapidly rises and falls and it electrotonically depolarizes the membrane of regions in front of it.
Answer:
Positively charged ions
Explanation:
Histones are a group of proteins with a N-terminal end of an amino acid, that binds to the DNA in the nucleus helping it to condense into Chromatin. DNA wraps around a core of proteins to initially form the NUCLEOSO ME structure, which is the basic subunit of Chromatin. Each nucleosome is made up of DNA coiled around two copies (2) of proteins- H2A, H2B, H3 and H4, to form a set of eight proteins called histone octamer.
Due to the phosphate group (PO4-) embedded in the DNA molecule, they assume a negative charge. The positively charged ions of the N(C) terminal end of histones which arise from the amino acid group they contain allows it to bind tightly to negatively charged DNA i.e. the more positively and negatively charged the histone and DNA are respectively, the tighter the binding.
Due to this property, the proteins that binds to DNA in E.coli, should possess a positive charge in similarity to histones in eukaryotes.
It’s called a negative feedback loop.
Insulin and Glucagon work in what’s called a negative feedback loop.
During this process, one event triggers another, which triggers another, and it keeps going, to keep your blood sugar levels balanced.
I hope this answers your question :)

The scientists should the one that decides that.
Scientists' main job is only one, to pursue the truth based on the researchers and analytical approach that they made (which will consume a lot of time and resources)
In order to fully do their job and maintain their commitment to the research, they need to be granted as much freedom as possible regarding which field of study that became their passion.
