Answer:
The correct answer will be option-B
Explanation:
Locus coeruleus is a nucleus composed of neurons in the pons region of the brainstem. The pons and brainstem are involved in the physiological responses of panic and the stress conditions.
Nor-epinephrine is the hormone which is produced in the stress and fear conditions and produces fight or flight response. The nor-epinephrine is produced from the adrenal medulla in the kidney and the brain. The part of the brain involved in the production of Nor-epinephrine is locus coeruleus.
Thus, Option-B is the correct answer.
Answer:
The structure of each cell type's wall.
Explanation:
The basis of Gram stain is differentiating cells in two different categories depending on the composition of the cell wall. Gram positives fixate a KI and Crystal Violeta complex in their peptidoglycan wall, but otherwise, gram negatives don't have a thick layer of this, and therefore, when the wash process happens it takes away all the pigments leaving the cells blank for the last pigment (pink).
The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.
Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.
Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.
With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

Answer:
I believe I have had this question this before. The correct answer should be rr, BB.
Answer:
Neurotransmitter
Explanation:
A neurotransmitter is a signal which transmits information between neurons at the end of the axon. This neurotransmitter can either be excitatory or inhibitory. Whenever an action potential is triggered within a neuron, the neurotransmitter releases this action potential into the synapses at the axon as either an excitatory or inhibitory signal before a new action potential is triggered.
