Answer: E) provide the defense for the CNS
Explanation:
Astrocytes can be defined as one of the cell types in the central nervous system. These are the dominant glial cell found in the brain. These cells perform a variety of functions in the brain. The functions includes axon guidance, synaptic support, controlling the blood brain barrier and blood flow. These cells maintain the chemical environment in the brain especially around the neuron.
These cells do not provide to the central nervous system.
Answer:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)
Explanation:
Neurotransmitters are defined as the chemicals that is transported from a nerve cell across the synaptic gap to the receptor of another neuron or a target cell such as a gland cell or a muscle cell.
Neurotransmitters are generated in the central nervous system (the brain and spinal cord) and are stored in synaptic vesicles.
"Hence, the correct answer is:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)".
Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
Answer:
Reaction 1
Explanation:
Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.
