The circuit has to be closed, so B.
If the circuit was open, the flow of energy wouldn't be able to reach the light bulb.

What might happen if cytokinesis were omitted

Georgia [21]

Answer:

Explanation:

Cytokinesis is the process by which the cytoplasm splits, forming two daughter cells from one parental cell. It occurs towards the end of mitosis, after the DNA has been replicated. The process of mitosis generates a cell with two nuclei, and cytokinesis ensures that each daughter cell receives one nucleus.

Without the process of cytokinesis, the physical process of the production of two cells from one parental cell would not occur, so the cell would not divide into two daughter cells.

Astrocytes A. all of these B. induce the formation of the blood-brain barrier C. physically support neurons D. are important in

Keith_Richards [23]

Astrocytes perform the function of all of the given options i.e., induce the formation of the blood-brain barrier, physically support neurons, are important in the repair of brain injuries and in neural formation, take up excess K from the brain ECF.

Both invertebrates and vertebrates have Astrocytes, a star-shaped cell kind of neuroglia, in their nervous systems.
Astrocytes can be separated into protoplasmic and fibrous kinds. In the central nervous system's white matter, myelinated nerve fibers are frequently surrounded by fibrous astrocytes.
Numerous cytoplasmic processes on astrocytes end on axons, neuronal cell bodies, blood vessels, and synaptic terminals.

b) The development of the blood-brain barrier is aided by the Astrocytes

c) Astrocytes support neurons physically and metabolically.

d) Astrocytes help in transfer of blood-borne materials to the neuron, and injury response of the brain and repair of brain injuries.

e) They also help with detoxification, migratory guidance, energy metabolism regulation and removal of excess K from brain ECF.
