Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system

Answer:
DNA is made of chains of four smaller molecules called "Nucleotides".
Explanation:
A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine) in DNA is known as a nucleotides.
The Gardener removes the apical bud
-the amount of the hormone that inhibits shoot elongation begins to decrease in the lateral buds
-the balance of hormones in the lateral buds shifts in favor of growth
-the memberlist cells in the lateral buds begin to divide
-the plant grows shoots which elongate into branches from the lateral buds
plant becomes bushier
