Genetic engineers use the 3 methods of base excision,nucleotide excision and mismatch repair to remove human DNA for use in splicing bacterial DNA.
Hope that helps.
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:
Pretty sure it's A because people can redo this test as many times as needed to verify the answer.
Answer:
These characteristics are cellular organization , reproduction , metabolism , homeostasis , heredity , response to stimuli , growth and development, and adaptation through evolution.
Explanation:
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
Hope this helps!
