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.
Your answer is A. during an extended surgical procedure
Energy is always lost as energy is moved from one level to another. ... The loss of energy due to the second law of thermodynamics results in a pyramid with a large base and a 10% ratio between levels.
Fat digestion yields fatty acids and glycerol. Protein digestion yields amino acids. Both digestive processes B. add a water molecule to break bonds.
Adding a water molecule to break bonds in fat digestion yields fatty acids and glycerol. Protein digestion yields amino acids in the digestive process.
Addition of the water molecules to break bonds is called as Hydrolysis. It is done in Fat digestion in which a water molecule is added to yield Fatty acid and Glycerol. Fatty acid is the forming component of fat in the body.
Addition of water molecule in Protein causes its absorption in the body during the digestive activity by forming amino acids that are simpler to absorb. Amino acids make up protein by forming chain of peptide bonds.
It similar to the reaction used in the breaking of bonds in carbohydrates. Proteases is the enzyme which is hydrolytic in nature carrying out hydrolysis.
Hence, the correct option is B. add a water molecule to break bonds.
