Answer:
Explanation:
Leison is what is been seen in the brain as white Spot it is as a result of activities carried out in the brain. MR monitors how blood flows into a part of the brain will then transfer the lesion into the brain.
Myaline sheets surround the nerves cells forming a layer round the axons.
Break down of Myaline sheathe leads random shot of neurons this then result in white leison. The leison disappers after the myelin sheat have been healed or repaired by the actions of the neuron present.
Neurons then carries signals or impulse that the myelin sheat have been fixed.
Answer:
Option C, Ketone body synthesis
Explanation:
Ketone bodies are used as a source of energy when glucose is not easily available as energy source. This usually happens when a person is fasting and hence does not intake any glucose. There are three main ketone bodies a) acetoacetate, b) 3-beta-hydroxybutyrate and c) acetone. When our body do not receive food for a long time or a person undergo rigorous and continuous physical exercise, then the level of ketone bodies increases in the blood
Hence, option C is correct
D) All of the above
Explanation:
Genetic engineering "allow scientists to create their own mutations in the organisms" by "manipulating the genetic code in attempt to improve a species" which is virtually the same as"altering genetic material".
Answer:
8-kb
Explanation:
As you can see in the picture attached, the cutting sites are consecutively situated in the genome. For that reason, if the largest fragment results when A and B cut, and the cutting site of C is betwen A and B, then the fragment expected from a digest with A and C could be calculated as follows:
