Hello! Here are a couple of major events that happened in the Mesozoic Era.
1. The Mesozoic Era began with the largest mass extinction in history, killing off the vast majority of marine and terrestrial life on Earth.
2. After that mass extinction, the super continent Pangaea began to break off, and the dinosaurs began to flourish the Earth, although they were killed off at the end of the Mesozoic Era.
Answer:
The correct option is (D). GLUT1 deficiency syndrome belongs to the category of autosomal dominant disease. This genetic disorder limits the transport of glucose to the brain as the aforementioned proteins helps in the process.
Explanation:
A separating membrane is formed in between the blood and the brain and also the extracellular fluid of the central nervous system that is more specifically known as the blood-brain barrier. Some of its major functions include restriction of the passage of the antigen or pathogen, solute diffusion in the blood. The protein GLUT1 helps in the glucose transportation in the brain as it is able to cross the blood-brain barrier. The associated gene resides on chromosome number 1 is called SLC2A1 gene.
Mutation in this gene leads to less or no production of the protein and hence the glucose transport process to the brain is hampered. This affects the normal functioning of the brain as glucose is the major fuel for the brain.
