The air is warmer and less dense than surrounding air at the equator because the equator receives more solar energy.<span />
Answer:
The correct option is b. "IEC Na+/glucose symporters are found only in the plasma membrane (PM) facing the basal extracellular fluid"
Explanation:
The glucose in the intestine is a product of digestion and needs to be absorbed into the blood so it can be transported to where needed. Glucose moves out of the IEC with the combined action of sodium ions. The sodium-glucose symporter opens and allows for this pair to move out only when one of each is attached to the symporter. The movement of glucose is regulated in this way.
Bacteria that have
taken up the plasmid with antibiotic resistance
gene will grow in a medium laced with the particular antibiotic of interest. More
so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments
are used with selective media that only allows the bacteria with a particular characteristic
to grow.
In the spinal cord the central canal is lined with ependymal cell and contain cerebrospinal fluid. central canal is a conduit that runs the entire length of spinal cord. Ependymal cell plays an importance role in production and regulation of cerebrospinal fluid.
