Explanation:
Earth's Orbit = 2*pi*R = 942,000,000 kilometers.
Distance/Time = 942,000,000 km / 8766 hr = 107,000 km/hr = 30 km/sec.
Answer:
oligodendrocytes
Explanation:
Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons. These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.
It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.
a cell adapts using natural celection in the long term
in the short term, look at this Wikipedia article.

95% sure it is answer B) Detect the electrical discharges of prey in the sand using small pits on it's bill, crush the food with grinding pads on the top and bottom of it's bill (they don't have actual teeth), and webbed feet.
I did some quick research and it had all of those things.
Hope this helps.
