It is useful for the walls of capillaries to consist of a single layer of thin, flattened cells in order to easily diffuse oxygen and nutrients easily from the blood and into the capillaries. Not only that, but this also makes it more efficient for carbon dioxide and other waste molecules to diffuse from the capillaries and into the blood. If capillaries were thicker than a cell, then it would be more difficult for materials to diffuse through the thick layer of cells.
A river of air called the jet stream runs along the troposphere just near the top. The troposphere starts at ground level and rises 11 km up which is equivalent to 7 miles or 36,000ft.
About 3/4 of the air in our atmosphere is in the troposphere and almost all weather happens here. Most of the clouds are found in the troposphere layer.
The jet stream is found just near the top of the troposphere zooming along at a speed of 400km/hr (250 miles per hour)
Answer:
It is due to the temperature of the star
Explanation:
The colour of star depends on the temperature of star.
Answer:
The correct answer is c aerobic respiration
Explanation:
The process glycolysis,TCA cycle and electron transport chain are additionally called Aerobic respiration.
Glycolysis occurs in the cytoplasm and deals with the catabolism or break down of glucose in a sequence of enzyme catalyzed steps to form pyruvate and ATP.
TCA cycle occurs in Mitocondria.This metabolic process helps in the formataion of ATP along with the oxidation of glucose to generate CO2 and H2O.
Cephalochordata is the subphylum that retains all chordate characteristics, even in the adult forms.
