Answer:
False
Explanation
When air flows into the lungs, the process is known as inspiration. During inspiration, expansion of the lungs occurs due to the contraction of external intercostal muscles and the relaxation of internal ones. Expansion of the lungs allows the increase of alveolar volume due to which alveolar pressure decreases. When alveolar pressure becomes significantly lower than the atmospheric pressure, air flows into the lungs, to balance the air pressure.
Alveolar pressure becomes equal to atmospheric pressure only at the end of expiration. As air pressure remains equal on both sides, no movement of air occurs.
Answer:
The correct option is A. It is the largest single structure created by organisms and is the largest coral reef in the world.
Explanation:
The Great Barrier Reef comprises of about two thousand and nine hundred reefs. This Great Reef covers an area of about 900 islands. The Great Barrier Reef is such huge that it can be seen from the outer space. Millions of tiny organisms which are known as corals polyps make up the Great Barrier Reef. The Great Barrier Reef is a wonder because it is the largest single structure made by humans and hence its name was suggested to be among the natural wonders of the world.
The light-dependent reaction<span> takes place on the thylakoid membranes</span>
Answer:
yes
Explanation:
light is main source of energy for photosynthesis to take place
if you recall photosynthesis cannot take place without light
even in dark reaction , light reaction has to produce ATP and reduced NADH which dark reaction will use .
