The answer is; graph A
Breathing increases during exercise because the body is demanding more oxygen for the muscles. The hypothalamus detects the increased carbon dioxide in the blood dur9ng exercise and its commands the lungs to breath faster and deeper. When exercise stops, the body is restored to resting through homeostasis.
Due to the need to have completely controlled experiments to test a hypothesis, science can not prove everything. For example, the scientific method cannot alone say that global warming is bad or harmful to the world, as it can only study the objective causes and consequences.
There are 3 main processes that carbon dioxide (co2) must go through :
Respiration - All plants and animals are able to release energy from their food using respiration. This can also include any other living organism out there.
Combustion - This is the process of burning fuel. This releases carbon dioxide into the open space.
Photosynthesis- Any sort of g<span>reen plant, such as flowers, can remove carbon dioxide from the atmosphere by using photosynthesis. </span>
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
