It allows scientists to explore new explanations for observations.
Answer:
As the spies of a cactus are modified leaves, they have ar spaces.
Explanation:
However, leaves of cactus are not like every other leaf. These leaves are in the form of spines to save the amount of water that the cactus needs.

It was the trip that Charles Darwin went on in attempt to find the answer of how animals got on earth in the first place and how they changed over time.

Smaller beaks meant the finch ate more small nutrients but larger beaks meant the finch ate more harder prey such as fish and worms.
Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
<h3>What increases stroke volume?</h3>
A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
