Answer:
The correct answer will be option-A
Explanation:
The respiratory system is the series of organs which is links the internal gases with atmospheric gases that is it is responsible for the exchange of gases in the animal kingdom.
The respiratory system involves the intake of oxygen and exhalation of carbon dioxide as a waste product.
The primary organs involved in the respiratory system are the lungs which along with the circulatory system transports the oxygen to every cell of the body.
Since the respiratory system along with the circulatory system allows the transport of oxygen to every cell therefore, option-A is the correct answer.
When combined the dominant one takes over. Therefore, you see the dominant trait physically, not the recessive one. However, genetically, they are both there.
The rate of movement was observed in this experiment as 0.25 m/ hour.
<h3>How, explain your answer?</h3>
A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.
o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.
We know that took 2 hours. so we just have to calculate that:
0.5 meters / 2 hours = 0.25 m/hour
Thus, The rate of movement was observed in this experiment as 0.25 m/ hour.
