Answer: 60 to 100 beats per minute.
Explanation:
Pulse is the number of times the hear pump blood out into the systemic circulation per minute
The lower this range the more efficient the heart is. In trained athletes the pulse rate is about 40bpm.
This shows the heart pumps blood at a faster rate to meet the demands of the muscles and other organs involved in the strenuous activities.
It can be measured by placing two fingers on the thumb side of the wrist,and count numbers of beats heard for 15 seconds.The counted number should multiplied by 4 to obtain beats per minute.
Answer:
The correct answer would be B. The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy.
Respiratory system and cardiovascular system work together in order to provide oxygen to each cell of the body. They also help in removing the carbon dioxide (produced by cellular respiration) out of the body.
Respiratory system transport oxygen from outside the body to the alveolar site (in lungs). Oxygen is then carried in dissolved form with the help of hemoglobin (red blood cells) to all parts of the body.
Blood also carries deoxygenated blood (high carbon dioxide content) from all the cells to the alveolar site. The carbon dioxide is then excreted out of the body with the help of the respiratory system.

The high coastal zone presents the greatest abundance of marine organisms.
Where are most marine organisms found?
Most ocean life can be found in coastal habitats on the continental shelf, despite the fact that this area represents only 7% of the total area of the ocean. Most open ocean habitats are found in the deep ocean beyond the continental shelf. Species that live in oceans and along shorelines can help create new habitats.
The intertidal zone, also known as the "littoral zone", refers to the shoreline that is covered at high tide and exposed at low tide, revealing a unique biome that survives in such fluctuating conditions.
