Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.
When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.
The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.
When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise
Answer: The answer is C. An iron atom located on the heme portion hemoglobin
Explanation: Hemoglobin is responsible for the transportation of oxygen in the red blood cells to tissues of vertebrates. It is the protein molecule found in the red blood cells.
Hemoglobin is made up of 4 heme molecules surrounding the globin group, forming a tetrahedral structure. The heme molecules contain one atom of iron each and this is the binding spot for each molecule of oxygen through a covalent bond. Therefore, each hemoglobin molecule can have up to four molecules of oxygen attached to them.
Power is defined as Work / Time.
With this formula, we can solve.
As of now, we are looking for the power
P=
We have 2,000J of work and 80s (simplified into seconds).
2,000 / 80
Rewrite our transitions into an equation.
P = 2,000 / 80
Divide 2,000 by 80.
2,000 / 80 = 25.
Your answer is:
25W (W is the unit for Watts)
I hope this helps!
Answer: the heart pumps blood throughout the body through arteries, vessels, and veins.
Explanation:
Explanation:
Minerals are solid substances that are present in nature and can be made of one element or more elements combined together (chemical compounds).
