Answer:
In cellular respiration, carbon dioxide is formed from the oxidation of glucose molecule.
Respiration is also called energy releasing process. In respiration, oxygen is inhaled through the air into the body which combines with glucose which is present inside the cells. This combination of oxygen and glucose produces carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). Carbondioxode removed from the body through lungs and ATP is used for different processes.
The main and the most promising difference between active and passive transport is, passive transport does not require energy while active energy does.
Answer:
The correct answer is "a hypertonic solution".
Explanation:
Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
Answer:
The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen ... It sends out an electrical signal to start the contracting (pumping) of the heart muscle.
