<u>BINARY FISSION</u> describes a process when a bacterial cell divides to produce a new cell.
Answer:
The respiratory system aids the supply of oxygen to the blood and the evacuation of carbon dioxide. when the heart takes in blood that as shortage of oxygen and abundance of carbon dioxide, the pulmonary arteries pumps such blood to the lungs.
As the lungs increases due to inflow of fresh air from the surroundings, oxygen is transported to enrich low-oxygen blood, and transport the carbon dioxide out of the lungs.
This freshly oxygen rich blood which now have a rich amount of hemoglobin is transported to the heart which then pump or circulated it to the entire body.
The pH of blood if pco2 drops to 35.0 mmHg is 7.459
The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.
pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )
pK is 6.1 for the bicarbonate buffer system.
HCO3- = 24mm
PCO2 = 35.0 mmhg
pH = 6.1 + log ( 24 / 0.03 * 35.0 )
= 6.1 + log ( 24 / 1.05 )
= 6.1 + log 22.8571
= 6.1 + 1.3590
= 7.459
Hence, the pH of blood is 7.459

Answer:
Mechanoreception
Explanation:
Mechanoreception is usually defined as the ability of an organism, such as humans and animals, to perceive and react to certain types of stimuli. This may include a sensation like sound, touch, that are produced in an environment.
This involves the conversion of sound waves (which are mechanical vibrations) into nerve impulses which are in the form of electrical signals. Initially, this process starts with the vibration of the eardrum and immediately transmits these vibrations towards the three small bones that are located in the middle portion of the ear. These are then carried by the auditory nerve into the brain. The brain finally converts this information into electrical signals. This entire process eventually leads to the creation of sound within the temporal lobe inside the brain.
<span>Because there is a lack of sufficient oxygen in muscle cells. For muscle cells to convert pyruvate into usable energy (ATP), there must be a sufficient amount of oxygen available to the cells. When there is not, the body has the ability to convert it to lactate which can provide energy when little oxygen is available.</span>
