Answer:
1. The oxygen deprived cardiac muscles caused chest pain.
2. Unavailability of oxygen and blood supply to skin cells made them pale and cold.
3. Accumulation of blood in pulmonary circuit caused moist sounds.
Explanation:
The left ventricle receives oxygenated blood from the left atrium. Oxygenated blood from the lungs is carried to the left atrium by pulmonary veins. The left ventricle pumps the oxygenated blood to all body parts through the aorta. Failure of the left ventricle deprived the skin cells of oxygenated blood. Oxygen deficiency stopped energy production by cellular respiration. The result was pale and cold skin.
Failure of the left ventricle led to the accumulation of blood in the pulmonary circuit since the blood was not delivered to body tissues. The build-up of blood and resultant higher blood pressure caused moist sounds in the lower lungs.
The blockage of the coronary artery by a blood clot and death of a part of the heart due to lack of oxygen leads to a heart attack. The dead heart tissue is known as infarct and the resultant heart attack is myocardial infarction. Chest pain is caused due to the dead heart tissue or infarct.
About 0.3 percent is about the safe amount of water humans may consume, the other 99 percent is in oceans, soil, icecaps, and floating in the atmosphere.
Answer:
Explanation:
Gram-negative bacteria are more resistant to lysozyme and antibiotics than Gram-positive bacteria, because they have a largely thick impermeable cell wall (peptidoglycan), an outer lipid membrane that causes reaching of antibiotics to bacteria harder.
Gram positive bacteria have thin lipid peptidoglycan cell walls.
Typically, an organism has to have resources such as a food source, water source and some type of shelter in order to survive. For example, a bird needs to build a nest for a shelter, they have to have a water supply and a food supply of bugs or berries depending on the type of bird.
