Answer:
Active transport; Passive transport; Passive transport
Explanation:
When concentration of a substance is different on either side of a semi-permeable membrane, the movement of this substance can occur by active or passive transport. Active transport occurs when the substance is moved from the region of its lower concentration to that of its higher concentration. This type of movement uses the energy to move the substance. Since the glucose concentration is higher in the epithelial cells than in the food, it will enter into the cells by the process of active transport.
The passive movement of substances is driven by concentration gradient. The glucose concentration is lower in extracellular space than epithelial cells, so glucose will be transported into the extracellular space by passive movement.
Likewise, a higher concentration of glucose in extracellular space than blood will move it passively into the bloodstream.
Answer:
Recent studies suggest that noise pollution can harm whales directly by damaging their hearing, and in extreme cases, causing internal bleeding and death. More commonly, it appears that excessive or prolonged noise can cause behavioral changes that interfere with the health and survival of the animals.
Explanation:
Alcohol has immediate short term effects on one's body which includes the brain,pancreas,heart and gut yet the most immediate effect is on the brain. The effects of alcohol on one's brain is usually felt within 5 minutes of the alcohol once swallowed. It usually blocks or slows down the function of the brain causing the drinker to be excited or be relaxed. Some of the effects include loss of balance,drowsiness,slurred speech and nausea and vomiting.
