Answer:
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
Explanation:
When soil has high salt concentration, it becomes very difficult for the plant to take in water. Sometimes the problem becomes so peculiar that plant becomes completely unable to take in the water and hence they wilt and die. This happens even when the surrounding soil has sufficient water but remains un-drawn by the plants due to its high osmotic potential resulting due to highly concentrated salt solution. Therefore, more energy and effort is required by roots to extract water from salty sand.
Also if the salt concentration with in the plant increases, it remains there and causes damage
Hence, correct options are
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
Answer:
Hepatitis A
Explanation
Hepatitis A is caused by is caused by Hepatitis A virus which infects the liver and causes an inflammation.
The virus for Hepatitis A is spread through eating or drinking something contaminated with fecal matter and it is highly contagious.
However, it is preventable by vaccination.
Since it is a food borne disease which is highly contagious, a food handler has to be excluded from operation and a medical practitioner has to determine when the person can resume to avoid further transmission.
Answer:
The air pressure at Mt. Everest is much less than the air pressure at sea level because air pressure decreases with altitude. This is because at higher altitudes, there is less air pushing down from above. An addition, gravity is weaker, as it is farther from Earth's center. Because of this, air molecules can spread out more at higher altitudes, resulting in decreasing air density.
