Answer:
Which substance has a high albedo? B) White Sand
Explanation:
The albedo is the amount of energy that is reflected by a surface. It is determined by the refletivity of that surface. Albedo can range from 0 (no reflection) to a value of 1 (100% reflection). Generally, dark surfaces have a low albedo and light surfaces have a high albedo. Liquid water is considered to have a low albedo, like dark rock and rich soil.
Answer: False
Explanation:
Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.
The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.
The mode of transmission can be vector that carries disease and helps in disease transmission.
So, the pathogens can be transmitted by direct contact, indirect contact or by vectors and by many more ways.
Answer:
Plasmolysis
Explanation:
In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.
The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.
The image 2 plant cell is exposed to a solution which is high concentrated solution.
Due to this high concentrated solution the water present in the cell is send out by exosmosis.
Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.
This shrinkage of protoplasm by loss of water is called plasmolysis.
