"Rainwater can replace or replenish freshwater sources" and "precipitation, such as rainwater, is a source of freshwater on Earth" statements describe freshwater sources
<u>Explanation:</u>
Rainwater a source of pure distilled water, evaporated by the sun. When it falls it comes in contact of air and land. when ground soaks the water it becomes mineral water. And it is safe for drinking.
All the freshwater sources are result of precipitation from the earth surface,in various form i.e rain,mist,snow. Freshwater falling as rain have materials dissolved from atmosphere in it,sea and the land over which the clouds has travelled.
Gas exchange occurs in the alveoli of the lungs and each is made from a single layer of flat cells, Many alveoli in the lungs, so a large surface area for exchangement of C02 and O2. They are surrounded by a network of capillaries and oxygen diffuses out of them via the alveolar epithelium to the hemoglobin.

Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.
the student should scrap off the layers until a very thin layer remains and put it back on the microscope then the student will be able to view the details of only one cell layer
