The thing that is happening when you gargle with salt water is you are creating a high-salt barrier. As a result fluids are pulled out from the tissues in the throat area and the viruses are washed out. Fluids (water) are moving down the concentration gradient (to the area with the high salt concentration) and this is an example of passive transport.
Paramecium is protozoan which is like a bedroom slipper in shape and swims rapidly in a corkscrew fashion by means of an army of cilia that operate in wavelike movements. These tiny creatures are abundant in freshwater ponds, especially in areas that are rich in algae.
Paramecium rescued from a fresh pond in Florida is among the most complex single-celled organisms found in fresh water. The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be longer and would be more saturated compared to those in the membranes of the Canada Paramecia.
Moreover, the species Paramecium bursarial shapes advantageous associations with green growth. The green growth lives in its cytoplasm. Algal photosynthesis gives a nourishment source to Paramecium. Paramecia can be utilized as model creatures to examine. You should know that the paramecium swims by rotating along its longer axis and is constantly in search of food, which is swept into the organism by a series of cilia that line the oral groove and gullet.<span>

A plant cell has chloroplasts.
An animal cells doesn't.
Answer:
Epidermis layer of the skin will be most affected and blisters indicates that dermis layer of skin has also been affected.
Explanation:
The sunlight contain ultraviolet radiations which can damage the skin. The UV radiations causes serious damages to DNA and other parts of the cells directly and also by the production of free radicals. These radiations damage the DNA and cell tries to rectify them. These damages to DNA causes problems in cell replication through errors in DNA replication. If the damage is too frequent that cell can't repair it the immune response will destroy the cell.
Epidermis is the outermost layer of skin which protect the internal cells from external damages and dermis is present beneath the epidermis and it provides nutrient rich blood to epidermis. If the UV radiations are too intense they can penetrate more deeper and can damage the dermis also.
Skin burn can occur in less than 15 minutes depending upon the intensity of UV radiation. The skin become red and blisters appeared on skin. More chronic skin burn can also cause fever, chills and even death.
