Parenchymal cells, commonly found in plants, are best at storing food, especially in the form of starch. They hold numerous functions, including photosynthesis and repairing wounds. Other types of cells like sclerenchymal cells, cells in a flower petal, and prokaryotic cells either serve different functions or aren't typically found in plants.
The type of cell best at storing food for a plant would be parenchymal cells. These cells are the most common plant cells and are found in various parts of the plant, including the stem, root, the inside of a leaf, and the pulp of a fruit. Parenchymal cells are responsible for many metabolic functions like photosynthesis, aiding the repair and healing of wounds, and also play a particular role in the storage of starch, one of the main ways plants store energy.
Sclerenchymal cells, another type of cell mentioned, provide support to plants and are notably different as many of them are dead at maturity. While they contribute to the overall structure and stability of the plant, they do not store food. Cells in a flower petal also won't primarily serve as food storage units, and prokaryotic cells are typically found in organisms like bacteria, not plants.

Gas exchange in the respiratory system occurs in the alveoli, which are small air sacs located in the lungs. Oxygen diffuses from the alveoli to the capillaries, while carbon dioxide diffuses from the capillaries to the alveoli.
Gas exchange in the respiratory system takes place in the alveoli, which are small air sacs located at the ends of the respiratory bronchioles. These structures are found within the lungs. The alveoli are surrounded by capillaries, which are tiny blood vessels.
When we breathe in, oxygen from the air enters the alveoli and diffuses across the thin walls of the alveoli and capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be removed when we exhale.
So, the gas exchange occurs between the alveoli and the capillaries surrounding them.

The female should be gently wrapped with dry blankets due to exposure of temperature of about 25 degrees Fahrenheit.
Explanation:
Prolonged exposure to extreme heat or cold conditions can impair the body’s temperature control system.
In the above case the patient is exposed to extreme cold condition in a wood with a freezing temperature of 25 degrees Fahrenheit (-3 degrees Celsius) which leads to hypothermia and frostbite.
Extreme cold conditions can freeze the tissue layers of the parts of the skin exposed like those of the face, hands and feet especially. Due to this the skin becomes white (even grayish yellow or blue) and waxy, cold and numb, and the outer surface may become hard and blistered. There will also be extreme pain, stinging and tingling sensation in the exposed areas.
These changes are mainly due to impaired blood circulation and hypothermia. Hypothermia which is lowering of body temperature causes confusion and lethargy.
The first-aid given for frostbite primarily includes warming the body. The affected person’s body should be covered with warm and dry blankets gently and loosely and any wet clothes should be removed.
So when the body is warmed, the body temperature also will increase and correct the hypothermic symptoms like lethargy and confusion.
