Answer:
The burning of wood and the burning of food calories produce carbon dioxide and heat. The calory burning gives energy to the body but in wood burning only wood becomes a carbon compound i.e. ash.
Explanation:
The burning of wood and the burning of calories release carbon dioxide and heat. In the body, oxygen breaks down the food calories and produces CO2 which release from the body by exhalation. The heat produced by food burning causes sweating. Oxygen also helps in burning of wood. In this way the food calory burning and wood burning are similar.
In calory burning the complex food becomes simpler and helps in tissue metabolism. In wood burning atmospheric oxygen helps in burning, and they release other gases like carbon monoxide, nitrogen to the environment which is not happening in case of metabolism. The complete burning of wood results in carbon compounds. In calories burning excess energy is stored in the form of fat. Because food calories are nothing but energy derive from different food.
B. using solar cells
C. using windmills
D. using nuclear fission
Answer:
A. burning fossil fuels
Explanation:
Acid rain is caused, mainly by the emission of sulfur oxides and nitrogen oxides, which are gases commonly released into the atmosphere as a result of burning fossil fuels.
These oxides have the ability to interact with rainwater generating an acidic substance that is expelled from the clouds in the form of rain that has a very acidic pH.
The result of acid rain is the destruction of vegetables, the chemical alteration of water bodies, the death of aquatic animals, the contamination of groundwater and even the emergence of respiratory diseases and the destruction of public heritage.
Answer:
Cellular respiration is a cellular process by which the organism in the presence of oxygen breakdown glucose and release energy that is stored in the form of ATP.
The by product of this process is carbon dioxide and water. This carbon dioxide is used by plants for the process of photosynthesis.
This is one of way by which carbon dioxide is provided to relay the carbon cycle.
Gametes, or sex cells, are located in different parts of the body based on the individual's sex. In males, they are found in the testes, and in females, they are found in the ovaries. In plants, they are found within the reproductive structures.
Gametes are the sex cells that are located in different parts of the body depending on the sex of the individual. In males, sperm, which are the male gametes, are produced and stored in the testes. In females, eggs, or ovum, which are the female gametes, are produced in the ovaries. In terms of plants, gametes are found in the reproductive structures, such as flowers and cones. For instance, in flowering plants, the male gametes are located within the pollen grains produced by the anthers, and the female gametes are located within the ovule in the ovary of the flower.

Answer:
A. an increase in skin cancer among humans
Explanation:
The ozone layer is a part of the stratosphere that absorbs most of the Sun's ultraviolet(UV) radiation.The ozone layer contains a lot of ozone present in it and it serves as a shield. The radiations are harmful to the body and pose serious health risk when humans are exposed to them.
Such risks include cancer of the skin due to the skin being the part of the body at a greater risk of exposure.
