The answer is B.
Animals do cellular respiration which requires the intake of oxygen and the output of carbon dioxide. In order for plants to do photosynthesis, they need carbon dioxide to be able to make oxygen for animals to breathe.
The first one. Gametes are the reproductive cells: sperm and egg cells. These contain the info that is passed on to the offspring, so an inherited mutation must be present in the gametes.
Answer:
Temperature will increase
Explanation:
As we know

Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.
As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.
The higher force leads to generation of higher pressure and hence the higher temperature.
All would be affected because decomposers like to break down dead things meaning dead plants AND animals
Not always, the toxins may have been absorbed by the body and released in urine
