Answer:Both birth rate and death rate will decrease.
Explanation:
Demographic transition: The process whereby a country moves from high birth and death rates to relatively low birth and death rates.
The decline in death rate is due to better economic and social conditions of the country which leads to control of pre-existing diseases, better medical facilities,more food production,increased jobs,better sanitation and hence better quality of life.
Decline in birth rate is due to improved quality of life and also could be due to availability of family planning services in highly developed countries.Moreover access to education especially in female population has created awareness regarding birth control.

Answer:
No cellular energy is needed in the Passive transport.
Explanation:
A movement of atomic molecules and ions throughout the cell membrane is known as passive transport. In this transportation of molecules no cellular energy is used.
As this movement is influenced by the tendency to grow as entropy, the energy is not in need unlike the active transport. Its rate depends on the permeability of cell membrane. There are four types of passive transport- facilitated diffusion, simple diffusion osmosis or filtration.
Answer:
B.
Explanation:
Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.
ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.
Hence, the correct option is "B".
