Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.

Answer:
According to researchers, several factors have led to an increase in the human population since the last 200 years.
The main reason for the growth in the human population is the decrease in the rate of deaths as compared to the rate of births. With the developments in science and particularly health sciences, the death rate by infections or diseases has been reduced to minimal. Even efforts are being made to increase the life span of a human being by scientists.
On the other hands, the birth rates are increasing day by day. The population is increasing mainly in third world countries where people do not take care of birth controls.
