Life is the period between the birth and the death of the organisms during which they perform various cellular activies and functions like growth, reproduction, digestion, excreation, etc.
Answer:
Photosynthesis
Photosynthesis. Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
The theory that is demonstrated by this experiment is natural selection.
Basically, only the strongest bacteria survived, and nature decided which of those bacteria were fit enough to get to live and reproduce in the future. Those bacteria that were "willing" and able to fight their way through a huge number of bacteria were the ones who ultimately won.
Answer:
As an embryo <u>develops</u>, identical cells give rise to specialized cells that <u>perform </u>different functions.
Explanation:
As an embryo develops, the cells divide, giving new ones. As the cells grow and continue to reproduce themselves, they differentiate, becoming specialized cells. These cells will be located in a particular part of the embryo and will perform a specific function. The shape, size, and organelles vary according to their role.
