Carbohydrate are compounds of carbon, hydrogen and oxygen in which the ratio of hydrogen atoms to oxygen atoms is 2:1. A certain carbohydrate is known to be 40% carbon.
Water vapour and gases such as oxygen and carbon dioxide are able to move across the egg shell through small openings called pores. The egg contains all the nutrients that the developing chick needs during the three weeks of incubation period.
Answer:
Photosynthesis, respiration, diffusion, osmosis
Explanation:
Homeostasis refers to the ability of an organism to maintain a stable internal state despite changes in external environment. In order to perform this process, some processes are required to be performed by the cell including:
- Photosynthesis, which is the process by which plants synthesize their food, helps the plant supply energy needed by the cell to perform it's function.
- Cellular respiration is the process of synthesizing energy (ATP) by the cell. Energy is needed by the cell for the numerous functions it carries out. Hence, cellular respiration is a homeostatic process.
- Diffusion is the process by which substance move from a region of high conc. to a region of low conc. until there is even distribution. Without diffusion, some materials cannot get into the cell, hence, it is a homeostatic process.
- Osmosis is the movement of water from a region with high water conc. to a region of low water conc. via a permeable membrane. The osmotic process is also a homeostatic one.
