Answer:
The correct answer is option C. They absorb water vapor from the atmosphere, providing water to the plant for photosynthesis.
Explanation:
Stomata are small opening present on the lower side of leaf. Its main function is to exchange of gases that are required for the process of photosynthesis. During day time, stomata are open and carbondioxode which is a raw material used for the production of glucose is absorbed from air and oxygen is released in the atmosphere.
The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.
Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed in isotonic plasma in which case water movement into the cell is equal to water movement out of the cell and so the cells remain intact.
Greenhouse gasses have increased due to carbon emissions and the amount of fossil fuels that humans are burning and releasing into the atmosphere. These gasses are keeping earths heat trapped, causing global warming/ climate change.
Answer:
The study of living things.
Explanation:
Biology is known as natural science which helps to study the life of living things along with some characters such as development in characters, evolution in species, chemical processes inside the body, physical body structure, and molecular interaction between the ions.
Living species such as animals, plants are known as an open system that has the ability to survive by lowering entropy and transforming the energy to sustain stable homeostasis. Biology helps us to identify the basic unit of life which is known as cell and for creation and extinction of living organisms.
