Answer:
The different levels of biology are described below.
Explanation:
Biology can be studied at different levels from a single cell to the entire biosphere. The ladder from a single cell to the biosphere is known as the biological level of organization.
Following are the levels of organization:
A cell comprises of different organelles and is the main unit of life. For e.g bone cells
Tissues:
The cells combine to make tissues. For e.g the connective tissue
Organs:
Different tissue work together to make an organ. For e.g stomach
Organ system :
Different organs work together to make an organ system. For e.g The circulatory system contains heart and the blood vessels.
Organism:
Organ systems combine to make an organism. for e.g any human
Population
Group of organisms of the same species. For e.g a group of humans
Community
The different populations present in an area. For e.g all the plants, animals and microbes in an area.
Ecosystem
All the biotic as well as abiotic factors in an area make the ecosystem.
Biome
Different communities that can exist in the same climate.
Biosphere
Biosphere is all the life that exists on the planet earth and also all the abiotic factors present on earth.
Answer: The answer is A
Explanation: Research and Edu labs
The solute is the substance dissolved in water.
A hypotonic solution is a solution with a low concentration of solute.
A hypertonic solution is a solution with a high concentration of solute.
An isotonic solution is a solution that contains equal concentrations of solutes.
The direction of water displacement (or osmosis) depends on the total concentration of solute on each side of the membrane and not the nature of the solute.
The correct way to describe science is that is referred as a way of knowing.
The reason for this definition is that, it is responsibility of ancient to help humans to gain knowledge and understands in response to what they want to search so as to know more about something.
It organizes and builds knowledge for predictions and explanation on the universe.
Science can be divided into natural science, social science which include economics, and formal science which include mathematics.
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
