1) Diffusion and osmosis
the diffusion of water through a semipermeable membrane is osmosis and the movement of particles from regions of higher density to regions of lower density is diffusion
2)The passive transport does not require energy and the active transport does ,this is what makes them different
3)Endocytosis is a process for moving items that are outside of the cell into the cytoplasm of the cell. Exocytosis is a process for moving items from the cytoplasm of the cell to the outside.
Answer:
The correct answer is - option B.
Explanation:
The diversity of numbers of proteins in the human body is due to the differences in the structure of proteins. This change or difference in the structure of proteins is mainly affected by the sequence of amino acids.
The order of sequence of amino acid segment or residue in the peptide chain of the protein affects the structure of the particular protein which also leads to change in the secondary and tertiary structure of the protein.
Thus, the correct answer is - option B.
Answer:
1. interactions
2. environment
3. sun
4. photosynthesis
5. chemical
6. producers
7. food
8. energy
9. organisms
10. herbivores
10. first
12. Heterotrophs
13. second
Explanation:
An ecosystem consists of a community of living organisms
interacting with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.
Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
