Soil and air because it is needed for the development of living beings
Answer:
nucleic acids.
Explanation:
The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.
Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.
• Biochemical processes give rise to the complexity of life
• Much of biochemistry deals with the structures and functions of biological macromolecules.
• Such as proteins nucleic acids, carbohydrates and lipids, which provide the structure of cells and perform many functions associated with life
Answer: "endodermis" .

Cells clump together during a process called agglutination as a result of the accumulation of antigens and antibodies.
Immune complexes are created when soluble antigens are brought together by the appropriate antibody molecules, and they become visible when they are big enough to precipitate out of the solution.
- The interaction between antibody molecules and the associated antigen molecules causes both agglutination and precipitation processes.
- Agglutination, on the other hand, is the clumping of cells that occurs when one antibody binds several antigens at once.
- Contrarily, precipitation occurs when soluble antigens and soluble antibodies interact to form a clear, insoluble substance known as the precipitate.
- Agglutination takes place when a target antigen, also known as isoagglutinin, interacts with a corresponding antibody in the presence of an electrolyte at the right temperature and pH, leading to the development of apparent clumps or aggregates.
- Precipitation happens when an electrolyte, an antigen, and a soluble antigen interact at the right temperature and pH to create cross-links or precipitates that sink to the bottom of the solution.
