burn patients?
Answer:
Autografts are skin from the own patient, so the skin will not be recognized as a foreign substance, and there is no chance that the body will reject the cells.
Explanation:
These are the organic molecules:
1) Organic molecules can be found in living organisms, but they can also be found in non-living things, such as petroleum and coal.
2) The four major groups of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.
3) Carbohydrates are molecules that contain carbon, hydrogen, and oxygen. They are the most abundant biomolecules in living organisms. Carbohydrates can be simple sugars, such as glucose, or complex carbohydrates, such as starch and cellulose.
4) Lipids are a diverse group of molecules that are also made of carbon, hydrogen, and oxygen. Lipids are not soluble in water, but they are soluble in organic solvents, such as alcohol and ether. Lipids can be used for energy storage, insulation, and protection.
5) Proteins are molecules that contain carbon, hydrogen, oxygen, and nitrogen. They are essential for life and are involved in a wide variety of functions, such as structure, metabolism, and cell signaling.
6) Proteins are composed of amino acids. Amino acids are molecules that contain an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R). The side chain varies from amino acid to amino acid and gives each amino acid its unique properties.
7) Linked amino acids form polypeptides. Polypeptides are chains of amino acids that are linked together by peptide bonds.
8) The two forms of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
9) Nucleic acids are composed of nucleotides. Nucleotides are molecules that contain a sugar, a phosphate group, and a nitrogenous base. The sugar in DNA is deoxyribose, while the sugar in RNA is ribose. The nitrogenous bases in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). The nitrogenous bases in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U).
10) Nucleotides link together to make a nucleic acid through phosphodiester bonds. Phosphodiester bonds are formed between the phosphate group of one nucleotide and the sugar of the next nucleotide.
11) DNA and RNA are structurally different in several ways. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous bases adenine (A), guanine (G), cytosine (C), and thymine (T), while RNA contains the nitrogenous bases adenine (A), guanine (G), cytosine (C), and uracil (U).

Answer:
how do i actually answer you bro? there are so many questions
The difficulties that a cell faces as it increases in size are a reflection of the fact that cells are complex systems.
As a cell increases in size, it faces a number of difficulties. These include:
Diffusion: As a cell gets larger, the distance between the cell membrane and the center of the cell increases. This makes it more difficult for nutrients and oxygen to diffuse into the cell, and for waste products to diffuse out of the cell.
Surface area to volume ratio: The surface area to volume ratio is a measure of how much surface area a cell has relative to its volume. As a cell gets larger, its surface area to volume ratio decreases.
This means that the cell has less surface area to exchange nutrients, oxygen, and waste products with its environment.
Cytoskeleton: The cytoskeleton is a network of fibers that provides support and structure for the cell. As a cell gets larger, the cytoskeleton must become more complex and stronger in order to support the increased weight and volume of the cell.
Organelle function: As a cell gets larger, its organelles must also become larger and more numerous in order to meet the increased metabolic demands of the cell. However, there is a limit to how large and numerous organelles can become before they become inefficient or even dysfunctional.
For all of these reasons, there is a limit to how large a cell can grow. Once a cell reaches a certain size, it becomes more efficient for it to divide into two smaller cells.
This allows the new cells to have a more favorable surface area to volume ratio and to have more efficient access to nutrients and oxygen.

The sentence that use the word biome is, "Rainforests are the oldest living biomes on Earth."
Various continents may have different biomes. The word "biome" encompasses a wider range of environments than "habitat."
Any place is categorized as a biome based on the species that call it home. Scientists may define a biome by defining the temperature range, soil type, quantity of light, and water that are peculiar to a location and create niches for particular species.
There are many kinds of biomes, such as deserts, tundra, grasslands, coniferous woods, and temperate deciduous forests.
