Answer:
Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm
Function: metabolic functions are carried out in the bacterial cytoplasm
Replication: generally asexual (binary fission)
Explanation:
Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles
. Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, <em>Salmonella</em> is a genus of infectious bacteria that may cause an outbreak. <em>Salmonella</em> infection may be prevented by eliminating conditions where they can multiply. Measures to prevent <em>Salmonella</em> outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.
Mitosis, a procedure of cell duplication, or multiplication, amid which one cell offers ascend to two hereditarily indistinguishable girl cells. Carefully connected, the term mitosis is utilized to depict the duplication and dissemination of chromosomes, the structures that convey the hereditary data.
A concise treatment of mitosis pursues. For a full treatment, see development: In cells; cell: Mitosis and cytokinesis.
Preceding the beginning of mitosis, the chromosomes have imitated and the proteins that will frame the mitotic axle have been incorporated. Mitosis starts at prophase with the thickening and curling of the chromosomes. The nucleolus, an adjusted structure, shrivels and vanishes. The finish of prophase is set apart by the start of the association of a gathering of strands to frame a shaft and the breaking down of the atomic layer.
The chromosomes, every one of which is a twofold structure comprising of copy chromatids, line up along the midline of the cell at metaphase. In anaphase every chromatid pair isolates into two indistinguishable chromosomes that are destroyed to inverse closures of the cell by the shaft strands. Amid telophase, the chromosomes start to decondense, the axle separates, and the atomic films and nucleoli re-structure. The cytoplasm of the mother cell partitions to frame two girl cells, each containing indistinguishable number and sort of chromosomes from the mother cell. The stage, or stage, after the consummation of mitosis is called interphase.
P.S. You're a mean person. You ought to pursue different people groups bearing and don't simply answers something for focuses. Fortunately, I revealed you and your answers got delted and afterward erased the 50 points that you escaped your focuses. Try not to do that or else no one's going to like you. Bye....

Answer:
The sugar molecules in the marshmallow are being changed into carbon. Sugar can be changed into water molecules. When you toast marshmallows, the heat causes a chemical reaction producing water molecules which then evaporate, leaving the carbon behind.
Explanation:
They are descended from wild plants.
