Answer:
On the Gizmo it only shows one DNA fingerprint scan, meaning that it scans only one out of the four nitrogenous bases. Therefore, it is not entirely accurate, resulting certain frogs not being entirely identical twins.
Explanation:
That good?
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.
If the marine plant is placed in a freshwater environment, then the cells will undergo plasmolysis.
The plants found in the freshwater surroundings are adjusted for osmoregulation in hypotonic environments. If one place this type of plant in a marine environment, that is, one with a greater concentration of dissolved salts, then the environment is considered as hypertonic environment. The cells of the plant will lose water and will go through the process of plasmolysis.
Anna's infection affected her body cells, it impaired the body's function and all organs. The urinary tract infection resulted to a septic shock that caused multiple organ failures. In addition to this, bacteria is yet to be identified so there is no actual reason stated for the cause of death.
Answer:
Nitrogen is converted from atmospheric nitrogen into forms, such as NO2-, in a process called fixation. The majority of nitrogen is fixed by bacteria, a lot of which are symbiotic with plants.
Answer: Fixation
