10. 8t^9(.16r^2) = 1.28t^9*r^2
Literally just learn how things operate and break them down its not hard. Learn the properties, you will need simple problem solving skills for life.
Answer:
One species would better adapt to fill that niche, and the other species would be forced to leave the ecosystem or die.
Explanation: I promise its right
It helps by making sure you stay warm and not freeze to death
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.
Anaerobic breakdown of glucose produces lactic acid, which accumulates in the tissues and blood.
