Answer:
Oxygen is used to break down sugar and sugars release energy
Fixation
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria
Answer/Explanation:
Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.
Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.
On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.
A fracture or dislocation is a break or crack in the bone. It is when two bones are out of place at the joint that connects them which may also cause injury to nerves and blood vessels. The types of fracture are: Closed refers to fracture that does not break skin, Open, a fracture where external wound associated with fracture, Non displaced, a simple crack of bone and the Displaced, a fracture in which there is actual deformity. But there are three types of treatment for fracture or dislocation namely: Open treatment, examples are Surgically Cleaning the Bone, Removing Contaminated or Non-Viable Tissue, Stabilizing the Bone and many more. Other type of treatment is closed treatment like No immobilization and Cast Immobilization. Third type of treatment is Percutaneous Skeletal Fixation like internal and external fixation.
In terms of cell division, normal cells differ from cancer cells in at least four ways. Normal cells require external growth factors to divide. When synthesis of these growth factors is inhibited by normal cell regulation, the cells stop dividing.
