Answer:
Biotic: Plants
Abotic: Rocks
Explanation:
A biotic factor is something in an ecosystem or environment that is living. Some examples that could be found in a park are grass, flowers, trees, squirrels, pigeons, fish or people.
An abiotic factor is the exact opposite of a biotic factor: something in an ecosystem or environment that is not alive. Some examples that may be found in a city park include a park bench, a trash can, rocks, a playground, a pool, basketball court, temperature, and humidity.
Answer:
An extraneous variable is eliminated, for example, if background noise that might reduce the audibility of speech is removed as Unknown extraneous variables can be controlled by randomization.
Answer:
This traumatic pathology occurs in children because the concentration of minerals is lower in children, since these have a greater collagen fibrillar organic structure, which is what gives children greater elasticity during bone growth until the areas close. proliferative.
The denomination in green stem comes from the analogy between this type of fracture and the one that occurs when trying to break the green stem of a plant.
It is characterized by being an incomplete fracture, with rupture of the periosteum and cortical bone on the convex side of the bone, while in the concave area the periosteum does not break, as a consequence the bone is not completely broken (incomplete fracture), but the fragments move and present an angulation of variable amplitude that needs to be corrected
Explanation:
To be more specific, these fractures occur more up to ten years of age, according to some research.
The centers of bone proliferation and differentiation where osteochondral mineralization of long bones occurs is what confers greater flexibility and greater organic content in the long bones of children.
