The answer is a low-density particle
Producers: living things that make their own food through a process called photosynthesis
Autotrophs: an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Heterotrophs: an organism deriving its nutritional requirements from complex organic substances.
Photo autotrophs: organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration.
Stimulation of the sympathetic nervous system is required
Answer:
It equals the number of protons and electrons.
Explanation:
Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
