| Question | Answer |
| Muskuloskeletan system | is a human body system that provides our body with movement, stability, shape, and support. |
| Types of muscles | 1.Cardiac muscle 2.Smooth muscle 3.Skeletal muscle |
| Cardiac muscle | which forms the muscular layer of the heart |
| Smooth muscle | which comprises the walls of blood vessels and hollow organs |
| Skeletal muscle | which attaches to the bones and provides voluntary movement. |
| Tendons | is a tough, flexible band of dense connective tissue that serves to attach skeletal muscles to bones. |
| Joint | Is the part of the body where two or more bones meet to allow movement. |
| Cartilage | is a flexible connective tissue that keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact. |
| Bones | are rigid structures made of calcified dense connective tissue. Bone tissue is composed of a mineralized bone matrix that consists of type 1 collagen fibers dispersed throughout the ground substance. |
| Ligaments | are fibrous bands made of dense regular connective tissue which are similar in structure to tendons. Unlike the tendons that connect muscles to bone, the ligaments connect bone to bone. |
| Biogeochemical cycles | he ways in which an elemen or compound moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles. |
| Water cycle | Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation). |
| Carbon cycle | describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Humans play a major role in the carbon cycle through activities such as the burning of fossil fuels or land development |
| Sulfur cycle | is biogeochemical cycle in which the sulfur moves between rocks, waterways and living systems. ... Steps of the sulfur cycle are: Mineralization of organic sulfur into inorganic forms, such as hydrogen sulfide (H2S), elemental sulfur, as well as sulfide minerals. |
| Hydrogen cycle | the transmission of hydrogen from water to carbohydrates etc and back to water by living organisms. hydrogen cyclenoun. the electrolysis or solar photolysis of water to give hydrogen and oxygen which are then recombined in a fuel cell to produce electricity. |
| Phosphorus cycle | is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Low concentration of phosphorus in soils reduces plant growth and slows soil microbial growth, as shown in studies of soil microbial biomass. |
| Nitrogen cycle | it is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates between the biosphere, terrestrial and marine ecosystems. Nitrogen conversion can be carried out both by biological and physical means. |
| Magnet | It is an object that is able both to attract iron and steel objects and also push them away |
| Properties | MAGNETIC FORCE MAGNETIC POLE MAGNETIC FIELD |
| Tipes of Magnets | Ferromgnets Electromagnets Temporary magnets |
| Magnetism | It is the set of physical phenomena mediated by magnetic fields. These can be generated by electrical currents or by the magnetic moments of the constituent particles of the materials. It is part of a more general phenomenon: electromagnetism. |
