Answer:
The bones of a synovial joint are surrounded by a synovial capsule, which secretes synovial fluid to lubricate and nourish the joint while acting as a shock absorber. The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement.

Answer:
The function of organelles is to provide a specific function for the cell.
Explanation:
Eukaryotes have organelles not prokaryotes. All the cellular processes of prokaryotes occur in one cell. The advantage of having seperate spaces to do various functions is for regulation and maintance.
The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".
Answer:
land use
Explanation:
Runoff of water is said to occur when the water portion of an area flows as surface water rather than being absorbed into the ground or evaporated into the atmosphere. The amount of runoff that occurs in a particular area is influenced by certain factors including land use, amount of vegetation, slope of land, soil type etc.
The way a portion of land is used, the structures built on it can increase the amount of runoff on that land. A natural, unexploited land will be less affected by runoff because water has a higher chance of infiltrating the soil.
