1 kilometer = 6.68 × 
(<<<AU is in scientific notation here)
To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × )
3,000,000,000 × (6.68 × ) = 20.04 AU
Hope this helped!
Correct answer: A). Move away from one another
The divergent boundaries are formed when the tectonic plate move away from each other. It forms volcanic islands that occur when the plates move away in order to produce gaps that are filled by molten lava.
The divergent boundary contributes to the formation of seafloor spreading. When the plates that are made up of oceanic crust move away from each other, a crack in the ocean floor appears. Then the magma oozes out from the mantle to fill that crack that results in ocean ridges.
Hence, the correct answer would be option A.
Answer:
Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.
Explanation:
Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.
Answer:
The rocks may have different textures
Explanation:
If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.
