Solar System[a] is the gravitationallybound system of the Sun and the objects that orbit it, either directly or indirectly,[b] including the eight planets and five dwarf planets as defined by the International Astronomical Union (IAU). Of the objects that orbit the Sun directly, the largest eight are the planets,[c]with the remainder being smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the moons—two are larger than the smallest planet, Mercury.[d]

The Solar System formed 4.6 billion years agofrom the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiterand Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All eight planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.
Amino acids are essentially the "building blocks" of proteins. You could think of it as an individual amino acid combining with others to form a link or stand.
<span>Essential part of the maculae involved in static equilibrium is otoliths. The otolith organs sense gravity and linear acceleration such as from due to initiation of movement in a straight line. Persons or animals without otolith organs are imbalanced. The otolithic organs sense motion according to their orientation.</span>
Answer:
a. add more of the enzyme
Explanation:
Enzymes have specific sites to which their substrates bind during the reaction. These sites are called active sites. When all the active sites of all the enzyme molecules present in a solution are bound to the substrate molecules, the enzyme is said to be saturated with the substrate. Under these conditions, more enzyme molecules are to be added to the solution to increase the reaction rate and to obtain the product at a fast rate. The addition of more enzymes will allow more substrate molecules to occupy the active sites and to be converted into the product/s.
It is a fact that nuclear energy is converted into thermal energy in the core of a nuclear reactor. This is because it is part of a power plant fission act, where nuclear energy heats up water in a nearby vicinity.
