<span>In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, and
protein combine to form a nucleoprotein called a ribosome. The ribosome
serves as the site and carries the enzymes necessary for protein
synthesis. They are often takes the shape of small round particles
attached in the endoplasmic reticulum. The ribosome attaches itself to m-RNA
and provides the stabilizing structure to hold all substances in position as
the protein is synthesized. Several ribosomes may be attached to a single RNA
at any time. <span> </span></span>
A reaction is first order. If the initial reactant concentration is 0.0200 M, and 25.0 days later the concentration is 6.25 x 10-4 M, then its half-life is:
A mixture consists of two or more components. a solution can consists of a solute dissolved in a solvent or two solvents mixed together, for instance. A mixture can also be two gases (CO2 and O2) mixed together or two solids mixed together (sawdust and chalk).
Answer: None of the above statements is false.
Explanation:
In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.
In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.
In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.
Thus, we can conclude that none of the given statements are false.
