Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge. Viruses pose a challenge to the body's immune system because they hide inside cells.
Genetic translation occurs in ribosomes located in the cytoplasm of the cell.
<h3>What is Ribosome?</h3>
To execute biological protein synthesis, ribosomes, also known as Palade granules (after their discoverer George Palade and because of their granular structure), are macromolecular machinery that are present in all cells (mRNA translation). To create polypeptide chains, ribosomes combine amino acids in the order dictated by the codons of messenger RNA (mRNA) molecules.
The short and big ribosomal subunits are the two main parts of ribosomes. Each subunit is made up of numerous ribosomal proteins and one or more ribosomal RNA (rRNA) molecules (RPs or r-proteins). The translational apparatus also refers to the ribosomes and related components.

Answer:
d. different traits
Explanation:
Human cell are diploid (with the exception of gametes) which means that they have two sets of chromosomes: one inherited from mother and another inherited from father (23 chromosomes in each set, total of 46 chromosomes per cell). Those chromosomes in pair are called homologous chromosomes, they are the same in size and shape, contain the same genes but code for different traits.
Answer:Sunlight bounces off the surface of the lake. --Reflection
Sunlight shines on the beach and transfers heat to the sand. --Absorbtion
Waves of light are bent as they shine through the water to the lake bottom.--Refraction
Explanation: light occurs as beams which are made up of rays.
During reflection, light is re-emitted or through back from surfaces.it responsible for our ability to see things around us. Mirrors works on the principle of reflection
During refraction the direction of the wave changes as it travels from one medium to another of different optical density.in this case, light is passing from air to water,which are two media with different optical density.this change in media causes a bending of the light rays. This is the reason a stick placed a water may seem bent.
Sunlight carries heat .heat is a form of energy that moves as a result of temperature difference.heat from sunlight moves through the atmosphere without a material medium. Then it is absorbed by the particles of objects
