The rigth answer is D.
The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).
 
        
                    
             
        
        
        
one gamete from each locus (position of chromosomes). The parent with genotype will produce the gametes as: The heterozygous diploid pair of gives two different gametes, say and . Similarly the heterozygous diploid pair of , gives and .
 
        
             
        
        
        
Answer:
<em>S. aureus</em> is spherical and arranged in clusters
Explanation:
<em>Staphylococcus aureus </em>is a gram positive bacteria that forms a part of our body microbiota. It is usually found on skin and in upper respiratory tract. The genus name of this organism is <em>Staphylococcus </em>which tells a lot about its morphology. Cocci or coccus is the name given to bacteria who appear spherical. Staph points out to their arrangement which is in clusters. Had it been <em>Streptococcus</em>, it would mean that the bacteria were spherical and arranged in long chains. Similarly, <em>Diplococcus</em> would mean that the bacteria were spherical and arranged in groups of two. Hence from the name <em>Staphylococcus aureus </em> we can say that it is spherical and arranged in clusters.
