Answer:
Rubella.
Explanation:
German measles is a viral infection that causes red rashes on the whole body of an infected person. The disease can be easily spread from infected people to healthy people by sneezing or coughing.
The German measles is caused by rubella virus.Rubella virus contains single stranded DNA as its genetic material. Rubella virus causes fever and swollen lymph nodes in infected individuals.
Thus, the correct answer is rubella virus.
 
        
             
        
        
        
Carbon dioxide is a byproduct of respiration while oxygen is a byproduct of photosynthesis.
Remember that a byproduct is a secondary product that is made in the synthesis of another. It is unintended and excreted.
        
             
        
        
        
A neuron is a specialized cell,  found in the brain, spinal cord and the peripheral nerves  known as the nerve cell. The structure of a neuron varies with their shape and size and it mainly depends upon their functions
<h3>what is the structure of neuron ?</h3>
Dendrites which is A branch-like structure that functions by receiving messages from other neurons and allow the transmission
Cell Body has a cell body with a nucleus, Golgi apparatus, endoplasmic reticulum, mitochondria and other components.
Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals 
Synapse  functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.

Five conditions<span> are required in order for a population to remain at </span>Hardy-Weinberg equilibrium<span>: A large breeding population. Random mating. No change in allelic frequency due to mutation.</span>
        
             
        
        
        
A protein domain is a conserved part of a given protein sequence and (tertiary) structure that can evolve, function, and exist independently of the rest of the protein chain. Each domain<span> forms a compact three-dimensional structure and often can be independently stable and folded.
On the other hand, a motif is a </span>distinctive sequence<span> on a protein or DNA, having a three-dimensional structure that allows binding interactions to occur. Early on, clustering was used to detect common three-dimensional structural motifs in </span>proteins<span>.
