Answer:
Option A) is correct.
Explanation:
 Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.
Electromagnetic waves do not require a medium to travel through space without a medium. Electromagnetic waves can travel through air,  vacuum of space and solid materials.
So,
Option A) is correct.
 
        
             
        
        
        
Options are not provided in the question. I found the answer on the Internet. 
Yes, deletion of the possible control elements can cause reduction in reporter gene expression. Due to deletion of a control element, the activator cannot bind to the enhancer. This causes reduction in the gene expression. 
Answer: Deletion of element no. 3 causes a reduction in reporter gene expression.  
        
             
        
        
        
Answer;
Kingdom, Division, Class, Order, Family, Genus and Species
Explanation; 
-The plant kingdom is divided into three divisions namely Bryophyta, Pteridophyta and Spermatphyta.
-Division Bryophyta includes mosses and liverworts. Division Pteridophyta includes the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.
-Division Spermatophyta comprises all the seed bearing plants. They are familiar green plants which produce seeds through flowers or cones. The division spermatophyte consists of two main subdivisions: Gymnospermatophyta and Angiospermatophyta, which are the divided into classes and so forth,.
 
        
             
        
        
        
The surface area of a sphere can be approximated as follows: Surface area = 4πr2; where r is the radius of the sphere; π is a constant that is roughly equal to 3.
        
             
        
        
        
Movement and balance are monitored by activity in the cerebellum.
<h3>What is meant by the cerebellum?</h3>
The cerebellum, also known as the "little brain" because it resembles a miniature cerebrum, is in charge of balance, movement, and coordination. The pons and medulla, along with the midbrain, are commonly referred to as the brainstem. The brainstem receives, sends, and coordinates messages from the brain.
The cerebellum is the area of the brain in charge of coordinating voluntary movements. It is also in charge of a variety of functions, including motor skills like balance, coordination, and posture.
The cerebellum is important for maintaining balance by making postural adjustments. It modulates commands to motor neurons based on input from vestibular receptors and proprioceptors to compensate for changes in body position or muscle load.
Therefore, the correct answer is option B) cerebellum.
