It's B
Explanation:
Because the fossil record shows how organisms have evoluate from relatively simple organisms to more complex organisms
 
        
                    
             
        
        
        
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Answer:
A
Explanation:
The reaction used in the brewing industry is realized by a fungus called Saccharomyces Cerevisae which converts glucose into ethanol and carbon dioxide. Glucose is first transformed into pyruvate.
The second reaction is the reaction for lactic fermentation made by bacteria like Streptococcus lactis or Lactobacillus bulgaricus
The third reaction is the reaction of aerobic respiration
 
        
             
        
        
        
The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.
Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.
Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment. 
Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

Answer: A
Explanation: The nervous system sends electric signals from the brain to the body to make they move. The charger is similar becuase it sends energy to your devices so they can work.
