Answer:
In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>
Explanation:
The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.
Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.
 
        
                    
             
        
        
        
The answer is ATP production glycolysis, Krebs cycle, and electron transport aerobic in that order. Glycolysis occurs in the cytoplasm while the other two stages occur in the mitochondria (Krebs cycle in the mitochondrial matrix and the electron transport chain in the mitochondria membrane). 
The answer is Autotrophs. Examples of autotrophs are plants and photosynthetic bacteria (photoautotrophs). They convert abiotic factors such as light to organic molecules. These also include chemosynthetic bacteria (chemoautotrophs) that elements such as sulfur dioxide and methane in hydrothermal vents to organic molecules.

Answer:
template 5'->3"
Explanation:
As we all know, with a linear chromosome, on the lagging strand (template 5'->3') of DNA replication, when the last piece of RNA primer at the 3' end is removed, the DNA cannot be extended and this creates the end replication problem.
