Ventilation is the process which the air moves in and out of the lungs. Diffusion is the movement of gases without the use of energy and or effort by the body. Hope this helps!:)
        
             
        
        
        
Answer:
The correct answer is option c. Haploid spores.
Explanation:
In the plants, spores are normally unicellular and haploid and produced by the process of meiosis in the sporophytic body of the plant.
These haploid spores undergo the mitotic division and develop a new individual called gametophyte that forms gametes eventually.
Thus, the correct answer is option C. Haploid spores.
 
        
             
        
        
        
The condensation of water vapor formed the early oceans. It is an important part of the water cycle. It is easy to eliminate the other answers in this question. It can't be meteorites, living organisms, or nitrogen.
        
                    
             
        
        
        
The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated. Their main role is the separation of double-stranded DNA into single strands allowing each strand to be copied during the process of replication. It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />
        
             
        
        
        
Answer: and Explanation:
A.)The reason for the different products of glycogen breakdown in the two tissues is that glucose 6-phosphotase which is 
a known enzyme that brings about hydrolysis of glucose 6-phosphate as a result of the creation of a phosphate group and free glucose is not available in heart and skeletal muscle, therefore,any glucose 6-phosphotase that is produced will just enters the glycolytic pathway and get converted to lactate through pyruvate, in the absence of Oxygen O2.
B) Whenever a situation involving fight or flight arises, the concentration of glycolytic precursors becomes high in order to prepare for muscular activity. Since the membrane is impermeable to any charged species, and at the same time glucose 6-phosphotase enzyme cannot be moved through the glucose transporter, then there cannot be a release of Phosphorylated intermediates from the cell. The blood glucose level must be maintained by the liver by releasing of glucose.
glucose that is later formed from glucose 6-phosphotase then enters the bloodstream.
