The answer is vascular plants.
Vascular plants have <span>specialized tissues that can transport fluids - vascular tissue. This tissue consists of</span><span> xylem and phloem. Xylem transports water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants. </span>
 
        
        
        
Answer:
A. glucose 
Explanation:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. 
 
        
             
        
        
        
Explanation:
Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is 
pH = -log[H+]. 
...where pH is -base 10 log of the concentration of hydrogen ions within the solution.
Initial volume= 20 mL
Final volume= 600 mL
# of dilutions=  = 30
 = 30
for a pH 2= [H+]= 
∴ [H+]=  
and pH is an antilog of [H+]= - log 
∴pH = 3.47

<span><span>Clouds of gas form within galaxies.
</span><span>Formation of structure within the gas clouds, due to "turbulence" and activity of new stars.
</span><span>Random turbulent processes lead to regions dense enough to collapse under their own weight, in spite of a hostile environment.
</span><span>As blob collapses, a disk forms, with growing "protostar" at the center.
</span><span>At the same time, bipolar outflows from forming star/disk system begin.
</span><span>Material is processed, moving in from the blob to the disk. What is not lost in the outflow builds up on the protostar.
</span><span>When the protostar begins to undergo fusion, it becomes a real star.
</span><span>Once the outflow ceases and the "accretion" phase that lead to the buildup of the star ends, a disk of "leftover" material is left around the star.
</span><span>At or near the end of the star-formation process, the remaining material in the "circumstellar disk" (a.k.a. "protoplanetary disk") forms a variety of planets.
</span><span>Eventually, all that is left behind is a new star, perhaps some planets, and a disk of left-over ground-up solids, visible as a "Debris Disk"around stars other than the Sun, and known as the "Zodaical Dust Disk" around the Sun.</span></span>
