Answer:
<h3>Maintenance of ionic balance.</h3>
Explanation:
Synovial fluid is a viscous fluid found in the cavity of synovial joints. In terms of appearance the synovial fluid appears  clear
, Colorless (pale yellow)
, viscous, microbes free.
Synovial fluid has following functions in our body 
a) shock absorption
b) nutrient distribution
c)  lubrication of the articular surfaces
d) waste disposal
 
        
             
        
        
        
Answer:
RFLP analysis of genomic DNA is facilitated by Southern blot analysis.   After electro-phoresis, DNA fragments in the gel are denatured by soaking in an alkali solution.  This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix).  A replica of the electrophoretic pattern of DNA fragments in the gel is made by transferring (blotting) them to a sheet of nitrocellulose or nylon membrane. This is done by placing the membrane on the gel after electro-phoresis and transferring DNA fragments to the membrane by capillary action or electro-transfer.  DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.

<span>Both the mushroom and the gecko are heterotrophs: they need to acquire their food from other sources. The tree, on the other hand, is an autotroph--it gains most of its nutritional needs through photosynthesis.</span>
        
                    
             
        
        
        
<span>The question is asking Which level of taxonomy has the fewest organisms?- therefore we have to choose the smallest group. This is the species, for example dogs are a species. then they form a genus together with Coyotes, and they they formgom with all other animals. Finally all eukaryotes are in the domain with dogs. So the smallest group is the species - only the dogs here in this example</span>
        
                    
             
        
        
        
Answer:
The correct option is DECREASED LEVELS OF CARBON DIOXIDE.
Explanation:
The major factors affecting photosynthesis rate are light intensity, carbon dioxide concentration and temperature. Increase or decrease in any of these three factors will directly affect the rate at which photosynthesis takes place. Increase concentration of carbon dioxide will generally increase photosynthesis while a decrease in its concentration will reduce the rate at which photosynthesis takes place.
