I believe that David's prediction would be: If the amount of pollutants in the atmosphere reached an amount unhealthy for the salamanders, then the salamander population would decrease.
Let me know if this helps :)
 
        
             
        
        
        
A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is <u>genetically identical</u> to the parent.
Answer: Option C
<u>Explanation:</u>
Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.
whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.

Archaebacteria have cell wall made of complex composition of peptidoglycan
 
        
             
        
        
        
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
        
             
        
        
        
It is b) angle B.
The opposite angles of opposite sides are proportional to each other. So the smallest side’s opposite angle will be the smallest angle, and in this case, since the largest side is 12, the opposite angle, B, will be the largest angle.
Also, make sure to check to see if the question is the right subject, hope this helps
