Answer:

Explanation:
To find the weight (W) of the pond contents first we need to use the following equation:
   (1)
Where m the mass and g is the gravity  
Also, we have that the mass is:
  (2)     
Where ρ is the density and V the volume
We cand calculate the volume as follows: 
   (3)
Where L is the length, w is the wide and d is the depth  
By entering equation (2) and (3) into (1) we have:

   
              
Therefore, the weight of the pond is 6.65x10⁶ lbf.
I hope it helps you!
 
        
             
        
        
        
Answer:
D) One half of the carbon atoms of newly synthesized acetyl CoA. 
Explanation:
It will be radioactively labeled because Malonyl CoA which contains 3 Carbon molecule is synthesized from Acetyl CoA which has 2 Carbon molecule. 
This happens with the addition of ‘CO2’ with the help of the enzyme called acetyl CoA carboxylase.
 
        
             
        
        
        
Answer:
Gelada baboons plays a significant role.
Explanation:
The role of gelada baboons in their ecosystem is very important because they aerate the soil for plants which is necessary for good plant growth. These gelada baboons also helps in controlling the population of predator in their ecosystem which is very essential for the stability and equilibrium of the ecosystem so gelada baboons has a good effect on both plants and animals in their ecosystem.
