The forelimbs of all mammals are homologous traits, meaning that they originate from a common ancestral trait.
The correct answer is therefore C. Homologies (homologous traits), from the same common ancestor. 
(To clarify, we know it is from a common ancestor because both bats and humans are mammals)
 
        
             
        
        
        
<span>For question 1: we know the vA=10.0 cm3 and the m=89.6g. Using the equation D = m/vA give us: D = 89.6/10 = 8.96 g/cm3. Answer is (C) 8.96 g / cm3.
For question 2: We know the vA=1.2 cm3 and the D=.6 g/cm3. Using the equation D = m/vA and rearranging for m gives us m = D*vA: m = .6 * 1.2 = .72 g. Answer is (D) .72 g.
For question 3: We know the D = 8 g/cm3 and the m = 600g. Using equation D = m/vA and rearranging for vA gives us vA = m / D: vA = 600 / 8 = 75 cm3. Answer is (A) 75 cm3.</span>
        
                    
             
        
        
        
Answer:
If the Earth suddenly had no gravity, the Earth’s atmosphere would float into space. Everything not attached to the Earth would fly off into space. Things like trees and most buildings would remain because they are rooted. Since the Earth, itself, is held together by gravity, it would most probably break apart into chunks and float off.
