Answer:
B)  The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products. 
We know this by virtue of the law of conservation of mass. 
  The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged". 
  Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction. 
The second choice is the right one. 
 
        
             
        
        
        
Answer:
3/8
Explanation:
Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).
Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).
This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes
So, martha's alleles are: Ww and ee.
If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are
Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee
 
        
             
        
        
        
<h2>Cellular respiration </h2>
Explanation:
- Cellular respiration is defined as a ATP generating process in which organic molecule is oxidized and inorganic molecule is final electron acceptor
- Pain experienced in leg muscles is the result of formation of lactic acid in muscle cells
- Under low oxygen, NADH cannot be reoxidized to NAD+ but NAD+ is required as an electron acceptor to continue glycolysis 
- In lactic acid fermentation pyruvate is the final electron acceptor and converted in lactate 
- Reaction catalyzed by lactate dehydrogenase 
- The pain in her chest is caused from the lack of oxygen she received while running so her chest starts to heavily breathe so that the lungs can receive as much oxygen possible 
 
        
        
        
Oxidized hydrogen does not participate in mineral formation.
        
             
        
        
        
Answer:
Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing "large" objects that are visible to the naked eye at low magnifications (under 50x). A stereo microscope provides an upright and unreversed, 3-dimensional image of the specimen.
