The overall mechanism of cellular respiration<span> involves four subdivisions: glycolysis, in which glucose molecules are broken down to form pyruvic acid molecules; the Krebs cycle, in which pyruvic acid is further broken down and the energy in its molecule is used to form high-energy compounds such as NADH.

<span>Almost all female progeny show the cleft chin trait so the percent would be 100%. This trait is normal called as dimples on the cheek. When you have cleft chin, it is quite possible that they have two dominant alleles or sometimes one dominant and one recessive allele.</span>
        
             
        
        
        
Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.
- After death, the stomach contains identifiable ingested foods within two hours.
 
- Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.
 
- Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.
 
- The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).
