Sickle cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. this genetic disease is recessive. if two individuals who have one recessive gene have four children, what percentage of the children will show symptoms of sickle cell disease?

25 percent
100 percent
50 percent
75 percent

25 percent chance of sickle cell disease

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
