Mitochondria have two membranes: one is the outer mitochondrial membrane and the other is the inner mitochondrial membrane. Between these two membranes, there is a mitochondrial membrane space. Mitochondrial matrix is present inside the mitochondria. NADH and FADH2 are synthesized in the cytoplasm and the mitochondrial matrix through glycolysis and Krebs cycle. These high energy compounds enter the inner mitochondrial membrane, transport the electrons in the electron transport chain, produce H 2 O from oxygen, and produce ATP molecules by the four enzyme complexes. There are four complex enzymes present in the inner mitochondrial membrane for the transfer of electrons, and synthesis of ATP and water molecules.

Which of the following statements about hydration is true? Absence of thirst is a reliable indication that an individual is adequately hydrated. All of these statements are true. Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration. Urine that is the color of apple juice indicates dehydration. I don't know yet

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?
