Afourth type of restriction enzyme is identified that cleaves at precise locations like a type ii enzyme, but it also occasionally makes mistakes and cuts elsewhere. would this type of enzyme be a useful enzyme to use in molecular cloning?

No, in molecular cloning cutting mistakes can lead to in correct ligation

C) No, because cutting mistakes could lead to incorrect cloning.

Explanation:

in molecular cloning, if you want to insert a specific gene of interest in to specific vector, the selection of enzyme and strategy before that is very important.  The restriction enzyme should be selected which restrict at the desired location in the cloning sites. Any mistake in these selection or undesirable mutation mistakes can lead to in correct or unsuccessful cloning results.  

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.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
