A 3-year-old boy was running full speed and tripped over his toy, falling on his right leg. An X-ray shows an isolated nondisplaced distal spiral fracture of the tibia. Which of the following is the next best step in the treatment?
a. Orthopedic consult for casting and further treatment
b. Observation at this fracture spontaneously heals in toddlers
c. Obtain a skeletal survey
d. Obtain work up for bone cancer

i think the miocene epoch spans the time from 23 million to 12 million years ago.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
