1.

Forensic entomology uses

pollen in the hair
tree rings
the stages of insect life cycles on the body
fingerprints
2.

PCR is used in forensics to

cut DNA
separate DNA fragments
stain DNA
amplify small samples of DNA
3.

Time of death can be estimated from

hair colour
blood group
height
body temperature, degree of muscle contraction, extent of decomposition and forensic entomology
4.

Rigor mortis occurs because

muscles relax
the body warms
ATP runs out, so muscle fibres remain contracted
blood clots
5.

The role of microorganisms in decomposition is to

preserve the body
prevent decay
break down organic matter, recycling carbon
produce oxygen
6.

DNA profiles differ between individuals because

everyone has different genes
the number of repeats in short tandem repeats (STRs) varies
DNA is random
proteins differ
7.

Identical twins have

different DNA profiles
no STRs
different numbers of chromosomes
identical DNA profiles
