Document Summary

Any substance seized in violation of law in sale, manufacture, Glass particle/fragment transferred during crime + include. Tire markings, shoe prints, soft soil depressions, other tracks: blood, semen, saliva dried/liquid (include cigarette butts that may contain. Any device containing explosive charge + objects removed form. Natural/synthetic fiber transfer = may be useful to establish relation: documents. Any handwriting/typewriting submitted authenticity or source: drugs, explosives, fibers, fingerprints. Latent/visible: firearms and ammunition, glass, hair. All items that contains it that could link person/object to certain location (ex. soil embedded in shoes + safe insulation on garments) Any object suspected of containing impression of another object served as tool in crime (ex. crowbar, screwdriver impressed into/scrape wall surface) impact vegetative matter on garments/tools. Process of determining substance"s physical or chemical identity; drug analysis, species determination, explosive residue analysis = typical examples. Item suspected of containing firearm discharge residues. Stolen property submitted to lab to restore erased.

<p>Robert recently watched a documentary on the Fairchild-Republic A-10 Thunderbolt II (‘Warthog’). This single-seat close air support aircraft is entirely designed around a seven-barrel 30mm GAU-8/A Avenger Gatling gun that fires 3900 rounds (bullets) per minute with a muzzle velocity of approximately 3250 ft/s to engage armored targets (especially tanks) at distances approaching two miles. Aluminum jacketed combat ammunition loads use a 4 to 1 ratio of depleted uranium (DU) armor-piercing incendiary (API) and high-explosive incendiary (HEI); rounds are typically 11.4 in long and mass 1.53+ lb. The rated accuracy specifies 80% of the fired rounds impact within a 20ft radius circle 4000ft downrange, with a drop of 10ft. Due to the enormous recoil of this gun (and to conserve ammunition), pilots typically fire the cannon in 2.00s bursts. Using SI units, calculate the engine thrust necessary to maintain constant airspeed during the interval when the cannon fires. Assume the plane is in level flight and that 56% of the mass of each round is the projectile (each API projectile contains a 0.66lb DU sabot in a Ti-Al jacket)<br /><br />Note: All momentum analyses must begin with a FBD*, include an isolation test, and utilize the law of momentum conservation.</p>

6) ene expression controlled by the epigenome is flexiblebecause the epigenome can respond to environmental signals

Select one:

a) in a time-dependent manner.

b) because the chemical bonds in methyl groups can readilybend.

c) by changing the DNA sequences of genes.

d) similarly to the way that the food supply controlsappetite.

e) in a way that is completely unpredictable.

7) Which of the following can be determined from the DNAfingerprint of an individual?

A DNA fingerprint can reveal

Select one or more:

a) the indvidual's gender (male or female).
the individual's gender (male or female).

b) the individual's blood type.

c) the individual's biological family relationships (paternity,etc.).

d) how many siblings (brothers and sisters) are found in thefamily of the individual whose DNA is sampled.

e) the individualâs risk of heart disease.

8) CODIS is the FBI abbreviation for a database containingthe

Select one or more:

a) digital images of convicted felons.

b) skin fingerprints of convicted felons.

c) genome sequence from the Human Genome Project.

d) DNA libraries available from published research findings.

e) DNA fingerprints of convicted offenders, arrestees, and crimescene samples.

9) Do identical twins have identical skin fingerprints?

Select one:

a) No, because the twins' skin fingerprints are left-rightmirror images of each other due to the mirror image symmetry thathappens when identical embryos split apart from one originalembryo.

b) It depends. If the identical twins are in the same placenta,they will have the same fingerprints. If they are in separateplacentas, they will have different fingerprints.

c) Yes, because identical twins have the same genome and genesthey will have identical skin fingerprints.

d) No, because the development of the skin fingerprints areinfluenced by the environment in the uterus.

e) Yes, because the twins' skin fingerprints are inheriteddirectly from the mother without a contribution from thefather.

In the process of Somatic CellNuclear Transfer in which Dolly the sheep was cloned, an adultnucleus was inserted into a denucleated egg cell. How is theepigenome related to this process?

Select one:

a) The methylation of the adult nucleus must be removed so thatthe cloned zygote can become a viable embryo and fetus.

b) Dolly's epigenome was a mixture of the epigenomes of thedonor mother and of the egg cell from the surrogate mother.

c) The epigenome of the adult nucleus directs development of thecloned zygote.

d) The epigenome of the female surrogate that carried thepregnancy to term becomes impinted on the genome of the clonedzygote.

e) The epigenome of the egg cell nucleus is transferred to thedonor cell nucleus.
