Answer:
The mark called Rifling might link the bullet to a specific weapon.
These are Patent fingerprints.
Explanation:
Modern-day handguns are produced of a particular blueprint that determines their specifications. One major characteristics trait of this specification is known as Rifling.
Rifling is an act or process of making the grooves in a rifled cannon or gun barrel. The system of grooves in a rifled gun barrel in which one side of the groove is made deeper than the other side to facilitate loading with shots having projections is enough to determine what brand/model of specific weapon is being used.
The only type of fingerprint that can be collected through such a crime scene in a blood smear is Patent fingerprints. This type of fingerprint is collected by using a photographic technique that uses high resolutions & a forensic measuring scale.
Answer:
Botulinum toxin
Explanation:
Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.
This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.
Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.
Aerobic respiration involves the breakdown of glucose, producing carbon dioxide, water, and ATP, which is energy. This process is followed by three steps: Glycolysis, the Krebs Cycle, and electron transport.
Glycolysis takes place in the cytoplasm of the cell. Glucose is broken down into two pyruvates, which are 3 carbon molecules. NADH, a large molecule is also produced because the pyruvate is oxidized or “groomed”. Pieces of the molecule is chopped off, releasing NADH, acetyl CoA, and C02, which diffuses out of the cell.
In the Kreb’s cycle, AcetylCoA is brought into the cycle, where a set of reactions occur to release 2 ATP, NADH, FADH2, and C02.
Oxidation phosphorylation is the third step, including the electron transport chain. Electrons are delivered by NADH and FADH2. Hydrogen atoms go through a redox reaction, meaning atoms either gain or lose electrons. Oxygen is highly electronegative, so it pulls electrons through the electron transport chain. Electrons provide the energy to pump hydrogens across the membrane. Eventually, protons will flow down the gradient through the ATP synthase, creating ATP.
Take a sample of amniotic fluid can identify a genetic disorder in a fetus. So option (c) is the correct answer.
An amniocentesis is a prenatal test that can diagnose genetic disorders and other health problems in the fetus.
Genetic amniocentesis is usually performed between the 14th and 20th weeks of pregnancy. An amniocentesis performed before 14 weeks of gestation may cause additional complications. Reasons for genetic amniocentesis include: A positive prenatal screening test result.
Amniotic fluid is the clear fluid that surrounds your baby in your belly during pregnancy. This fluid provides a cushion that protects the baby from injury and gives it room to grow, move and develop.The amniotic fluid also prevents the umbilical cord from getting caught between the baby and the walls of the uterus.
