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.
Chemical eqn of photosynthesis is
CO₂ + H₂0 —> C₆H₁₂O₆ + O₂
It was used by Hubble to measure velocities of galaxies
I would likely go with A) Country B will have a high level of poverty because the richness and even distribution of Country A's resources reduce the probability of poverty. The citizens have greater access to resources that will sustain them. In Country B, however, the low distribution of the resources means citizens in areas where they are not as concentrated will suffer and likely have a high level of poverty.
