I believe the answers to this is C and D.
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.
No rats cannot pass on memories to their offspring about a particular maze. Such inheritance has not been proven and doesn't seem to exist. Neither does any biological theory or idea at the moment account for such a thing as passing on memories.
Answer:
Oxygen
Explanation:
Oxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight.
Answer:
The correct answer would be zero.
Water potential measures the tendency of water to move from one area to another.
It is denoted by the symbol ψ.
It is determined by two main factors:
Solute potential (ψs): It is determined by solute concentration.
Pressure potential (ψp): The pressure exerted on a solution. It can be negative or positive.
ψ = ψs + ψp
Thus, in an open container, the water potential of pure water would be zero as pure water does not contain any solute (that is, ψs = 0) and pressure potential is zero (ψp = 0) in an open container.
