Life is defined by 7 main characteristics, known by the acronym:
MRS GREN
M ovement
R espiration
S ensitivity (ability to sense)
G rowth
R eproduction
E xcretion
N utrition
So how many do viruses fulfil? Not 1, 2, 4, 6 or 7.
They can kind of react to their surroundings and they can reproduce but only 2/7 qualities probably doesn't qualify them to be 'living'.
L-cysteine and L-valine
Penicillin is a secondary metabolite commonly found in the filamentous
fungi and they are synthesized from the amino acid precursors L-cysteine, L-valine and l-α-aminoadipic
acid. β-lactam antibiotic penicillin are antibiotics commonly used for the
treatment or therapy of infectious diseases.
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.
Oxidation and reduction. ... It refers to electrochemical processes<span> involving electron transfer to or from a molecule or ion changing its oxidation state. This reaction can occur through the application of an external voltage or through the release of chemical energy.</span>
