b.False
c.True
d.False
Explanation:Quats or Quaternary ammonium compounds are generally colourless,odorless,non irritating and deoderizing.They are good disinfectants and also have some detergent activity.They are generally ineffective against viruses,spores and Mycobacterium tuberculosis.They are basically not suitable for any terminal infection.They act on on protein and cell membrane of microorganisms.
Hypochlorite based disinfectants are chlorine contaiming compounds.They are good disinfectants on clean surfaces but are quickly inactivited by organic matter thus reducing its biocidal activity.They are effective against wide range of bacteria, fungi, enveloped viruses and non-enveloped viruses.The free available chlorine combines with the content within organisms,thus killing it.
I would say A. Insulin and Glucagon
The definitions of "sector 3" and "stratum D", the layout of the sectors,
and the behavior of the strata would go a long way toward explaining
that mysterious absence.
Answer:
A
Explanation:
All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.
The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).
The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
