A diseases may be classified as either communicable or non-communicable. Communicable diseases are caused by pathogens who inhabit a host, man (I'm not saying man is the only host or man is necessarily the final host; there could be many host) who in turn passes the disease to another. Pathogens are viral, bacterial, parasitic and fungal. There are several stages before the pathogen metamorphoses into a full-blown disease. The stages in which several events happen builds up before the pathogen affects the final host is called a communicable disease chain. There are six stages ( Pathogen, reservoir, portal of ext, mode of transmission, portal of entry and susceptible host) in the communicable disease chain but the step a nurse shouod take is 1. Destroy the second link (Reservoir) by thoroughly sanitizing the environment. Obviously, this is where the Pathogens live. If the reservoir is taken care of; there's no way they could infect the host.

Genes determine the _________of an individual.

Fiesta28 [93]

Answer:Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.

41) a particular triplet of bases in the template strand of dna is 5' agt 3'. the corresponding codon for the mrna transcribed i

KiRa [710]

A particular triplet of bases in the template strand of DNA is 5' agt 3'. the corresponding codon for the mRNA transcribed is 3' UCA 5'

It serves as a link between DNA's genetic code and proteins' amino acid sequences.

The codons in the messenger RNA (mRNA) are complementary to the nucleotide sequence on the DNA template strand.

Then it controls the synthesis of amino acids with the aid of tRNA and ribosomes.

Its name, messenger RNA, refers to the fact that it carries genetic information. The single strands of adenine, cytosine, guanine, and uracil that make up the mRNA molecule are held together by a sugar phosphate backbone.

Two codons: His, Lys, Phe, Tyr, Asn, Asp, Cys, Gln, Glu, Codons Ile, STOP, and three ("nonsense"). Ala, Gly, Pro, Thr, and Val are the four codons. None of the five codons.

Question 8 of 10

Fynjy0 [20]

I believe it’s A but I’m not too sure

Reason; Warm air rises, and when it rises it becomes cooler. ... If the pressure of the surrounding air is reduced, then the rising air parcel will expand. The molecules of air are doing work as they expand. This will affect the parcel's temperature (which is the average kinetic energy of the molecules in the air parcel).
