Answer:
A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway. This lower activation energy means that a larger fraction of collisions are successful at a given temperature, leading to an increased reaction rate.

Central venous access device refers to a small, flexible tube positioned in large veins for an individual who needs continuous access to the bloodstream. Such devices are usually considered as catheters or venous access ports, as they permit regular access to the veins without application of deep needle sticks.
All the CVADs require a dressing immediately post insertion of the device to reduce the threat of infection. It requires a dressing surrounding the entrance to the tunnel of the skin unless and until the wound gets healed. This can take about 10 to 14 days based on the condition of the patient.
Answer:
in rna the strand would be <u> UAGGCGUA</u>
G goes with C and A goes with U ( unless there is a T within the strand already then its an A that airs up with it )
Explanation:
but if its in DNA the strand will be <u>TAGGCGTA </u>
G goes with C T goes with A
Answer:B. nucleic acids to amino acids
Explanation: During translation, proteins are synthesized from messenger RNA molecule. Messenger RNA (mRNA) is a type of ribonucleic acid that contains genetic codes which code for amino acids. A genetic code or codon is a triplet of nucleotide (three nucleotide molecules) that codes for a specific amino acid. During translation, the genetic code in an mRNA is read by the ribosome and the information is converted to an amino acid sequence by transfer RNA (tRNA) which gets the amino acid coded for by the codon and attaches it to the growing polypeptide chain.
Transfer RNA is responsible for fetching the correct amino acid coded for by the codon from the cytosol and attaching it to the growing polypeptide sequence.
