It targets and gradually weakens the body's immune system by damaging cells called CD4 T cells. This damage means that, over time, the body becomes less able to fight off other infections. If the immune system becomes impaired enough, infections that are typically mild can be life threatening.

The administration method that takes the longest time for the drug to reach the brain is __________.
photoshop1234 [79]

Oral ingestion or swallowing is the administration method that takes the longest time for the drug to reach the brain. When using this method, the drug is swallowed through the mouth, moves to the stomach and then into the bloodstream before it can be transported to the brain. This means that it takes longer for a swallowed drug to start functioning than it does with other methods of administration such as injecting.

This biological level of organization is represented by all three steps of the gene expression products. ____________
Licemer1 [7]

Answer:

The biological level of organization represented by all of the three steps of gene expression products is <em>the central dogma of molecular biology.</em>

Explanation:

DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.

The functional products of most known genes are polypeptides.  Genes that specify polypeptides are called protein-coding genes.

Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.

The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
