If a Member decides to introduce a bill, CRS analysts can assist the legislator ( or his or her staff ) in clarifying the purposes of the bill, identifying issues it may address, defining alternative ways for dealing with them, evaluating the possible advantages and disadvantages of each alternative, developing information and arguments to support the bill, and anticipating possible criticisms of the bill and responses to them.

If a child is exposed to infection diseases then the cell defense will be stimulated via Th1 cells causing a reduction of Th2 cells and subsequently a reduction of antibody stimulation by Th2 and therefore a lower risk of developing an allergic disease such as asthma.

If evolutionary processes are blind to the difference between function F being performed by conscious organism O and non-conscious organism O *, it is unclear what adaptive advantage consciousness could provide.

If an organism ( such as bacteria ) attaches to a valve surface and forms a vegetation, the host immune response is blunted.

If the chemistry is right, the organism ( or fragment of organism ) can act as a nucleus for the precipitation of minerals such as siderite, resulting in a nodule forming around it.

If a mutation occurs within a gene, the new allele may affect the trait that the gene controls, altering the phenotype of the organism.

If an organism lives half as long as others of its species, but has twice as many offspring surviving to adulthood, its genes will become more common in the adult population of the next generation.
