Natural selection
The grouping of viruses is based on the particular species. Viruses are also living organisms which are divided into specific genus and species.
The presence or absence of the appropriate receptors.
invertebrates
Because they die in the presence of catalase. They also die in the presence of oxygen, due to the absence of superoxide dismutase and catalase. It converts the lethal superoxide inside their cells due to the presence of oxygen.
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen.
Proteins
The grouping of viruses is based on the particular species. Viruses are also living organisms which are divided into specific genus and species.
Reproduction is directly linked to the stability of the population of species because it helps in replacing the aging population with the new population and thus ensures the survival of the species. In the absence of reproduction one particular species will disappear with time.
The flow of an activity is limited by the presence or absence of one or many factors necessary for survival. That factor is called as limiting factor.
The Presence-Absence (P-A) test is a presumptive detection for coliforms.
