90 over 60 (90/60) or less: You may have low blood pressure. More on low blood pressure. More than 90 over 60 (90/60) and less than 120 over 80 (120/80): Your blood pressure reading is ideal and healthy. Follow a healthy lifestyle to keep it at this level.
The giant African snail is a macrophytophagous herbivore; it eats a wide range of plant material, fruit, and vegetables. It will sometimes eat sand, very small stones, bones from carcasses and even concrete as calcium sources for its shell.he shell has a conical shape, being about twice as high as it is broad. Either clockwise (dextral) or counter-clockwise (sinistral) directions can be observed in the coiling of the shell, although the right-handed (dextral) cone is the more common. Shell colouration is highly variable, and dependent on diet.
Two density-dependent limiting factors include competition and disease. Both of these factors rely on the size and density of a population because it creates conflict over limited resources (competition) and the more dense a population is, the easier it is for pathogens to spread and infect many individuals (disease).f the population density in the ecosystem were to increase, competition over these cacti would increase, making this a density-dependent limiting factor. Only a certain density of Cactus Wren can be supported in an ecosystem. Another example of a density-dependent limiting factor is disease.
