survival

Examples of survival in the following topics:

• Survival Needs

  • The are eight minimal physiological requirements for survival.
  • Air: Consisting of oxygen within a particular range of pressure, concentration, and purity is vital to survival.
  • Water: Access to a safe, clean and adequate water supply is necessary for human survival.
  • Sanitation: Proper means for the removal of human waste helps protect from deadly toxins and pathogens and is critical in promoting human survival.
  • Sleep: Seven to eight hours of uninterrupted sleep each night is optimal for human survival .

• Survival

  • These factors help an organization survive.
  • Thus, survival is one major objective pursued by company executives.
  • If revenue falls below cost for a long period of time, the firm cannot survive.
  • Survival is closely linked to new product development, profit, sales, market share, and image.
  • Name the different factors that impact a company's success and survival

• Introduction to hypothesis testing for two proportions (special topic)

  • The outcome variable of interest was whether the patients survived for at least 24 hours.
  • Let pc represent the true survival rate of people who do not receive a blood thinner (corresponding to the control group) and pt represent the survival rate for people receiving a blood thinner (corresponding to the treatment group).
  • H0 : Blood thinners do not have an overall survival effect, i.e. the survival proportions are the same in each group. pt − pc = 0.
  • HA : Blood thinners do have an impact on survival. pt − pc0.

• The Study of Population Dynamics

  • The data indicate that if a sheep in this population were to survive to age one, it could be expected to live another 7.7 years on average, as shown by the life expectancy numbers in column E.
  • Humans and most primates exhibit a Type I survivorship curve because a high percentage of offspring survive early and middle years; death occurs predominantly in older individuals.
  • These species have few offspring as they invest in parental care to increase survival.
  • Very few individuals survive the younger years; however, those that live to old age are likely to survive for a relatively-long period.
  • Trees have a Type III survivorship curve because very few survive the younger years, but after a certain age, individuals are much more likely to survive.

• Methods of Reproducing

  • Animal reproduction is essential to the survival of a species; it can occur through either asexual or sexual means.
  • Most importantly, reproduction is necessary for the survival of a species.
  • When food sources have been depleted, the climate becomes hostile, or individual survival is jeopardized by some other adverse change in living conditions, these organisms switch to sexual forms of reproduction.
  • The variations found in offspring of sexual reproduction allow some individuals to be better suited for survival and provide a mechanism for selective adaptation to occur.
  • Thus, seeds, spores, eggs, pupae, cysts, or other "over-wintering" stages of sexual reproduction ensure the survival during unfavorable times as the organism can "wait out" adverse situations until a swing back to suitability occurs.

• Temperature and Water

  • It is also rare for them to survive at temperatures exceeding 45 °C (113 °F).
  • Similarly, some bacteria have adapted to survive in extremely-hot temperatures found in places such as geysers.
  • Some animals hibernate or estivate to survive hostile temperatures.
  • Hibernation enables animals to survive cold conditions, while estivation allows animals to survive the hostile conditions of a hot, dry climate.
  • This enables the animal to wait until its environment better supports its survival.

• Value Clusters

  • For example, the 1970s saw the blossoming of the environmental movement, which put less emphasis on survival values.
  • The transition from industrial society to knowledge society is linked to a shift from survival values to self-expression values.
  • In knowledge societies, such as the United States, an increasing share of the population has grown up taking survival for granted.
  • Survival values place emphasis on economic and physical security.
  • Evaluate the separation of world values into the categories of 'self-expression' and 'survival'

• Activation of Starvation by Survival Genes

  • This in turn causes the cell to divert resources away from growth and division and toward amino acid synthesis in order to promote survival until nutrient conditions improve.

• Indian Resistance and Survival

  • Indian tribes fought over 40 wars for survival, killing at least 19,000 white settlers and soldiers and at least 30,000 American Indians.

• Thermoplasmatales, Thermocaccales, and Methanopyrus

  • There are many classes in the phylum Euryarchaeota, many of which are extremophiles, surviving in extreme conditions that are uninhabitable for most other organisms.
  • Thermophiles contain enzymes that can function at high temperatures, and can even survive at much higher temperatures, whereas other bacteria would be damaged and sometimes killed if exposed to the same temperatures.
  • Strain 116 was discovered in black smoker fluid of the Kairei hydrothermal field; it can survive and reproduce at 122 °C.
