What is a bioindicator?
A biological indicator is a device to monitor the sterilization process that consists of a standardized population bacterial spores known to be resistant to the mode of sterilization being monitored. Biological indicators indicate that all the parameters necessary for sterilization were present.
Which level of classification has greatest similarity?
The levels of classification for all organisms is as following (from broadest to narrowest) Kingdom, Phylum, Class, Order, Family, Genus, Species. So organisms that have the same species will be most alike.
How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil record?
Where are you people getting these ill posed questions? What level? Transitional forms! At the species level this would be explained as a rapid (geologically rapid) speciation event followed by years of stasis, where little morphological change is taking place.
What is a fossil that can be used as a marker in time called?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
What is correct order in which to assess level of arousal?
Determine the arousal state first, using minimal stimuli and increasing intensity as needed. Start with auditory stimuli, move to tactile stimuli, and use painful stimuli as a last resort.
How indicator species are used to assess pollution in the environment?
Indicator species can be used in one of two ways: * the indicator species is one which easily affected by the pollutant. Specimens are kept in an area and observed. When they show distress the pollution rate is climbing, and this happens before the hardier species are impacted. Think of canaries in coal mines. * When a biologist inspects an ecosystem he keeps track of the population and the species present. If only hardy (pollution resistant) species are present the ecology has become degraded. If sensitive species are present the environemt is still good.
Which algae is pollution indicator?
Certain species of algae, such as diatoms and filamentous algae, are commonly used as pollution indicators. These algae are sensitive to changes in water quality and can serve as early warning signs of pollution in aquatic ecosystems. Monitoring their abundance and diversity can help assess the health of a water body and the level of pollution present.
What is a pollution indicator?
living organism that shows the level of pollution in an area through changes in iys distribution or abundance
What is the significance of sound pressure level in measuring the intensity of noise pollution?
Sound pressure level is important in measuring noise pollution because it quantifies the intensity of sound waves in the environment. It helps us understand how loud and potentially harmful the noise is to human health and the environment. By measuring sound pressure level, we can assess the impact of noise pollution and take steps to mitigate its effects.
What is a water level indicator?
A water level indicator shows how high the water is.
What is an idicator?
Indicator can be defined as a benchmark for the presence or absence of a condition. Example: pH indicator indicates the pH of the given sample. Environmental bioindicator indictes the environmental level of pollution
What is an indicator in portable water?
An indicator in potable water is a substance that changes color in the presence of specific contaminants or parameters, such as pH level, chlorine concentration, or presence of bacteria. Indicators are used to quickly assess the quality of water and determine if it meets safety standards for consumption.
What is the working of oil level indicator of transformer?
The oil level indicator in a transformer is used to show the oil level.
What is pollution density?
Pollution density refers to the concentration of pollutants in a specific area, often measured in units such as parts per million (ppm) or micrograms per cubic meter. It provides information on the level of pollution in the environment and can be used to assess its potential impact on human health and the ecosystem. High pollution density can lead to various health problems and environmental degradation.
Which type of level indicator is used in chlorine storage tank?
A common type of level indicator used in chlorine storage tanks is a magnetic level indicator. This type of indicator uses a float with a magnetic element inside the tank that moves up and down with the liquid level, causing the external indicator to change accordingly. Magnetic level indicators are often preferred for chlorine tanks due to their reliability and ability to provide accurate level readings.
Where is the gearbox oil level indicator on a vw caravelle vr6 auto?
There is no level indicator on the gearbox. The oil is checked by topping it up.
