What are the 2 biological effects of ionizing radiation? The biological effects of ionizing radiation are due to two effects it has on cells: interference with cell reproduction, and destruction of cell function. Which radiation is responsible for oncogenic transformation? Class I PI3K consists of four isoforms, PI3K α, β, γ, and δ, each with […]
What are 3 ways an object can be charged?
What are 3 ways an object can be charged? In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction. What is a charged object give three examples? There are three ways that objects can be given […]
What are people doing about ocean acidification?
What are people doing about ocean acidification? The most effective way to limit ocean acidification is to act on climate change, implementing solutions to dramatically reduce the use of fossil fuels. If we dramatically cut our global warming emissions, and we limit future warming, we can significantly reduce the harm to marine ecosystems. What are […]
What are three different types of precipitation?
What are three different types of precipitation? The most common types of precipitation are rain, hail, and snow. What is the major form of precipitation? There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all […]
Do spiders have feelings?
Do spiders have feelings? In short, biologically, spiders do experience feelings. Their neurons react to stimuli much like you and me; reactions that are reasonable for the situations that they’re in. However, in terms of emotional feelings, the general consensus is that there isn’t much. Why are humans afraid of spiders? Arachnophobia comes from the […]
Why is velocity zero at pitot tube?
Why is velocity zero at pitot tube? At the open end of the pitot tube the velocity of the fluid becomes zero. But that should result in accumulation of liquid inside the pipe which is not possible. Why is stagnation point important? The stagnation point represents the location of the start of the leading edge […]
What is the best solvent for recrystallization?
What is the best solvent for recrystallization? For a solvent pair, the first solvent should readily dissolve the solid. The second solvent must have a lower solubility for the solute and be miscible with the first solvent. Common solvent pairs include ethyl acetate and hexane, toluene and hexane, methanol and dichloromethane, and water and ethanol. […]
What is the shortest period of time?
What is the shortest period of time? Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes […]
What is the purpose of frequency table?
What is the purpose of frequency table? The frequency table records the number of observations falling in each interval. Frequency tables are useful for analyzing categorical data and for screening data for data entry errors. Note that we will refer to two types of categorical variables: Categorical and Grouping or Break. How do you know […]
What is a dimensional formula?
What is a dimensional formula? Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and derived units in terms of dimensions is called dimensional formula (equation). In mechanics the length, mass and time are taken as three base dimensions and are represented by letters L, M, T respectively. What unit […]
