What CD4 stand for? In molecular biology, CD4 (cluster of differentiation 4) is a glycoprotein found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. What is the normal CD4 count for a healthy person? A CD4 count is typically reported as a count of cells (expressed as […]
How can I represent relationships between two variables?
How can I represent relationships between two variables? Correlation Correlation analysis seeks to identify (by a single number) the degree to which there is a (linear) relation between the numbers in sets of data pairs. Regression analysis is used to determine if a relationship exists between two variables. 1)Generation of the regression line and equation […]
What happens to Wavefunctions as n increases?
What happens to Wavefunctions as n increases? Note that as n increased, the energy of the wavefunction increases (Equation 3.5. 12) and both the number of nodes and antinodes increase and the frequency of oscillation of the wavefunction increases. When the particle strikes the wall of the well it bounces off completely true or false? […]
How can you classify map projections in terms of their distortion characteristics?
How can you classify map projections in terms of their distortion characteristics? A common method of classification of map projections is according to distortion characteristics – identifying properties that are preserved or distorted by a projection. The distortion pattern of a projection can be visualized by distortion ellipses, which are known as Tissot’s indicatrices. What […]
What Hz is harmful?
What Hz is harmful? The most dangerous frequency is at the median alpha-rhythm frequencies of the brain, 7 hz. This is also the resonant frequency of the body’s organs. What frequency can kill humans? 7 hz What is the death frequency? As of 2020, the CIA estimates the U.S. crude death rate will be 8.3 […]
How do metal leaf Electroscopes work?
How do metal leaf Electroscopes work? An electroscope is a device that detects static electricity by using thin metal or plastic leaves, which separate when charged. Electrical charges move to the metal and down to the foil leaves, which then repel each other. Since each leaf has the same charge (positive or negative), they repel […]
How do you increase the amplitude of a sound wave?
How do you increase the amplitude of a sound wave? In theory, a sound wave can have any amplitude, and we can boost a wave by multiplying its samples with any arbitrarily large number. What is relation between frequency and voltage? As the voltage increases so does the power out of the area and frequency […]
Which of the following will not affect the rate of evaporation?
Which of the following will not affect the rate of evaporation? Explanation: The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. But not on the mixed absolute heavy impurities. At what temperature does water start evaporating? 212° F How do you calculate the evaporation rate of water? I […]
What is the slowest spreading ocean?
What is the slowest spreading ocean? The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end. What is the difference between a fast spread and a slow spread? Steep steps in the seafloor that can […]
What can charge an insulator?
What can charge an insulator? A conductor is a substance that allows charge to flow freely through its atomic structure. An insulator holds charge within its atomic structure. Objects with like charges repel each other, while those with unlike charges attract each other. What is difference between conduction and induction? In conduction, the neutral body […]
