The movement of organism into a given area from another area is called?
Population Shift
What does left shift in CBC mean?
Shift to The left means increase in the immature white blood cells.
What type of mutation is responsible of new variations of a trait?
420 blaze it
Will a plant with the largest root system have the greatest chance of survival?
if you mean the deepest roots..not necessarily..draught could kill it or a shift in its water supply by earthquake. ..therefore a wide circumferance with many branches with a single tap root is better...many places to gain a source of nutrients and/or water.
What is niche compression?
niche shift
What ''shifts'' when you have a Doppler shift in starlight?
What shifts is the frequencies of the light. This can be observed by certain lines in the spectrum, which have very specific positions (frequencies).
How do you surpres 3rd harmonics?
you match the frequencies but with a 90 degree phase shift
What are the applications of RC phase shift oscillator?
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
What is the application of frequency shift keying?
amplitude shift keying is a form of modulation in digital signal that variation in the amplitude of carrier wave. application of ask: *used mainly for radio frequencies
What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
What does the abbreviation STS in relation to hearing stand for?
STS stands for standard threshold shift, which is the criteria for measuring occupational hearing loss. It is an average shift from the baseline measurement in either ear of 10 dB or more at 2000, 3000 and 4000 Hz. These frequencies are the most important frequencies in communication and the most sensitive to damage by industrial noise exposure.
What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
What is it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
What wavelenghts are used to study star's?
To make a long story short, all of them. Various properties of starts can be studied by measuring the frequencies and corresponding intensities of electromagnetic radiation from a star. Assuming a star is not moving with respect to the Earth (or, put more simply, is moving as fast as the Earth is and in the same direction), the intensities of the wavelengths emitted by the star can be seen from Earth as having a bell curve distribution whose peak corresponds with the star's temperature. However, this bell curve distribution is not perfect. At several specific frequencies, the intensity of emitted light is greatly decreased. The frequencies influenced by this effect and the degree that this effect occurs are dependent on the component elements and corresponding concentrations of these elements. Therefore, by analyzing the frequencies that are "missing" from the electromagnetic spectrum, one can derive the chemical composition of the star. If the star is moving with respect to the Earth, this distribution of light is distorted even more. As a consequence of relativistic physics, the wavelengths of light emitted from the star will appear to have a higher frequency as seen from the Earth than what was emitted if the star is moving toward the Earth (this is called "blue shift", as visible colors appear more blue). Conversely, the Earth will see lower frequencies of light than were originally emitted if the star is moving away from the Earth (this is called "red shift", as visible colors appear more red). However, since the distribution of light emitted from the star has "missing" frequencies, and since the original emitted frequencies are known for these "missing" frequencies (as they correspond with the frequencies emitted by known compounds), the entire distribution of light can be shifted back to its rightful place. Moreover, the amount of this shift is dependent of the relative speed between the Earth and the star; therefore, the star's speed can be determined from the star's light as well.
Is it possible to become famous without successful parents?
A similar all-pass filter can be implemented by interchanging the position of the resistor and capacitor, which turns the high-pass filter into a low-pass filter. The result is a phase shifter with the same quadrature frequency but a 180 degree shift at high frequencies and no shift at low frequencies. In other words, the transfer function is negated, and so it has the same pole at -1/RC and reflected zero at 1/RC. Again, the phase shift of the all-pass filter is double the phase shift of the first-order filter at its non-inverting input.
How do you get the pumpkin helmet on poptropica?
Press control+shift+p and your poptropican will have a pumkin head (helmet) other stuff: control+shift+r= character change (randomly changes character into a different person), control+shift+s=skin color change (changes skin color) made by AnimatorJazz486 on youtube
What is a wave caused by a sudden shift in the ocean floor called?
A wave caused by a sudden shift in the ocean floor is called a tsunami.
