Relate genetic variation and mutations to each other?
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.
Does frequency affect wave speed?
The speed of a wave doesn't depend on its frequency.REASON:According to the formulaV=frequency * Lambdaso,V/ Lambda= frequencyHere,Frequency is inversely proportional to the wavelength. so, If we increase the value of frequency then by same amount frequency will decrease and will cancel out the effect of each other the "V" will remain constant.
What are the two types of genetic drift?
There are two types of genetic drift, there is a the population bottle neck effect and the founder effect. The population bottle neck effect is when a population greatly decreases in size due to some random ecological event and the small population has a greater chance of genetic variation. The founder effect is a variation of the bottle neck effect in which a small portion of a larger population to branch off or get "isolated" from the larger population and have a greater chance of genetic variation. Have fun and hope this helps.
A small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly (six fingers). Many generations that followed had cases of?
The Founder Effect The founder effect is when a few individuals of a species form a new population. The gene pool composition, therefore, is not reflective of the gene pool of the original population. Think of this as a small number of people starting their own colony. This is an example of the Founder effect because Polydactyly is a dominant trait. And in a large population, it will be rare finding a person with a 6th digit. In a smaller population, however, polydactyly has a higher frequency of this allele, because the smaller the population, the higher the sensitivity for inbreeding and lower genetic variation. So, polydactyly (dominant allele) + Increase inbreeding= Higher polydactyly allele frequency.
Who is the Doppler effect named after?
The Doppler effect is named after Austrian physicist Christian Doppler, who first described the phenomenon in 1842. He realized that the frequency of waves changes depending on the relative motion between the source of the waves and an observer.
Who was the Doppler Effect named after?
The Doppler Effect was named after Austrian physicist Christian Doppler, who first described it in 1842.
What is the Dobbler Effect?
The Dobbler Effect, also known as the Doppler Effect, is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. This effect is commonly experienced with sound waves, where the pitch of the sound is perceived higher as the source moves closer and lower as the source moves away.
What is a dopper effect?
The Doppler effect is the change in frequency or wavelength of a wave for an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
What is the definition of Doppler?
An Austrian physicist, Christian Doppler, is best known for the effect named after him, the Doppler effect, which he proposed in 1842. It is the change in frequency of a wave as measured by an observer in motion relative to the source of the wave.The Doppler effect (or Doppler shift) is the change in frequency and wavelength of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is increased (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is decreased during the receding motion. The higher or lower frequency alters the pitch of the sound as heard by a stationary listener, making it sound higher-pitched or lower-pitched.
What is the effect of carrier frequency variation on AM signal?
If the modulation is to large your bandwidth will be to wide in other words the frequency shift will be larger than normal that will result in a distorted audio signal at the receiver
Why is the word hertz used to describe frequency?
The word 'hertz' comes from Heinrich Rudolph Hertz, a German physicist who discovered the electrical waves (cycles), as well as the photo-electric effect.

When were Doppler ultrasounds invented?
Christian Doppler discovered the Doppler effect in 1842. He observed that the frequency of sound changes as the object of the sounds moves and the detector of the sound moves. Radar and medical devices use the Doppler effect to locate and provide images of scanned objects.
Who discovered the Doppler effect?
Christian Doppler did not invent Doppler Radar. He described what is now known as the Doppler effect in 1842 in Austria. It is used to describe the behavior of waves (such as light or sound) that are emitted by a moving object. Doppler radar, which utilizes the Doppler effect, was developed in the United States during World War II.
What effect nationalism have on the German states and the Austrian empire?
It helped unite Germany but divided the Austrian Empire.
What effect does the amplifier have on the frequency of the signal?
No effect on frequency but increases it's amplitude.
