Which type of scientist would study the effect of wind on different bike racing helmets?
A physicist specialized in aerodynamics
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.
What is the Dobbler Effect?
The Doppler Effect is the change of frequency of a wave that is getting closer to a source. It was named after Christian Doppler who was an Austrian physicist.
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.

Explain how the founder effect can cause a change in the frequency of alleles in a population?
Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the "raw material" for natural selection.
Effect of high frequency sounds in birds?
effect of high frequency sounds
What effect does the amplifier have on the frequency of the signal?
No effect on frequency but increases it's amplitude.
What effect nationalism have on the German states and the Austrian empire?
It helped unite Germany but divided the Austrian Empire.
What is an apparent in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
What is the effect in the change in wave frequency caused by the motion of the source of the wave?
Austrian physicist Christian Johann Doppler (1803-1853)discovered that a wave's frequency changes when the source and observer are in motion relative to one another. This is known as the Doppler effect.
