Founder effect or population bottleneck refer to events which bring about reduction in the genetic variability of a particular specie population. Such events typically drastically reduce the gene pool of the population and produce a smaller number of population with less genetic diversity. An example of a population bottleneck is a genocide event. Such event will destroy a large percentage of the affected population leaving only a smaller population with less genetic diversity. i hope these helps.
A seismometer is used to measure the motion in the ground caused by earthquakes, volcanoes, or explosives.
Answer:
The correct answer would be:
A G C T
Human: 31 19 19 31
Cow: 28 22 22 28
Salmon: 29 21 21 29
Wheat 27 23 23 27
Yeast 31 19 19 31
Explanation:
According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.
It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:
A G C T
Human: 31 19 19 31 (A= T and G=C)
Cow: 28 22 22 28 (A= T and G=C)
Salmon: 29 21 21 29 (A= T and G=C)
Wheat 27 23 23 27 (100 - A+T = G+C)
Yeast 31 19 19 31 (A= T and G=C)
Answer:
the correct answer is B it is changeable
Explanation:
Science knowledge may change due to the development of new technics for observing investigations also through new ways of thinking or framing the questions asked.
