The correct answer is biological evolution.
Biological evolution refers to the procedure via which the features of species modify over consecutive generations, by means of natural selection and genetic variation. It is most usually illustrated as modifications in the frequencies of the gene in the populations.
Evolution by natural selection is one of the followed authenticated theories in the history of science, encouraged by proof from a broad kind of scientific disciplines involving geology, palaeontology, developmental biology, and genetics.
T. it is described by what the Earth is made of and where it is placed.
Answer:
0.091 m/s
Explanation:
Given in the question that,
wavelength of a wave = 7mm
frequency of a wave = 13 hertz
Formula to use
<h3> f = v / λ </h3>
here f = frequency in hertz
v = velocity in m/s
λ = wavelength in m
1 mm = 1x10
7mm = 7x10
Plug values in the formula
13 = v / 7x10
v = 13(7x10^{-3})
v = 0.091 m/s
