What is the process by which a trait present in an ancestral organism is modified by natural selection over time in descendants
dolphi86 [110]

Answer:

d) descent with modification

Explanation:

According to my research on Darwin's theory of natural selection, I can say that based on the information provided within the question the term being described is called descent with modification. This basically refers to the most dominant traits being passed down from generation to generation, and being modified little by little in each lineage. Which is done through natural selection.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

.Answer:

1. s-waves

2.  s-waves

3. p-waves

4.  p-waves

5.surface waves

Explanation:

  • A<em> </em><u><em>P-wave</em></u> is one of the two main types of elastic body waves, called seismic waves in seismology. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P-waves may be transmitted through gases, liquids, or solids.
  • a <u><em>surface wave</em></u><em> </em>is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities
  • <u><em>S-waves</em></u>, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.
