Answer:
Ur answer
Explanation:
If the bacteria grows for six hours each bacterium will divide <em>3 times/hour * 6 hours = 18 times.</em>
Every time the bacteria reproduce the number doubles.
Sedimentation is the reason of Ripple marks.
Water flowing over loose sediment creates bed formations by displacing the sediment with the flow, which is what causes ripple imprints. In contrast to ripples, which are typical of shallow water deposition and can also be brought about by wind blowing over the surface, bed formations are related to flow velocity and sediment size.
<h3>How do ripple marks work?</h3>
Sand ripples, represented by the marks observed on beach sand or the bottom of a shallow stream, are created by forces like wave-related forces or wind-related forces, which are characteristic of the deposition of inorganic materials in shallow water.
<h3>What is Sedimentation ?</h3>
The process of allowing particles suspended in water to separate under the influence of gravity is known as sedimentation. Sludge is the term for the sedimentary particles that form from the suspension during the water treatment process.
so, Ripple marks are the result of sedimentation during deposition.

(studying this for AP Bio test, feels good man)
Fossil Records: shows the large amounts of time in which simple organisms have evolved into complex organisms
Comparative anatomy: in many different types of vertebrates, many bones are similar, indicating a common ancestor in the past, these bones are homologous in different vertebrates
Comparative embryology: many embryos of developing vertebrates will look similar and develop similar structures in its respective time in the womb
Bio Geography: many fossils and creatures are found in such distant places that it is impossible for them to have migrated, only because the Earth was once a large land mass (Pangea). And many animals of the same special developed some differences to cope with the surrounding environment.
Molecular Biology: similar DNA sequences, genomes
Observed evolutionary change: changes in the alleles of a population, mutation, genetic drift, etc.
