A scientist wants to test whether the pH, salinity, and temperature of seawater impacts coral development. He sets up an experim

ent with three conditions: Aquarium 1: Normal pH, normal salinity, normal temperature Aquarium 2: High pH, high salinity, high temperature Aquarium 3: Low pH, low salinity, low temperature He finds that coral grow the least in Aquarium 2. He concludes that coral does not grow well in conditions with high salt. Why is this an invalid conclusion?

He was testing more than one variable in the aquarium which would change the outcome of the experiment. it could have been the Ph levels or the temperature of the water.

In the given experiment, the scientist is checking for the effect of more than one variable on the development of the coral, which includes the pH, the salinity, and the temperature. The conclusion that the coral do not grow in the water with high salinity is wrong as in that aquarium, the pH, and the temperature were also high. They could also have been the factors behind the decreased growth of the corals. One variable should be tested at a single time to arrive at a valid conclusion.

<h2>Galapagos Finch </h2>

Explanation:

Darwin's finches are a classical example of an adaptive radiation

  • Darwin's finches common ancestor arrived on the Galapagos about two million years ago,during the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behavior
  • Changes in size and form of the beak have enabled different species to utilize different food resources such us insects, seeds, nectar from cactus flowers all driven by Darwinian selection
  • From 1831 to 1836, Darwin was part of a survey expedition carried out by the ship HMS Beagle, which included stops in South America, Australia, and the southern tip of Africa
  • At each of the stop, Darwin had the opportunity to study the local plants and animals
  • Darwin found that nearby islands in the Galapagos had similar but nonidentical species of finches living on them,he noted that each finch species was well-suited for its environment and role
  • For example species that ate large seeds tended to have large, tough beaks, while those that ate insects had thin, sharp beaks
  • According to Darwin's idea, this pattern would make sense if the Galapagos Islands had long ago been populated by birds from the neighboring mainland
  • On each island, the finches might have gradually adapted to local conditions (over many generations and long periods of time)
  • This process could have led to the formation of one or more distinct species on each island
  • Darwin developed and refined a set of ideas that could explain the patterns he had observed during his voyage
  • In his book, On the Origin of Species, Darwin outlined his two key ideas: evolution and natural selection
  • Natural selection which also known as “survival of the fittest,” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits; this leads to evolutionary change
