Each species of Galápagos Finch Has a beak suited for eating a particular type of food. How are darling have explained this patt
Lena [83]
<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

Why is it very unlikely for a frameshift mutation to be a silent mutation?
never [62]
When a frameshift mutation occurs, the string of DNA will be glued together. When this DNA is going to be part of a process, such as a transcription, whatever is causing the process is unaware of the mutation actually having happened.

I have a simple question about external variables. If I'm doing an egg drop experiment, and my teacher "chucks" it off of the ro
otez555 [7]

Ok, a few things here:

This is an egg drop experiment, so I'm assuming you are testing out different ways of protecting the egg.

The independent variable is what you want to change: This would be the type of protection you have on the egg

The dependent variable is what would be effected by the changes in the independent variable: which would be something like the integrity of the egg after it hits the ground. You'd have to measure that somehow.

There are two types of controlled variables: <em>Internal and External.</em>

Internal variables are within the scope of the experiment and can be controlled, whereas external variables are outside the scope of the experiment and we have no control over them.

Internal:

- Height of the drop

- Type of egg

- Person dropping

- How the egg is dropped

- Surface being dropped on to

External:

- The person designated to drop the egg is sick

- You run out of eggs to drop

- Somebody loses all the planning for the experiment

- The weather forces you to do the experiment inside versus outside

- The wind blows your egg off course, leading to it hitting the ground at an angle

So, the way your teacher "chucks" the eggs off the roof should be a controlled internal variable. The action should be done as consistently as possible to avoid an uncontrolled variable.
