Organism a is the parent and b and c are siblings
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.
There are many different believes when it comes to this topic. Some people believe that there is no god and evolution did happen and then you have the opposite where some people believe evolution didn't happen and there is a god. But then there are some people I have come across who believe in both. Now there is a lot of evidence that can point to evolution actually happening but there is still many unanswered questions and gaps. In my personal opinion I think it is still too early to explain wether evolution happened, just because having spent studying this topic I realized there was a very important chunk of information missing. You may have heard that scientist have tried to connect apes with humans but they haven't quite fit in that puzzle piece. Personally I'm a christian but I am still open-minded to the idea of evolution. Hope this helps(;
Answer:
food sources
Explanation:
Because food sources varied from island to island, the finches with the best beak size and shape for the available food survived and reproduced better that those with beaks less suited to that particular island. Over time, the finches evolved into separate species.
Temporal bones are the bones of the skull which are most
associate with hearing and balance.
Skull is made up of many types of bones, temporal bones are
one of them. These bones are present at the base and sides of the skull. Temporal
bones consist of many parts, as these bones are present at the side of the head
so that’s why they are associated with hearing. They are also known as house the
structure of ear.
