They intersect and cross each other
It suggests that the bone will have equal strength in all directions.
Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.
<h3>How have organisms evolved?</h3>
Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:
- The appearance of more complex organisms, which is the result of natural selection.
- The diversification of organisms.
- The extinction or disappearance of species.
This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.
<h3>Dinosaurs and chickens: </h3>
According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.
This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.
<h3>The megalodon and the great white shark:</h3>
These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
