Answer:
The answer is the placement of the eyes.
Explanation:
Developing depth perception through evolution for reasons such as hunting and movement was crucial in the survival of the species and it was made possible by the change in the location of the eyes to the front of the head. Because of the location of the human eyes and the distance of approximately 6 centimeters between them, they perceive slightly different images of the world and this also helps with the depth perception.
I hope this answer helps.
Answer:
In the cardinals, if the females start using a different criterion than the color of the feather when they choose couple, most likely to happen is that decreased variation in the shades of red because no form of the trait is advantageous.
Explanation:
Options for this question are:
- <em>Increased variation in the shades of red because the selection pressure has been relieved.</em>
- <em>Increased variation in the shades of red because the cardinals try different ways to impress the females.</em>
- <em>Decreased variation in the shades of red because no form of the trait is advantageous.</em>
- <em>Decreased variation in the shades of red because the only reason for variation was selection pressure.</em>
In the context of natural selection, male cardinals court females using the coloring of their feathers as a form of sexual selection. This means that the shades of red in the feathers are a selection criterion in these birds, and the more visible shades represent an advantage.
But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate. Instead, the trait that would determine sexual selection would be the one that experiences an increase in its variation<em>.</em>

Answer:
Unlike prokaryotes, eukaryotic cells compartmentalize various metabolic processes inside membrane-bound organelles. For example, the breakdown of certain food molecules to provide energy takes place in the mitochondrion, and photosynthesis takes place in a chloroplast.
