Answer:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

Answer:
The correct answer will be-
1. Pupil
2. Retina.
Explanation:
Organisms are able to see the world around them thorugh the sense organs called the eyes.
The structure of eye contains various modified structure which include the membranes and the attached muscles.
When light enters the light through the dome-shaped structure called cornea which contains the convex lens converges the light and light enters the hole called pupil through which light enters and strikes or get focused on the retina present at the back of the eye.
The pupil is attached to the ciliary muscles which dilate and contracts in the response of the intensity of light as during high light intensity, the pupil constricts whereas during the low light intensity the pupil dilates to allow the maximum amount of light.
Thus, pupil and retina is the correct answer.
Wow that is a lot of reading. You should be wise and do it yourself. To much sorry .
Okay the answer is C. Adapted to high-oxygen levels.
Answer:
Explanation:
The evolutionary tree is composed of,
- Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches ⇒ Elephant species X, Y, Z
- Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor ⇒ The red spot in the graph shows the location o the most recent ancestor between species X and Y
- Root → This is the older common ancestor that all lineages share. The first one in the tree ⇒ The blue spot in the graph show the oldest common ancestor shared by the three species
Two or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
