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.

I am The red blood cell
Yuliya22 [10]

Red blood cells, also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.

this is about red blood cells but what are you asking

yarga [219]

Answer:

Yes, there is a need to assure the client that this is a normal reaction.

Explanation:

In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.  

Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.
