Explanation:
Isolated on its own, bloodplasma is a light yellow liquid, similar to the color of straw. Along with water,plasma carries salts and enzymes. The primary purpose of plasma is to transport nutrients, hormones, and proteins to the parts of the body that need it.
Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.

Answer:
The correct option is D. analogous
Explanation:
We speak of an analogy when one structure is similar to another or has the same function, but whose embryonic development and its origin or ancestor is not common, they are different, in other words, they are analogous structures if they fulfill functions or acquire similar characteristics starting from the same medium, without requiring them to have the same evolutionary origin (they may or may not be similar structurally and embryologically).
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.
The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.
