I believe its is because the fossils of these animals looked like living species and they had a connection to the modern. A fossil is any preserved evidence of life from a past geological age, such as the impressions and remains of organisms embedded in stratified rocks. Fossils are created when organisms die, are in cased in dirt and rock, and are slowly replaced by minerals over time.
Hybridoma cells resulting from the fusion of B lymphocytes and myeloma cells produce specific monoclonal antibodies.
A popular technique for creating monoclonal antibodies is hybridoma technology. After immunising mice with a particular antigen, antibody-producing B lymphocytes are extracted from the animals and united with immortal myeloma cell lines to create hybrid cells, also known as hybridoma cell lines.
<h3>What is Immune system ?</h3>
A vast network of organs, white blood cells, proteins (antibodies), and chemicals make up your immune system.
- Together, these components of your body's defence system guard you against external invaders (bacteria, viruses, parasites, and fungus) that can lead to illness, disease, and infection.
- A weakened immune system can momentarily be brought on by treatments like anticancer therapies and radiation therapy, despite the fact that it is primarily brought on by certain illnesses, starvation, and specific genetic problems.

Hello there,
<span>Euglenas are protists, so they are eukaryotes.
</span>Euglena is classified as eukaryotic organism because some of its cell organelles are clearly defined, that is, they are surrounded by membranes.
