I think so because most people have a decent life although they may complain about some things in it.
I think none of the above...
<h3><u>Answer;</u></h3>
Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.
<h3><u>Explanation;</u></h3>
- Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
- Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.
Answer:
If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.
Explanation:
This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.
The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
Explanation:
Energy and homeostasis are related in living organisms because we need energy in order for our systems to stay balanced and work to keep our bodies in
All organisms must intake sufficient energy on a sufficiently regular basis to fulfill the minimal requirements of homeostasis and allowing for input energy gaps to be covered by natural energy storage mechanisms, which storage can be filled during sufficiently regular periods of excess input energy.
Cells are homeostatic; viruses are not
