Ecology is relationship between different organisms in a ecosystem
The body recognizes after the body has been presented with or dealt with the pathogen before. the immune system defends against pathogens and the immune system then after recognizes the pathogen when the pathogen has been killed. the pathogen is recognized through the proteins presented on its surface. vaccinations contain pathogens but in small amounts in which the body can control and defend against, after the body has killed the pathogens it will later recognize it and defend better
The resting potential of the neuron would be reduced from
-70mV. This is because increasing K+ ions inside the cell reduced the electro
negativity of the inside of the cell in comparison to the outside. Therefore,
the reaching the potential to induce an impulse would be easier but then the
impulse would be weaker than normal.
Answer:
The categories of patterns of evolution are: <em>genetics/molecular biology, direct observation of evolutionary change, the fossil record, homology/anatomy, and biogeography</em>
Explanation:
- <u>Anatomy.</u> Also known as Homology, is the study of homologous structures of species with similar physical features, as proof of direct descent and ancestry.
- <u>Molecular biology and Genetics</u>. DNA and the genetic code reflects the shared ancestry of life, indicative of how species are related.
- <u>Fossil Records.</u> Fossils register the existence of pre-existing species which are related to present-day species.
- <u>Biogeography</u>. The geographic distribution of organisms on Earth, as well as their distinct features is an indicator of evolution and geological change.
- <u>Direct observation. </u>Organisms with short lifespan can be observed as evolutionary cases.
