or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Baxter is very lethargic‚ has an increased heart rate‚ and when you pinch his skin the fold remains visible. The owner tells you that they knew something was wrong when‚ upon returning to the outdoor car park from a three hour shopping trip‚ they saw Baxter passed out on the back seat. The temperature in the car would have been very high and Baxter

Types of species 1. Endemic species Endemism is the ecological state of a species being unique to a defined geographic location‚ such as an island‚ nation‚ country or other defined zone‚ or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. they are only found in certain locations‚ they require special conservation efforts Animal examples: Lemurs of Madagascar‚ tortoises of the Galapagos‚ polar bears‚ koalas‚ kangaroos.

The Ted Talk video entitled “Animations of Unseeable Biology” describes the process of DNA replication. As the speaker Drew Berry explains‚ this process is repeatedly occurring and is performed mechanically. He provides us an animation of how a chromosome is replicated and split with the help of microtubules. Microtubules are straight tubes that are made up of proteins and it resides within a cell. This hollow tube allows the mitosis phase to occur. The copying of DNA is transported across the microtubules

Robert Brown is credited with the discovery of the cell nucleus. 4. Schleiden and Schwann’s contribution to biology was proposing that cells are the basic structural unit for plants and animals. 5. Before Virchow‚ one idea was that living things could arise from non-living and from dead matter‚ a process called ‘spontaneous generation’. 6. Person B is more

Advanced Cell Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First‚ since we know the viral RNA sequence and its targeting protein‚ we can investigate it in bioinformatics database‚ and can acquire some clues or hints about the target proteins. From the bioinformatics database‚ we might be able to find its structure‚ similarity with other proteins‚ functions‚ and binding domains. In other words
