Imagine that someone places their hand on a hot stove. Immediately, and without realizing it, the person moves their hand away quickly. How do you think the body gathers information about the hot stove and translates that into a large muscle movement so quickly? Can you identify...
Compare and contrast between Fast-twitch muscle fibers and Slow-twitch muscle fibers and discuss which you think is more important for maintaining homeostasis...
Do you think that cloning organs or embryonic treatments for diseases will eventually be as commonplace as in vitro fertilization are now? What might influence your own decision to support these technologies or those that research them? Defend your responses and if you could link...
In a small organism, cells are close to one another making communication relatively simple. Discuss the evolution of cell signaling as an organism becomes increasingly multicellular. Can you Compare and contrast cell signaling in plants and animals?...
Describe a bottleneck situation that could take place in a forest ecosystem and how it would change the allele frequencies of the population. (4 points) Forest fires can cause a decline in species population size. A genetic bottleneck in population genetics is a sharp decline in...
Why is it possible for the complement pathway to destroy the pathogen while not harming the host tissues even if activated complement components land on host tissue?...
In a small organism, cells are close to one another making communication relatively simple. Discuss the evolution of cell signaling as an organism becomes increasingly multicellular. Can you compare and contrast cell signaling in plants and animals?...
Compare and contrast the nervous and endocrine systems. For comparison, include general purpose, general mode of action and physical connections. For contrast, include component of body that produces or sends the signal, type of chemical signal between cells, the physical area of influence of that...
Discuss why there would be a need for all four Ecological Interactions to occur within a sustainable ecosystem? HINT to improve your grade: Each Ecological "Interaction" falls under either a competitive or symbiotic "category." So, when answering Part a of this week's Discussion Topic, please make...
Cigarette smoking is a major risk factor in the development of non-small cell lung cancers (NSCLC), which account for 80% of lung cancers. This cancer has a poor prognosis and is resistant to chemotherapy. To understand if nicotine affects this resistance, lung cancer cell lines...
