Hospitals are finding the importance of developing strategies to become a high reliability organization (HRO). Why would this be important in healthcare and share at least 1 strategy that should be used to develop this type of an organization?

describe four animals’ mating strategies in your own words.

1a. what generates proton gradient? where is it generates and how does that limit amount of gradient possible?

1b. What is oxygen used for during metabolism, and what happens if it is absent?

1c. What molecule increases in the cell when oxygen is absent, and what cellular process related to cell death can this trigger? How is this mechanism an anti-cancer mechanism?

1d. In multicellularity, what problem arises in reproduction by only a subset of the aggregate cells? Does this same problem arise in clonal forms of multicellular organisms?

1e. What enzymes are used in cell signaling in metazoa?

1. How does an electrical impulse from a nerve lead to muscle contraction?
2. How does skeletal muscle contract and generate force?
3. How does muscle twitch, summation, and tetanus affect the strength and duration of muscle contraction?
4. What are the different types of skeletal muscle contractions? Explain the difference?

Own Words Please.

Carbon monoxide poisoning often has fatal results. When an individual is exposed to large amounts of carbon monoxide, it essentially prevents oxygen from being delivered to electron transport chains. Based on your understanding of the electron transport chain, what specific problems would this cause? Why would the individual ultimately die?

Explain the importance of glycolipids in the plasma membrane, identify where they are produced inside the cell, and describe the mechanism by which they are transported to the plasma membrane and presented to the extracellular environment. Draw a diagram to support your answer.

A red blood cell has a disk diameter of 0.6 micrometers and an intracellular isotonic osmolarity of 290mOsmol/l at a temperature of 293 kelvin. The hydraulic permeability of the red blood cell is 2.4 micrometer atm^-1min^-1 with a b inactive fraction intercept of 0.2. Calculate the normalized cell volume and plot it against osmolarity variations between 50mOsm to 850mOsm. Plot another graph that represents cell volume variations against time when the extracellular isotonic osmolarity varies from 290mOsmol/l to 990mOsm/l.

Scientists were successful in creating Dolly the sheep using the nucleus isolated from a differentiated cell from an adult mammary gland. They transferred this nucleus to an enucleated egg and activated the egg to start development. Thus, the adult mammary gland nucleus could replace the nucleus created in the 1 cell zygote from the fusion of the egg and sperm genetic material. Wow! It's amazing that this works!

1) Describe in your own words how the success of reproductive cloning is able to demonstrate "genomic equivalence".

2) BUT....While this technique was successful in creating Dolly (and in a wide array of other species), it has a notoriously low success rate. Ignoring all of the technical reasons why this could fail (meaning ignoring all of the "scientist user error"), explain how the contents of the nucleus can contain the same genetic sequence but still not be functionally equivalent to the 1 cell zygote nucleus. What might be different between a mature nucleus and a zygote nucleus that results in the low success rate?

need new and unique answers, please. (Use your own words, don't copy and paste), Please Use your keyboard (Don't use handwriting) Thank you..

PHC 231

1.   Discuss Central Line-Associated Bloodstream Infection (CLABI)
"or" Ventilator-Associated Pneumonia (VAP) outbreak in long-term acute care hospital
settings. Address the following in your report:
a)   Characterize the epidemiology and microbiology
b)   Describe the agent, and identify the host and the environment that is favorable
for the infection.
c)   Discuss how the infections spread and the types of prevention and
control measures
d)   Identify a population and develop a hypothesis about possible causes
in a testable format with standard statistical notation (the null and the alternative)
e)   Explain how you would choose controls to test this hypothesis?

Why is the rapid initial growth rate of the hypocotyl-root axis important to seedlings? Contrast this with the epigeal type.  (hypogeal or cryptocotylar type of germination)

RNAi is used to functionally inactivate genes in cells and whole organisms like C. elegans. Describe the basics of how you would knock down the expression of a gene required for muscle formation in C. elegans and what method could you use to confirm that your results were specifically attributed to the RNAi?
