Use the same article to answer the following question. Strongest Muscle Explain why the external eye muscle can be considered the muscle with the greatest dynamic strength.
Answers
The external eye muscle, also known as the lateral rectus muscle, can be considered the muscle with the greatest dynamic strength because it is responsible for the rapid and precise movements of the eye.
The external eye muscle is specifically designed to control the movement of the eye horizontally, allowing us to look sideways. This muscle is relatively small compared to other muscles in the body but has an exceptional capacity for dynamic strength. It is composed of fast-twitch muscle fibers, which are optimized for rapid contractions and movements. These fibers enable the eye to move quickly and accurately, allowing us to track moving objects and shift our gaze rapidly. The dynamic strength of the external eye muscle is essential for our vision and eye coordination.

Read the following and then answer the questions: Jimena was quietly enjoying her lunch when an unexpected knock on the door startled her. She found two people in suits standing on her front porch. They explained they were medical scientists from Columbia University in New York, and they were visiting her to talk about some old blood samples from a transfusion she had back in the 1970s. They showed Jimena a consent form that she had signed. It had allowed scientists to store and study her blood to help advance their medical knowledge. Now she was worried. Did she have some terrible disease? She invited them in and sat down in case the news was bad. The researchers explained that they were part of a team that searches for viruses in old blood transfusion samples. Their work was aimed at finding new transfusion-transmissible viruses that ought to be screened for in the donated blood supply to further protect patients. They were looking at samples from the 1970s because, unlike today, the only virus screened for back then was Hepatitis B. These lightly screened samples might lead to discovery of previously unrecognized viruses. Sadly, lack of broader screening for bloodborne viruses meant that thousands of people were infected with Hepatitis C and human immunodeficiency virus (HIV) by way of contaminated blood transfusions during the 1970s and 1980s. People with hemophilia, a blood-clotting disorder, had an unusually high prevalence of Hepatitis C virus and HIV. This is because managing hemophilia in the 1970s and 1980s often involved administering clotting factors derived from human blood. Before the stricter screening went into effect, at least 6,000 hemophiliacs in the United States are believed to have contracted Hepatitis C from blood transfusions. Of course, hemophiliacs were not the only ones who suffered: Anyone who got a transfusion for any reason at that time was at high risk for exposure to these viruses. In 1976, during her last trimester of pregnancy, Jimena had developed severe anemia. She remembered receiving a blood transfusion a few weeks before she delivered her son, Jose. The transfusion was done to ensure that her blood levels could support both her and her child during delivery. She knew this must have been the reason the doctors were visiting her now. She asked them if they were here to tell her she had HIV or hepatitis––she had been feeling very tired lately, and wondered if this was the cause. The doctors hastened to explain that the blood she received was not infected with Hepatitis C or HIV. But they had found something else: a new virus never seen before in humans. They examined the medical records of all the people who had received blood with this virus, and it did not seem to cause disease. However, they wanted to investigate more. They were here to get a more detailed medical history from Jimena, along with a new blood sample. They also wanted to reach out to Jose, Jimena’s son, and see if he’d be willing to take part in the study, too. Jimena’s eyes became moist as she explained that Jose had died of cancer eight years ago. The doctors expressed their sympathy, but pressed Jimena for the type of cancer he had developed. She said it was liver cancer. "Are you sure we didn’t catch hepatitis C from the transfusion?" she asked the researchers. "I know that can cause liver cancer, right?" "Yes, it can," they replied.
1. How could old samples of donate blood be screened to search for new viruses?
3. How could researchers isolate and grow a particular virus from the Jimenas blood?
Answers
The researchers could isolate and grow a particular virus from Jimena's blood through the following procedure: The process of isolating and growing a particular virus from Jimena's blood is called virus cultivation.
Researchers begin by collecting a blood sample and treating it with a substance that ruptures the host cells while leaving the viral particles intact. After that, they transfer the suspension to a suitable host cell and incubate it. The host cell is used to propagate the virus. If the virus reproduces, it is allowed to infect the host cells. Then the infected cells are checked regularly to see how the virus is doing in the host cell. This enables the researchers to research the virus and take measures to protect people from being infected by it.
Researchers can isolate and grow a particular virus from Jimena's blood by following several steps. First, they would collect a blood sample from Jimena. Next, they would separate the blood components, such as plasma and red and white blood cells, to identify the presence of the virus. Once they have located the virus, they would extract it from the blood sample.
To grow the virus, researchers would then introduce it into a suitable cell culture or host organism, which provides the necessary environment for the virus to reproduce. They would monitor the growth of the virus and collect new viral particles as they are produced. Throughout this process, researchers would ensure the cell culture or host organism is kept under controlled conditions, such as temperature and humidity, to optimize viral replication.

What was the experimental variable we tested in the lodine Clock Reaction?
Answers
Answer:Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while others occur over minutes, hours, or n over several years. What are the controlling in predicting if a reaction will take place and the speed at which it will? Thermodynamics can answer the question, "Will the reaction take place?" Once the reaction is capable of proceeding kinetics can answer the other question, "How fast You will study the rate of the reduction of potassium persulfate, KoS Os, with sodium iodide, Nal. The net ionic equation for the reaction is eve The rate law for this reaction is in the form of And you will need to determine the reaction orders a and b, as well as the rate constant, k. Keep in mind that exponents can not be determined by jus looking at the chemical equation the reaction will take place? The rate of a reaction is defined as the increase in molar concentration of product of a reaction per unit time or the decrease in molar concentration of reectant per unit time. The usual unit for the rate is moles per liter per sec (mol/L s or M/s). Experimentally, it has been found that a reaction rate depends on the concentrations of the reactants. Usually a higher reactant concentration increases chance of collision among the reactants per unit time causing a faster reaction rate. An equation describing the relationship between the reaction rate and the concentration of the reactants You will need a way to determine how much of the reactants were spent over the given time period. Preferably, the concentrations of the reactants should not change too much; therefore the reaction rate can be represented by the initial concentrations of reactants (the initial-rate method). In this experiment, we will couple another reaction that consumes the product, 12 very quickly. The new reaction is the reduction of is called a rate law. For the elementary reaction Note that l2, which was produced in reaction (1) is consumed as fast as it is produced by reaction (2) to regenerate two l. i.e. [门is kept constant. By keeping [S203-9 much smaller than the initial concentration of S,0, we can assure [S20,1 is also kept nearly constant when S203 is completely consumed. At this point, the 12 is no longer eliminated by the reaction and starts to accumulate. This point is signaled by sudden appearance of the dark color from the interaction of l2 with starch indicator. We can measure the time elapsed till the color appears Rate k [AIB] The proportionality constant, k, is called the ate constant in the relationship between the rate nd concentrations. The rate constant has a fixed alue as long as the reaction temperature is held nstant. The exponents, a and b, are called the action order, and are frequently, but not always, egers. More importantly, they must be termined experimentally In this experiment you will determine the rate an iodine clock reaction, and study the effects of perature and a catalyst to the reaction rate ugh there are several versions of an iodine k reaction, all of them share a common feature: completion of the reaction is signaled by the en appearance of a dark purple color. This is characteristic of the interaction between cular iodine and starch. When the reaction is ed out correctly, this color will appear so According to the reaction stoichiometries of reactions (1) and (2), two molecules of S203 are required to counteract the consumption of one molecule of S20a2. Since S2032 would have been completely consumed when the dark purple color appeared, the Δ[SO ] should be % of the initial concentration of S203 15-08-2] = ½ initial [S,03-21
What happens to the pressure of a gas if the volume of gas is
increased at a constant temperature?
Answers
Answer: If the volume of a gas is increased at a constant temperature, the pressure of the gas decreases.
Explanation:
The relation between variation in volume and variation in pressure of a gas at a constant temperature is given by Boyle's Law which states that: The product of pressure and volume of a mass of a contained gas is constant at a constant temperature.
That is,
Pressure (P) x Volume (V) = constant (k)
[when the temperature (T) is constant; k ≠ 0.]
Or, P = \(\frac{k}{V}\)
That is, pressure varies inversely with volume or an increase in volume at a constant temperature causes a decrease in the pressure of the gas.
Detailed answer:
Gas molecules are always in random motion, and the pressure of a gas is defined as the pressure exerted by these moving gas molecules on the walls of the container as they undergo collisions with the walls of the container. The volume of a gas is defined as the three-dimensional space occupied by all the gas molecules in the container at a particular temperature and pressure. Thus, when the volume increases keeping the temperature constant (thus no change in kinetic energy of the molecules occurs due to temperature), the molecules get more space to move around. Thus the pressure exerted by the molecules on the walls of the container decreases.Scientific instruments have shown that shock waves from earthquakes move long distances.
