Thefish on a farm can be infected by parasites called sea lice, which are smallcrustaceans that feed on a fish's blood and skin, which may injure or even kill thefish.Jansen and colleagues (2012) analyzed sea lice infections on trout and salmon farms.Fish farms provided data on the numbers of sea lice found on their captive fish. Thescientists compared the number of sea lice with the "local farmed fish biomassdensity," which is a measure of population density that accounts for both the numberand biomass (or size) of fish on a farm. Other research has also found a relationshipbetween sea lice infestation and mortality.From this figure and information, how does density of fish on a farm affect thenumber of sea lice per fish? What type of factor is regulating the size of farmed fishpopulations and population growth?100200300400Local farmed fish biomass density(metric tons)3.2.Sea lice counts

A new medication has been found that can stop the spread of a disease significantly by a process that does not allow the virus to leave the infected person's body. Patients who do not take the medication have very high transmission rates. The Center for Disease Control and Prevention (CDC) randomly selected participants for a study and divided them into two groups. The first group received the medication and the second group did not. The CDC has concluded that the medication could halt the spread of the disease. Which statistical study did the CDC most likely use? a They most likely used a sample survey that asked patients who took the medication whether they came in contact with someone who had the disease. b They most likely used an observational study that observed patients, selected at random, to determine whether those patients who took the medication spread the disease to others. c They most likely used an experimental study under controlled circumstances on…
A scientis wants to determine whether a new cold medicine relives symptoms more effectively than the currently used medicine. Do you think its is possible to design a randomized experiment to study this question, or will an observational strudy be necessary?? Explain
Answer each question with proper justification. Suppose a pharmaceutical company has developed a new medicine to cure a disease. To see whether or not this medicine is effective in curing the disease, it will have to be tested on a group of humans. Suppose there are 100 persons who have this disease; 50 of them voluntarily decide to take this medicine, and the remaining 50 decide not to take it. The researcher then compares the cure rate for the two groups of patients. Is this an example of an observational study or a designed experiment?
Example: Three birds loved to eat beetles especially the green (female) and the brown (male). But their favorites are the green beetles. Generations later, green beetles have been selected and brown beetles have increased in number.- What do you think will happen if a disease was introduced and invaded the species living in an ecosystem?This is not aimed at the example, but you may use it as reference, thanks!

The following is an excerpt from a discussion of Principlism, which we have studied. (https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/principlism) Consider, for example, the question of what health professionals should do when they discover that a patient infected with the human immunodeficiency virus (HIV) is having unprotected sex with partners who are ignorant of his condition. First, respect for the patient's autonomy supports a policy of medical confidentiality, requiring health professionals not to reveal to others private information discovered in the course of caring for patients. According to this policy, health professionals should do nothing to warn the sexual partners of their HIV-positive patient, as doing so would violate his confidentiality. Second, if there is evidence that public disclosure of the patient's condition would harm him economically, socially, psychologically, or physically, the principle of nonmaleficence would also urge…
Scientists hypothesize that disrupting our ________ communities may increase our susceptibility to infectious diseases, predispose us to certain cancers, and contribute to conditions such as asthma and other allergies, irritable bowel syndrome, Crohn's disease, and autism.
You’ve been noticing that a local pond has developed a green scum that is getting thicker and thicker. When you look into the water, you see fewer fish and other animals than you used to, and you see fewer birds around the pond. Based on what you learned in this chapter, what is this process called? What are two possible causes. Explain in 10 sentences or more
You are a researcher researching Zika virus, a mosquito-borne pathogen. The number of cases of Zika have skyrocketed over the past few months and the weather service has recorded the data showing that this summer has been the wettest in the past 50 years. Using the scientific method, develop a sound hypothesis explaining the increase in disease cases and a method for testing this hypothesis.
