Mental health is worsening. Even before the Covid-19 pandemic, the prevalence of psychological disorders and suicidal ideations among adults in the United States was increasing. More youth and young adults, of all races and ethnicities, are struggling with their mental health. What factors do you think are contributing to this increase? Why?
Even though genetically engineered mosquitoes might be developed that do not allow the reproduction of malaria protozoa, these mosquitoes would have little, if any, immediate effect on the spread of the disease. Why should this be so? What would have to happen for these mosquitoes to significantly affect the spread of malaria?
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

- Malaria Where did the disease originate? What impact did it have on the individuals living in the effected areas? How was the disease spread? How did individuals combat the disease? What reforms were initiated after the event? Your research must contain one location in the U.S. or Colonial America that experienced an outbreak.arrow_forwardConsidering the solutions discussed in the lecture, in your opinion, what could have been done to stop the extermination of the thylacine? Can you think of another predator today that is being exterminated as a result of man's fear and ignorance? hint: they are an American species just recently introduced to the Northern Rocky Mountains. Do a google search and write about this current issue. Who? Where? Why?arrow_forwardYou are trying to develop a new anti-termite chemical that will not harm environmentally beneficial insects. Because termites are adapted to eat only wood, they will starve if they cannot digest this food source. Termites have two symbiotic partners: the protozoan Trichonympha collaris and the bacteria it harbors that actually produce the enzyme that digests the wood. Knowing this, how might you prevent termite infestations without targeting the termites directly?arrow_forward
- Three methods have been used to try to eliminate malaria. One is to eliminate the mosquito vectors of the parasite, a second is to kill the parasites after they have entered the human body, and the third is to develop a vaccine against the parasite, allowing the human immune system to provide protection from the disease. Which do you suppose is the most promising in the long run? Why? Think about both the biology of the disease and the efficacy of carrying out each of the methods on a large scale .arrow_forwardAssuming you have been posted to a community where malaria is very endemic. There is a high rate of absenteeism among your students due to incidents of malaria. As part of your community engagement explain how you would educate on malaria prevention taking the following into consideration:a) Name of the vector and the species of the parasite that cause the diseases in Africa; b) Two chemical and two biological ways of reducing the population of mosquitoes; c) Two in-house measures to prevent mosquitoes bite;d) The stages in the life cycle of the mosquito;e) The names of three African countries that participated in the trial of malarial vaccine.arrow_forwardThe insecticide DDT has been widely used to control the mosquitoes that carry malaria. How would you explain the fact that many mosquito populations are now resistant to DDT?arrow_forward

(b) What species of freshwater snail is its intermediate host?arrow_forwardA prion is one of the agents of disease in animals like a viroid. True or false?arrow_forwardCompare and contrast the lifecycles of northern black legged ticks to southern black legged ticks. What difference between these two variants makes the transmission of Borrellia burgdorferi lower in the south?arrow_forward
- In 1971, Alfred Knudson noticed that children like Kay, who have retinoblastoma in both eyes (bilateral), presented at earlier ages than those who had unilateral disease. To explain these different disease kinetics, he proposed the “two-hit hypothesis.” What does this hypothesis propose?arrow_forwardAn orchid species has flowers that resemble and smell like female bumblebees. The flower attracts male bumblebees, which attempt to mate with the flower. They get a package of pollen attached to their body, which they then deliver to another orchid flower of the same species. Which of the following statements about this is correct? a. this is an example of mullerian mimicry b. this is an example of batesian mimicry c. this appears to be a different type of mimicary rhat does not fit either mullerian or batesian model d. no answer text providedarrow_forwardFlies (the Order Diptera) contain the largest number of families that have evolved to blood feed and are responsible for transmitting a large fraction of vector-borne diseases. Can you think of reasons why the Diptera may have successfully utilized this life history and function as such efficient vectors?arrow_forward
