Step by step
Solved in 2 steps
- In your own words, please answer the question. It is a fact that insects are widely distributed in any type of ecosystem. Some are vectors of causative agents of diseases and yet they can still survive although some don’t. If other animals have their immune system like man, what about the insects? In the context of circulation or the circulatory system, how do insects defend themselves from infection? Give 2 examples.If you had minimal resources to survive a disease related quarantine, as we’re currently experiencing, which class of invertebrates would be more beneficial and why? This can be demonstrated in any form.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
- New research suggests a link between some microbes that normally live in the body and seemingly unrelated major illnesses. The gum disease called periodontitis itself is not life-threatening, for instance, but it is a fairly good predictor for heart attacks. Bacteria that cause gum disease can trigger inflammation. Thinking back to your reading in Chapter 7, how do you suppose that this response also may be harmful to the heart?How would you classify the following organism? A flesh fly (Anolisomyia) whose larvae develop inside lizards and often kill their lizard hosts Predator Parasitoid ParasiteIs it more beneficial for Neodermata to have one host or two hosts? Neodermatahas two classes: class Trematoda and class Monogenea. Class Trematoda has the subclass Digenea, which has organisms that live through at least two different hosts. An example of this is Fasciola hepatica, the sheep's liver fluke. Class Monogenea has organisms that only need to live through one host. Is it better to have a simple or complex life cycle? Which lives longer? Has more energy? Does more damage or good?
- Add Numbers 1-9 in order of when the statement is found in the entire malaria life cycle. #1 is already placed. Mosquito bites infected human and becomes infected. The host experiences symptoms of fever and chills. Parasite travels to the liver. Parasite travels through the blood stream and attaches to the red blood cell. 1 Infected mosquito transfers parasite to human. Red blood cells bursts and infects other red blood cells. There is a depletion of oxygen to the body. Parasite reproduces in the liver cells. Parasite reproduces in the red blood cell.Which is a correct statement concerning the insect circulatory system? Question 18 options: A) Blood transports oxygen and nutrients to all the tissues B) Blood is always contained in a system of tubes called tracheae C) The circulating fluid bathes tissues directly D) There is no heart, or pump10) Which of the following statements about the response of hosts to parasitic infections is FALSE? Question 10 options: Grooming by mammals and birds is a defense against parasites. If a parasitic infection occurs, the body often responds with an inflammatory defense, releasing histamines. Some forms of defense against parasites are behavioral, such as deer avoiding deerflies by seeking dense, shaded areas. An antibody response is the first line of defense when a parasitic infection occurs. Plants cut off contact between fungal parasites and healthy tissue by forming cysts or scabs.
- A principle of biology is that living organisms interact withtheir environment. Such interactions include potentiallythreatening environmental factors such as pathogens. Distinguishbetween three types of pathogens that affect the health of animals.It appears that infection by Plasmodium is negative for Anopheles. We also showed in class that the mosquito immune system can be upregulated to limit or terminate Plasmodium infection of these mosquitoes. So why don’t we see natural selection to upregulate the mosquito’s immune system and get rid of that parasite? Best explanation. Upregulating the immune system comes at the cost of shortening life span and thus (most probably) reproductive success Having a Plasmodium infection is negative for the mosquito, but it protects against much worse pathogens Upregulation of the immune system in Plasmodium leads to more rapid development of Plasmodium, causing even greater problems for Anopheles Statement is wrong. This upregulation was done with genetic engineering in a lab. Alleles to do something like that do not exist in natureWhat is aposematic coloration? Choose All That Apply a type of physical defense mechanism a type of mullerian mimicry warning coloration in toxic organisms a type of chemical defense
