- Which of the following correctly matches the protist to the mode of nutrition? Chara- Autotrophy, Euglena - Mixotrophy, Amoeba - Heterotrophy Chara - Heterotrophy, Euglena - Mixotrophy, Amoeba - Heterotropy Chara - Mixotrophy, Euglena- Heterotrophy, Amoeba - Autotrophy They all are capable of HeterotrophyWhich parasitic protist evades the host immune system by altering its surface proteins with each generation? a. Paramecium caudatum b. Trypanosoma brucci c. Plasmodium falciparum d. Phytophthora infrstans3) Did the planaria exhibit rheotaxis? yes If so, was it positive or negative?Negative 4) How would this behavior be beneficial for planaria? 5) Did the planaria exhibit chemotaxis? es If so, was it positive or negative? ositve 6) How would this behavior be beneficial for planaria? 7) Did the planaria exhibit geotropism?Ues If so, was it positive or negative? _Possive 8) How would this behavior be beneficial for planaria?
- A) Protist diseases can be hard to treat because Group of answer choices some use brown or red pigments, rather than green pigments, for photosynthesis they have prokaryotic cells anti-protist medicines have too much selective toxicity they are heterotrophic they have evolved defenses that make them invisible to the immune system B) A plant without vascular tissues will likely be Group of answer choices small and/or flat found primarily in dry habitats, such as deserts tall unable to photosynthesize unable to reproduce sexuallywrite an article on Cryptosporidium a pathogenic eukaryote parasite. What is the natural habitat for this organism? (water, soil, humans, plants, etc.) What clinical significance does this organism have for humans? (What disease/infections does it cause in humans?) What is the mode of transmission to humans? (How do you get an infection with this organism?) What is the worldwide geographic distribution for this organism? (Where is it found, where have there been reported cases or outbreaks lately?)What is a lichen? Why is this considered an example of a parasite-host relationship? Why might you also consider it a mutualistic interaction?
- Is 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?Why have molecular biologists sequenced the genomes of severalparasitic protists?Many biologists consider a lichen an example of controlled parasitism. In this view, which component is the likely parasite, and which is the likely host?
