Describe the life cycle of the human hookworm? How was john D. Rockfeller and southern US commerce involved in this story?how far away from a pile of poop can a hookworm crawl before dying? How did Rockfeller's medical investigators eradicate the hookworm problem, as well as many excrment- related parasitic disease?
In the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions:
Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments.
Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments.
Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments.
Non-filamentous cyanobacteria generally produce spores…

- 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?arrow_forward1) Make a graphic/visual organizer of the four supergroups of Protists and the major groups of protists. 2) The graphic organizer must include all the following major groups.

A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with hamster droppings and don’t wash their hands before eating. The organism exhibits active, motile morphological forms at other stages of its life cycle. Sexual reproduction (fusion of haploid gametes) occurs in the hamsters; only asexual reproduction occurs in humans. It has a nucleus, but does NOT have a cell wall.
