Expert Solution

A protist is a eukaryotic organism. In historical classification algae and invertebrates are grouped in kingdom protista. The term Protoctista of biological kingdom includes certain multicellular organisms such as kelp, red algae and slime molds. Modern classification based on function and biological criteria certain brown, multicellular red and green algae are excluded. Most of the algae are considered to be protist .

Chlorella pyrenoidosa :A fresh water green algae belonging to genus Chlorella. Dioxin from the body is used as a chelatory agent in medicine.
Platymonas sp. : A genus of green algae. They are unicellular, biflagllated, colonial and inhabit fresh water environment.
Gymnodinium sp. : A genus of marine or fresh water dinoflagellate algae. Gymnodinium belong to red dinoflagellates.
Hydrodictyon sp. : It is a taxon of green algae of the family Hydrodictyaceae which is also known as water net. They inhabit inclean, eutrophic water.
Eudorina cylindrica : A paraphyletic genus in green algae, It is a protist having flagella and mainly seen as colonies of 16,32 or 64 individual cells.
Micrasterias abrupta : A unicellular green algae in kingdom plantae.
Agardhiella subulata : A red alge in the kingdom plantae inhabit marine environment.
Rhodymenia sp.: A genus of red algae .
Cypris sp.: An Arthropod in kingdom Animalia. Cypris are ostracods related to mussels and shrimps.
Philodina sp.: A bdelloid rotifer in the kingdom Animalia. These rotifiers are abundant in lichens and mosses where low abundance of water.
Dugesia sp.: They are platyhelminthes found in fresh water habitats.
Aiptasia sp. : It belongs to the genus of symbiotic cnidarian in the phylum of sea anemone

Invertebrates are animals which does not posses vertebral column. Cypris sp. and Aiptasia sp. are invertebrates.

1) Which of the following statements is true or false. a)Species that are smaller than their prey (host), live in or in association with their host, and either kill their host directly (by consuming it) or kill their host evolutionarily (by preventing it from reproducing) represent an extremely virulent form of parasitism (known as parasitic castrators, parasitoids, or brood parasites). This extremely virulent form of parasitism is most likely to evolve in situations where the host species is large, slow...

Order the following species from the one which binds lead (II) ions least strongly to the one which (at this pH) binds them most strongly and leaves the smallest equilibrium concentration of lead ions in solution: chloride ion, chromate ion, EDTA ion, water molecule. Please explain the logic behind the order in which these were placed. I initially went by solubility but it does not seem to quite fit what the question is asking. Thanks in advance.
