Question

1. list name three traits protists have in common.
2. identify what kind of reproduction results in offspring that are different from their parents? what kind of reproduction results in offspring that are identical to their parents?
3. apply concepts why are mosquito control programs used to prevent the spread of malaria?
4. list name four ways protists obtain food.
5. explain some scientists think kingdom protista should be divided into several kingdoms. what do you think is the reason for this?

Explanation:

1. Protists are eukaryotic, mostly unicellular, and can live in aquatic environments.
2. Sexual reproduction results in genetically - different offspring due to genetic recombination. Asexual reproduction results in identical offspring as it involves only one parent and no genetic mixing.
3. Mosquitoes are vectors for the malaria - causing Plasmodium parasite. Controlling mosquitoes reduces the number of parasite carriers, thus preventing malaria spread.
4. Protists can be autotrophic (photosynthesis), heterotrophic (ingest food particles), saprophytic (absorb nutrients from dead organic matter), and parasitic (obtain nutrients from a living host).
5. Protists are a very diverse group with a wide range of characteristics, cell structures, and modes of nutrition. Grouping them into several kingdoms would better reflect their evolutionary and biological diversity.

Answer:

1. Eukaryotic, mostly unicellular, aquatic - living.
2. Sexual reproduction results in different offspring; asexual reproduction results in identical offspring.
3. Mosquitoes are vectors for the malaria - causing parasite; controlling them reduces parasite spread.
4. Photosynthesis, ingestion of food particles, absorption from dead organic matter, parasitism.
5. Due to their high diversity in characteristics, cell structures, and nutrition modes.
