Diatoms are microscopic. Diatoms range in size from about 2 microns to about 500 microns or equal to the width of a human hair.
Diatoms account for 23% of the primary productivity of the world, that's what they do!
What are a diatoms physical characteristics?
Diatoms are plantlike protists of the phylum Bacillariophyta.
How do invertebrates differ from each other?
Land and aquatic vertebrates are similar in that they both have a vertebral column. They are both either primary or secondary consumers as well. A difference is that vertebrates that live only in the water do not have fully developed hind legs.
How do amoebas get rid of excessive water?
it gets rid of its extra water by skirting it out when every it gets full or has to much water inside it
Is a paramecium heterotrophic?
Yes, Paramecium is heterotrophic.
It has no chlorophyll or other means of synthesizing organic matter, such as glucose, from inorganic compounds like carbon dioxide and water. So it cannot be autotrophic.
It must obtain organic compounds from other organisms, and is therefore heterotrophic.
Why are infections by fungi and protists usually more difficult to treat than bacterial infections?
Viral infections are harder to treat than bacterial infections because bacterial infections can be treated with antibiotics, while viruses cannot
Fungal infectons are difficult to treat because of the nature of fungi. They are phylogenetically very closely related to animals and have a very similar biochemical makeup to animals. In treating an internal fungal infection it is difficult to find a drug that kills the fungus and not the animal. Most fungi are killed by the immune system, and if it is impossible for the immune system to kill the fungus on its own, then the animal is likely to not survive.
Bacteria on the other hand are prokaryotic, making them very different from eukaryotic life (plants, animals, fungi, and protists). It is easy to target the bacteria cells as they are so biochemically different from our own. The only thing needed to do to kill a bacterium is to destroy the cell wall, which can be done using a number of drugs. Although it may be true that bacteria is easier to kill inside a human than fungus is, there are antibiotic resistant bacteria now.
How can you describe a mosquito?
The mosquitos are insects which make up the family Culicidae. They have a pair of scaled wings, a pair of halteres, a slender body, and long legs. The females of most mosquito species suck blood (hematophagy) from other animals, which has made them one of the most deadly disease vectors known to man, killing millions of people over thousands of years and continuing to kill millions per year by the spread of diseases.
Both male and female mosquitos are nectar feeders, but the female is also capable of haematophagy (drinking blood). Females do not require blood for survival, but they do need supplemental protein for the development and laying of their eggs. Prior to sucking the blood, they inject a mild painkiller, which numbs the host to the pain from the "bite" (Note: mosquitos do not actually bite). The Toxorhynchites species of mosquito never drinks blood. This genus includes the largest of the extant mosquitos, the larvae of which are predatory on the larvae of other mosquitos. These mosquito eaters have been used in the past as mosquito control agents, with varying success
In the Spanish language, the word Mosquito (little fly) dates back to about 1572. The word was adopted to replace the term "biting flies" to prevent confusion with the house fly. It is derived from the word fly (Latin musca, cf. Skt maksh) and is related to the Italian moschetta and the French moustique. Mosquitoes were originally called "les moucherons" or "les cousins" by French writers, "Stechmücken" or "Schnaken" by Germans, "mygg" and "mygga" by Scandinavians, and "κώνωψ" (konops) by the ancient Greeks. The Scandinavian word is related to the Modern Greek word "μύγα" (myga) for the housefly. The Icelandic "mý" mostly stands for biting midges or non-biting chironomids, as there are no mosquitos in Iceland. Aristotle referred to mosquitoes in 300 B.C. as "empis". == ==
What are similarities between the Paramecium and Amoeba?
*they are all animal like protists
*they can move on their own
*they feed on other animal like and plant like organisms
What are special features for protists?
Protists are simple microorganisms. They are unicellular or multicellular, but without specialized cells. They live in aquatic environments. they include fungi, plants, animals, bacteria, and archaea.
Where does the amoeba and the paramecium live?
Algae, dead animal matter, dead plant matter, and organisms smaller then they are!! Hope this helps :)
Which protists are hetertrophs?
Protozoans are heterotropic organisms.Algae are photosynthetic protists.
What structures provide locomotion in paramecium?
Paramecium contain cilia (hair like growth), all around their cell that helps them to move.
