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.
Properties of WBCs
Diapedesis:
WBCs can squeeze through the pores of blood vessels (even the
pore is much smaller than the cell size) by the process of
diapedesis.
Ameboid motion:
Once WBCs have entered the tissue spaces, they move through by
ameboid motion. They can move at least three times their own
length each minute.
Phagocytosis:
It's an essential process especially for the neutrophils and
monocytes. Selective structures can be ingested then digested via
this process. Phagocytes have proteolytic enzymes, lipases and
other agents (killer system) that kill the foreign materials.
Chemotaxis:
Different chemical substances can attract WBCs and make it move
toward the site of the chemicals. It depends on the concentration
gradient of these secreted substances.

What are three features that characterize most protists?
Characteristics of Protists
Protista = the very first
What is the structure of filamentous algae?
Filamentous algae consists of long, thread-like strands made up of multiple cells joined end-to-end. These strands can be branched or unbranched, forming a mat-like structure. The cells of filamentous algae contain chlorophyll for photosynthesis and can reproduce by fragmentation or forming spores.
Diatomic means consisting of two atoms. In chemistry, diatomic molecules are molecules composed of only two atoms of the same or different chemical elements bonded together. Examples include oxygen (O2) and hydrogen (H2).
Which is a diatomic element iodine mercury arsenic or tungsten?
No. Tungsten is a metal and so exists as individual atoms.
There are 7 diatomic elements: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine. All can be found on the right side of the periodic table, with the exception of hydrogen, which is in the top left corner.
What diseases can amoeba cause?
Amoebas like Entamoeba histolytica can cause amoebic dysentery, a type of severe diarrhea with blood and mucus. Acanthamoeba and Naegleria fowleri can cause rare but serious infections of the brain and central nervous system (acanthamoeba keratitis and primary amoebic meningoencephalitis, respectively).
Why is a contractile vacuole important to paramecium?
Water is constantly coming down it's concentrations gradient and osmotically entering the paramecium's cell. The cell would soon burst if there were not a way to offload much of this water, so contractile vacuoles do this job for the paramecium.
What is a true of all protists?
All protists are eukaryotic organisms, meaning they have cells with a nucleus and membrane-bound organelles. They are primarily unicellular, although some can form multicellular structures. Protists exhibit diverse modes of nutrition, including photosynthesis, absorption, and ingestion, making them a highly varied group. Additionally, they can be found in a wide range of habitats, often in moist or aquatic environments.
Yes, Protozoa require moist environment; most species live world wide in ponds, lakes, streams, and oceans, where they are critical members of the plankton- free living, drifting organism that form the basis of aquatic food chains.
How do large food particles exit an amoeba?
Amoeba ingests food by a process known as phagocytosis. The amoeba modifies its cytoskeleton to 'wrap around' the food particle with its membranes. The membrane then fuses, trapping the food particle in a vacuole inside the cell. The vacuole is then fused with a lysosome and the lysosomal enzymes will break down the food particle.
In a unicellular organism like Paramecium, food is stored and digested in a structure called a food vacuole. Once the food vacuole is formed, enzymes are released to break down the food particles for absorption and energy production.
