The right option is D. vector-borne
Diseases carried from person to person through other hosts, such as animals or insects, are known as vector- borne diseases.
Vector-borne diseases are infectious diseases transmitted between humans or from animals to humans through the bite of infected hosts such as animals or insects. Most of these hosts are arthropod vectors which are bloodsucking insects such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Examples of vector-borne diseases include West Nile fever which is transmitted through the bite of an infected Culex mosquito, Leishmaniasis which is transmitted through the bite of an infected female sandfly and Tick-borne encephalitis (TBE) which is transmitted by ticks.
Fishes and bottom dwelling worms cope with the fluctuating salinity within estuaries over the tidal cycle with the use of transport system such as active and passive transport.
<h3>How active and passive transport system are used?</h3>
In salty water, fish and other marine organisms used active transport in which energy is used to remove salts from the body of these marine organisms because excess salts are harmful for them.
So we can conclude that Fishes use transport system such as active and passive transport to cope with the fluctuation of salt concentration.

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.
<h3>What is Protozoa?</h3>
- Protozoa is a group of single celled, non- prokaryotic organisms.
- These may either be free living or parasitic in nature.
- These are heterotrophs and reproduce asexually by binary fission.
- The Protozoa consists of many unrelated or loosely related organisms.
- They are divided into four major groups: Sarcodina, Flagellates, Ciliates and Sporozoans..
- Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
- Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
- The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

Answer:
Blood cells are produced in the bone marrow of the body more specifically they become blood cells from first being stem cells which then divide until they reach a mature red blood cell stage. ( or other types of cells, stem cells are like the blank template for either red blood cells, white blood cells, or platelettes.)
Explanation:
Answer:
A. stratified squamous epithelium; absorption
Explanation:
Stratified squamous epithelium are composed of multiple layers of cells which rest on a basement membrane. Superficial layers are made of squamous cells and underlying layers can also be made of cuboidal or columnar cells.
Stratified squamous epithelium is generally present in area where there is frequent physical or chemical abrasion. It protects the underlying structures from the stress. Hence, it is found wherever the body comes in contact with the outer environment like skin, digestive system and respiratory system. It also prevents water loss and desiccation.
