Smatra se da višećelijske životinje vode poreklo od:
Correct Answer
D. Protista sa bičevima
Explanation
The correct answer is Protista sa bičevima. This is because protists with flagella are believed to be the ancestors of multicellular animals. These protists have whip-like structures called flagella that help them move and navigate through their environment. Over time, some of these protists evolved into multicellular organisms, eventually giving rise to the diverse range of multicellular animals we see today.

Od ponuđenih osobina izdvoj one koje se odnose na sunđere:
Correct Answer(s)
B. Filtracioni način ishrane
C. Na telu imaju veliki broj malih otvora (pora)
E. Imaju ćelije sa bičem i kragom
F. Razmnožavaju se pupljenjem
Explanation
Sponges are characterized by their filtration feeding method, as they filter small particles from the water to obtain nutrients. They also have a large number of small openings called pores on their body, which allow water to flow through for filtration. Sponges possess cells with flagella and collar, which are used for capturing food particles. Additionally, sponges reproduce through a process called budding, where new individuals grow as outgrowths from the parent sponge.

Od ponuđenih pojmova izdvoj one koji se odnose na pljosnate crve:
Correct Answer(s)
A. Dvobočna simetrija tela
B. Troslojni organizmi
D. Vrpčast nervni sistem
E. Dvopolni organizmi (hermafroditi)
Explanation
The correct answer includes terms that are related to flatworms. Flatworms exhibit bilateral symmetry, meaning their bodies can be divided into two equal halves. They are also triploblastic organisms, which means they have three germ layers during embryonic development. Flatworms have a ribbon-like nervous system called the tapeworm nervous system. Additionally, they are hermaphroditic, meaning they possess both male and female reproductive organs. Therefore, the terms "Dvobočna simetrija tela" (bilateral symmetry), "Troslojni organizmi" (triploblastic organisms), "Vrpčast nervni sistem" (tapeworm nervous system), and "Dvopolni organizmi (hermafroditi)" (hermaphroditic organisms) all pertain to flatworms.

Stalni domaćin je životinja u kojoj žive larve metilja ili pantljičare.
Correct Answer
B. Netačno
Explanation
The statement "Stalni domaćin je životinja u kojoj žive larve metilja ili pantljičare" translates to "A definitive host is an animal in which the larvae of flukes or tapeworms live." The correct answer is "Netačno" which means "False." Hence, the given statement is not true.
13.
Prelazni domaćin je životinja u kojoj žive odrasli polno zreli metilji ili pantljičare.
Correct Answer
B. Netačno
Explanation
The statement provided states that a "prelazni domaćin" is an animal in which adult sexually mature flukes or tapeworms live. However, this statement is incorrect. A "prelazni domaćin" refers to an intermediate host, which is an organism that harbors the larval or asexual stage of a parasite. The correct answer is "Netačno" (False) because the statement is not accurate.
14.
Stalni domaćin velikog metilja je:
Correct Answer
A. Goveče
Explanation
The correct answer is goveče because it is the host of the large cabbage white butterfly. The butterfly lays its eggs on the leaves of the goveče plant, and the larvae feed on the plant's leaves as they grow. Therefore, goveče is the permanent host of the large cabbage white butterfly.
15.
Prelazni domaćin svinjske pantljičare:
Correct Answer
B. Svinja
Explanation
The correct answer is "Svinja" because the term "prelazni domaćin" refers to an intermediate host in the life cycle of a parasite. In the case of the pork tapeworm (svinjska pantljičara), the pig acts as the intermediate host. This means that the parasite goes through a developmental stage inside the pig before it can infect its final host, which is usually a human. Therefore, the pig is the correct answer as it plays a crucial role in the life cycle of the pork tapeworm.

U parazitske valjkaste crve ubrajamo:- dečju glistu,- čovečju glistu,- trihinu
Correct Answer
A. Tačno
Explanation
The given answer is correct because parasites are organisms that live off of a host organism, and roundworms are a type of parasite. The question asks which parasites are included in the group of roundworms, and the correct answer is "dečja glista" (childhood pinworm), "čovečja glista" (human roundworm), and "trihina" (trichinella). These are all examples of roundworms that can infect humans and cause various health issues.

Najopasniji valjkasti crv za zdravlje čoveka je:
Correct Answer
B. Trihina
Explanation
Trihina je najopasniji valjkasti crv za zdravlje čoveka. Trihina je parazitski crv koji se može naći u sirovom ili nedovoljno termički obrađenom mesu, posebno svinjskom mesu. Kada se unese u ljudski organizam putem kontaminiranog mesa, trihina se razmnožava u crevima i može izazvati ozbiljne zdravstvene probleme. Infekcija trihinom može dovesti do simptoma kao što su bolovi u mišićima, groznica, oticanje lica i očiju, kao i ozbiljne komplikacije poput upale srčanog mišića, pluća ili mozga. Stoga je važno pravilno termički obraditi meso kako bi se ubile potencijalne trihine i sprečila infekcija.

Od ponuđenih člankovitih crva izdvoj onog koji je parazit:
Correct Answer
D. Pijavica
Explanation
The correct answer is "Pijavica" because it is the only one among the options that is a parasite. The other options, such as "Kišna glista" (earthworm), "Glibnjača" (leech), and "Palolo crv" (palolo worm), are not parasites but rather different types of worms with different ecological roles. Pijavica, on the other hand, is a type of worm that attaches itself to the bodies of animals and feeds on their blood, making it a parasitic organism.
