Parasitology

Question 3

Answer 3

Medical Parasitology

Question 4

It literally means “living together” which involves transportation, protection, and other advantages to parasites.

Answer 4

Symbiosis

Question 5

It occurs when two organisms living in close association commonly one living in or on the body of the other.

Answer 5

Symbiosis

Question 6

TRUE or FALSE.

It is necessary for symbionts to be of different species.

Answer 6

FALSE. Symbionts are of different species but not necessarily.

Question 7

It is a type of symbiotic relationship where one benefit while the other is neither benefitted nor harmed.

Answer 7

Commensalism

Question 8

A type of symbiotic relationship that can also be referred as “eating at the same table.”

Answer 8

Commensalism

Question 9

In commensalism, the organisms that provides the benefits are called ______, while the recipient of the benefits are called ______.

Answer 9

Host (provider), Commensal (receiver)

Question 10

Give 3 example of benefits or service that can be acquired from symbiotic relationships.

Answer 10

Transportations, Protection, Resources (nutrients)

Question 11

The relationship between a nematode (Caenorharbditis remanei) and mollusks (snail) is an example of what type of symbiosis.

Answer 11

Commensalism

Question 12

The interaction between a nematode (Caenorharbditis remanei) and mollusks are strictly for ________ and to avoid __________________.

Answer 12

Dispersal

Harsh environment conditions

Question 13

It is a special type of commensalism wherein both organisms benefit from one another.

Answer 13

Mutualism

Question 14

It is a type of obligatory symbiosis because of its physiological dependence on one another, which means one cannot survive without the other.

Answer 14

Mutualism

Question 15

The interaction between a wood-eating termite and intestinal microbiota (which is an intestinal protozoan) is an example of what type of symbiosis?

Answer 15

Mutualism

Question 16

How does intestinal microbiota aids the wood-eating termite?

Answer 16

Intestinal microbiota aids in lignocellulose degradation

Question 17

It is a type of symbiosis wherein two symbionts are merely “travelling together “ and neither is physiologically dependent on the other.

Answer 17

Phoresy

Question 18

In phoresy, _______ is usually smaller than the other organism and is mechanically carried about by that organism called ______.

Answer 18

Phoront or Phoretic Animal

Companion

Question 19

TRUE or FALSE.

The relationship between mites and bees is an example of parasitism.

Answer 19

FALSE. It is a phoresy, because mites uses bee as transportation but not inducing parasitism.

Question 20

A type of symbiosis wherein the symbiont actually harms it host or in some sense lives at the expense of the host. It involves intimate relationship between two species with prolong contact or interaction.

Answer 20

Parasitism

Question 21

A type of parasite that lives on the surface of its host is called endoparasite.

Answer 21

False.

Question 22

A type of parasite that lives internally on its host is called endoparasite.

Answer 22

True.

Question 23

It is a type of parasite that spends at least a part of their lives as parasites to survive and complete their life cycles.

Answer 23

Obligate Parasite

Question 24

These parasites are not normally parasitic but can become so, if they are accidentally eaten or enter a wound or other body orifice.

Answer 24

Facultative Parasites

Question 25

A type of parasite that lives its entire adult life within or on their host.

Answer 25

Permanent Parasite

Question 26

A parasite that only feeds on the host and then leaves.

Answer 26

Temporary or Intermittent Parasite

Question 27

A parasite also called micropredator since they prey on several different hosts.

Answer 27

Temporary or Intermittent Parasite

Question 28

A type parasite that enters or attaches to the body of a species or host different from its normal one is called __________.

Answer 28

Accidental or Incidental Parasite

Question 29

Accidental parasites are unable to stay long on, or live long in the wrong host.

Answer 29

True

Question 30

It is a free-living parasite or organism that passes through the digestive tract without infecting the host.

Answer 30

Spurious Parasite
