  1. Anisakis simplex

  2. Pseudoterranova decipiens

  3. Phocanema decipiens

  4. Contracaecum osculatum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Anisakis simplex is a nematode that causes anisakiasis, a parasitic infection that can occur when raw or undercooked fish containing the larvae is consumed.

  2. Gnathostoma hispidum

  3. Gnathostoma doloresi

  4. Gnathostoma nipponicum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gnathostoma spinigerum is a nematode that causes gnathostomiasis, a parasitic infection that can occur when raw or undercooked fish or poultry containing the larvae is consumed.

Multiple choice

  1. Streamlined body shape

  2. Gills for respiration

  3. Camouflage coloration

  4. Ability to withstand high water temperatures
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A streamlined body shape helps aquatic insects reduce drag and move efficiently through the flowing water of riverine ecosystems.

Multiple choice

Which anatomical feature is unique to humans and distinguishes them from other primates?

  1. Bipedalism

  2. Opposable thumbs

  3. Large brain size

  4. Absence of a tail
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bipedalism, or the ability to walk upright on two legs, is a defining characteristic of humans. It allows for efficient movement, freeing up the hands for tool use and other activities.

Multiple choice

Which of the following is a characteristic of prokaryotic cells?

  1. They have a nucleus.

  2. They have membrane-bound organelles.

  3. They have a cell wall.

  4. They have a cytoskeleton.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Prokaryotic cells, unlike eukaryotic cells, do not have a nucleus or membrane-bound organelles. They do have a cell wall, which provides structural support and protection.
