  1. Coral Spawning

  2. Coral Bleaching

  3. Coral Predation

  4. Coral Disease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coral spawning is the process by which corals release eggs and sperm into the water, allowing for fertilization and the formation of new coral colonies.

Multiple choice

What is the process by which worker bees convert nectar into honey called?

  1. Regurgitation

  2. Fermentation

  3. Distillation

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

Worker bees regurgitate nectar and pass it between their mouthparts, adding enzymes that break down complex sugars into simpler ones, resulting in the production of honey.

Multiple choice

What is the process by which coral reefs reproduce and expand their colonies?

  1. Fragmentation

  2. Budding

  3. Spawning

  4. Pollination
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Coral reefs reproduce primarily through spawning, where male and female corals release their gametes into the water, resulting in the formation of new coral colonies.

  2. Fertilization

  3. Gestation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Reproduction, fertilization, and gestation are all terms used to describe the process by which marine organisms reproduce and create offspring.

Multiple choice

What is coral bleaching?

  1. When corals lose their symbiotic algae

  2. When corals turn white

  3. When corals die

  4. When corals reproduce
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coral bleaching occurs when corals lose their symbiotic algae, called zooxanthellae, which provide them with food and color.

  1. Courtship

  2. Mating

  3. Incubation

  4. Hatching

Multiple choice

What is the primary mode of reproduction for most freshwater protozoa?

  1. Binary fission

  2. Budding

  3. Conjugation

  4. Multiple fission
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Binary fission is the most common mode of reproduction for freshwater protozoa. During binary fission, the protozoan cell divides into two identical daughter cells, each inheriting a copy of the genetic material.

Multiple choice

Which of the following is a characteristic of semelparous fish?

  1. They reproduce multiple times during their lifetime.

  2. They reproduce only once during their lifetime.

  3. They produce a large number of offspring at once.

  4. They produce a small number of offspring at once.

B Correct answer
Explanation

Semelparous fish reproduce only once during their lifetime, typically releasing all of their eggs or sperm at once in a single spawning event.

Multiple choice

Which of the following is a type of asexual reproduction found in some fish and shellfish?

  1. Budding

  2. Fragmentation

  3. Parthenogenesis

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Budding, fragmentation, and parthenogenesis are all types of asexual reproduction found in some fish and shellfish. Budding involves the formation of a new individual from an outgrowth of the parent's body. Fragmentation involves the breaking of the parent's body into several pieces, each of which can develop into a new individual. Parthenogenesis involves the development of an embryo from an unfertilized egg.
