Diversity in Living Organisms Questions

Multiple choice

Which marine parasite is known for its ability to castrate its host, preventing it from reproducing?

  1. Sea lice

  2. Tapeworms

  3. Flukes

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

Some species of flukes, such as the digenean trematode Ribeiroia ondatrae, can castrate their host, preventing it from reproducing. This strategy ensures that the parasite has access to the host's resources for a longer period of time.

Multiple choice

Which marine parasite is known for its ability to form large, cyst-like structures in its host's tissues?

  1. Sea lice

  2. Tapeworms

  3. Flukes

  4. Protozoans
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some marine protozoan parasites, such as Myxobolus cerebralis, can form large, cyst-like structures called myxospores in the tissues of their host. These myxospores can contain thousands of infective spores, increasing the chances of transmission to new hosts.

Multiple choice

Which marine parasite is known for its ability to mimic the appearance or behavior of its host, increasing its chances of transmission?

  1. Sea lice

  2. Tapeworms

  3. Flukes

  4. Copepods
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some species of copepods, such as Caligus rogercresseyi, can mimic the appearance or behavior of their host, making it more difficult for the host to detect and remove the parasite. This strategy increases the chances of the parasite successfully transmitting to new hosts.

Multiple choice

Which of the following is NOT an example of an adaptation?

  1. Camouflage

  2. Mimicry

  3. Migration

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

Migration is a behavior, not an adaptation. Camouflage, mimicry, and hibernation are all adaptations that help organisms survive in their environment.

Multiple choice

What is the scientific name of the Indian slime mold commonly known as the 'flower of tan'?

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

  4. Dictyostelium discoideum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fuligo septica is a plasmodial slime mold that is commonly found in forests and grasslands in India. It is characterized by its bright yellow or orange color and its ability to form large, fan-shaped structures.

Multiple choice

Which Indian slime mold is known for its ability to solve mazes?

  1. Physarum polycephalum

  2. Dictyostelium discoideum

  3. Stemonitis fusca

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

Physarum polycephalum is a slime mold that has been shown to be able to solve mazes and other complex problems. It does this by sending out exploratory tendrils that grow and branch until they find the solution to the problem.

Multiple choice

Which Indian slime mold is commonly found on decaying wood?

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

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

Stemonitis fusca is a slime mold that is commonly found on decaying wood in India. It is characterized by its dark brown or black color and its tall, slender fruiting bodies.

Multiple choice

What is the largest slime mold in India?

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

  4. Lycogala epidendrum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fuligo septica is the largest slime mold in India. It can grow to be several meters in diameter and can weigh up to several kilograms.

Multiple choice

Which Indian slime mold is known for its ability to glow in the dark?

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

  4. Lycogala epidendrum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Lycogala epidendrum is a slime mold that is known for its ability to glow in the dark. This is due to the presence of a chemical called luciferin, which is oxidized to produce light.

Multiple choice

Which Indian slime mold is commonly found on the bark of trees?

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

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

Stemonitis fusca is a slime mold that is commonly found on the bark of trees in India. It is characterized by its dark brown or black color and its tall, slender fruiting bodies.

Multiple choice

  1. Physarum polycephalum

  2. Fuligo septica

  3. Stemonitis fusca

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

Physarum polycephalum is a slime mold that is commonly found in grasslands in India. It is characterized by its bright yellow or orange color and its ability to form large, fan-shaped structures.

Multiple choice

What is the role of slime molds in the control of populations of bacteria and fungi?

  1. They produce antibiotics that kill bacteria and fungi.

  2. They compete with bacteria and fungi for resources.

  3. They help to create a favorable environment for the growth of beneficial bacteria and fungi.

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

Slime molds play an important role in the control of populations of bacteria and fungi by producing antibiotics that kill bacteria and fungi, competing with bacteria and fungi for resources, and helping to create a favorable environment for the growth of beneficial bacteria and fungi.

Multiple choice

Which of the following is an example of a homologous structure?

  1. The wings of birds and bats

  2. The eyes of humans and octopuses

  3. The digestive system of cows and sheep

  4. The immune system of humans and chimpanzees
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A homologous structure is a structure that has the same basic form and developmental origin in different organisms. The wings of birds and bats are an example of homologous structures because they both evolved from the forelimbs of a common ancestor.
