Clownfish have evolved resistance to the deadly stings of sea anemones. The sea anemone provides protection for the clownfish from predators and leaves the uneaten remains of its prey for the clownfish to finish off. Meanwhile the clownfish helps attract prey to the sea anemone with its bright colors. The relationship between clownfish and sea anemones is a form of symbiosis called?

Answers

The answer is mutualism.


Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.

Answer:

mutalism

An earthworm tunnel floods during a rainstorm, and the earthworm washes out onto the grass. According to Ch.27, what is the importance of the moisture from the tunnel to the earthworm?

Answers

Answer and explanation;

  • The moisture pertains to its survival due to its respiratory surface. Such that too much water and the earthworm could die and  too little water and the earthworm could dry up and die. Keeping their skin moist allows them to respire.
  • Earthworms are important as they plow the soil by tunneling through it, which provides the soil with passageways through which air and water can circulate.
  • The activity of the earthworms depends directly on soil moisture and temperature. They become active when soil thaws in the spring and move deeper in late summer as the soil dries.
The moisture from the tunnel to the earthworm is how they survive, too much moisture will kill them. And there abundant food source is located there.

1. Mike injured his knee while playing. Examination revealed that the injured area was red, swollen, and warmer than the surrounding area. What does this condition indicate?an inflammation

a tumor–like growth

a hemorrhage

2. When a virus invades the body, some B cells recognize it as nonself and produce plasma cells that release a substance to kill the virus. What is this substance called?

antigen

antibody

pathogen

3. Which of the following forms blood clots?

fibrin

macrophages

thrombin


4. An antigen has invaded a mammal's body. Specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells' bodies. What happens next?

B cells are activated and release antibodies.

T cells are activated and produce clones.

B cells withdraw the immune response as the antigen is killed.

Answers

1. Inflammation

2. Antibody

3.Thrombin

4. B cells are activated and release antibodies.

Final answer:

The conditions described by Mike all point to an inflammation, not a tumor-like growth or hemorrhage. When a body is invaded by a virus, B cells produce antibodies to destroy it. Fibrin is responsible for blood clot formation. When pieces of a digested antigen are displayed on a cell's body, it prompts T cells to activate and produce clones.

Explanation:

1. Mike's knee injury which revealed a red, swollen, and warmer area than the surrounding indicates an inflammation. This is a protective response to injury or destruction of tissues which serves to destroy, dilute, or wall off the injurious agent and the injured tissue.

2. When a virus invades the body, some B cells recognize it as foreign and produce plasma cells that release a substance to kill the virus. This substance is referred to as an antibody.

3. Fibrin is responsible for the formation of blood clots. It is a fibrous protein that helps control bleeding and forms a meshwork at a wound site, creating a clot to prevent further bleeding.

4. When an antigen invades a mammal's body, specific immune cells engulf and digest it. The digest pieces are displayed on the cells' bodies leading to the activation of T cells which then produce clones.
