Answer:
A living organism whose genes have been purposefully altered
Explanation:
The correct answer is B. A bony skeleton
Explanation:
In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
Answer:
D(Movement
Explanation:
The integumentary system, which includes the skin, protects the body and regulates temperature/homeostasis. It also eliminates small amounts of waste, but it does not aid in movement directly.
Small proteins released from tissue cells infected with viruses, as well as from activated lymphocytes and macrophages, are called Interferons
<h3>What are Interferons ?</h3>
A collection of signalling proteins known as interferons are produced and released by host cells in response to the presence of certain viruses. Typically, a virus-infected cell will release interferons, boosting the antiviral defences of neighbouring cells.
- They are released by infected cells, where they trigger the innate immune system's production of cytokines as well as natural killer cell activity and antigen presentation.
- By establishing cytokine barriers, interferons shield uninfected cells from subsequent viral infections. Additionally, they prevent cellular division and control the organism's immune response.
