Overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change soil erosion, poor air quality and undrinkable water.
It is between A and B.
But if the species is going to be extinct, that means that they are being threatened.
So the answer is B.
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.

Answer:
The environmental impact of a food is the effect that the entire production chain has. From the primary, continuing with the stages of transformation, distribution, use and final disposal. This can translate into: * Global warming
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
