Answer:Type I interferons help protect cells from viral infection. The correct option is B.
Explanation:
Type I interferon (IFNα/β) is a type of cytokine that provides one of the first lines of host defense against viral infection.
Type I interferons act in a paracrine manner such that it have numerous effects on the surrounding cells, preparing them to ward off possible infection. The primary function is to induce protection against viruses in neighboring, non-infected cells. In the target cells they cause digestion of viral DNA and viral proteins.
There is no carbon dioxide balance in biomass output or input. There is no dynamic equilibrium since carbon dioxide is being released at various rates. Geologically carbon dioxide concentration was very high for a long time and high enough to preclude evolving oxygen breathes until when carbon dioxide was locked up in plant life and oxygen levels raised by cyanobacteria and algae.
Oceans release carbon dioxide or it absorbs less carbon dioxide which causes a rise in temperature which feeds back. More heat is lost through evaporation which is lost to upper atmosphere then land biomass starts to pick up.
The correct answer is option c. Several, so that information can be compared and judged based on what it is you are looking for.
When looking for the information online, the person should for all the possible source of information. The information must be taken from the reliable sources. In order to search the data from different sources, the person must search about the topic several times. Each time, he or she should try to search with different keywords, which are related to the topic. In this way, different information can be obtained and can be judged for future use in research and experimentation.
