Explain the adaptive defense system
Choose the correct defense mechanism for each of the following statemnts. The choices are: behavioural defense, cryptic colouration, protective colouration and mimicry. A defense mechanism can be used more than once. Please explain in detail why each defense mechanism was picked.Examples:
A walking stick insect blends into the twigs in its habitat. Answer
A defenseless organism looks like a poisonous model. Answer
Two poisonous species evolved to look very similar in order to intensify the deterrence from predators. Answer
Orange elephant ear sponge is bright orange coloured and lives on ocean reefs. Answer
Cinnabar moth caterpillars have distinct black and yellow stripes. Answer
Hagfishes automatically produce fibrous slime from their body when they are captured. Answer

- Which of the following is NOT a mechanism used by the immune system to fight multicellular parasites? Select one: a. Antibodies coating the pathogen surface bind to FcRs on mast cells, causing release of granule contents onto surface, and damage the parasite. b. Crosslinking of antibody binding to FceRI on eosinophils cells triggers release of granules, causing smooth muscle contractions. Muscle contractions in the mucosal tracts causes sneezing, coughing, vomiting or diarrhea, dislodging the parasite. d. The parasite is killed and broken down extracellularly, and then phagocytosed by macrophages. C.arrow_forwardTOPIC: Immune System Process in Plants and Animalsarrow_forwardHelp answerarrow_forward

Check all that apply. PAMPs recognize pathogen recognition receptors (PRRs) such as TLRs, NLRs and RLRs present on/in host cells TLRs that are expressed on cell surface are mostly recognized by viruses, whereas intracellular TLRs are recognized by bacteria PRRs can induce inflammatory response, opsonization and phagocytosis Pattern associated molecular patterns (PAMPs) are molecules such as CpG DNA, cytosolic dsDNA and RNAs made by the host cellarrow_forward
- The impact of communicable diseases (infectious diseases) on human health is obvious. The sudden outbreak of “severe acute respiratory syndrome coronavirus 2” [SARS-CoV-2]” (COVID-19) has made people realize the threat of communicable diseases and their threat to mankind as a complex humanitarian emergency.
