The right answers are:
Peptidoglycan, present in bacterial cell wall.
Chitin, present in fungi cell wall.
Anaerobes, incapable of surviving with oxygen.
Pseudopodia, used to engulf food.
Step-by-step explanation:
* The peptidoglycan (or murein, or mucocomplex, or mucopeptide) is a glycosaminopeptide polymer wherein N-acetyl-glucosamine (NAG) and N-acetyl-muramic acid (NAM) are linked by osidic bonds.
Peptidoglycan forms the bacterial wall of Gram-positive and Gram-negative bacteria, providing cell shape and mechanical and physical protection.
* Chitin is a polymeric substance comparable to cellulose but nitrogenous since it is an acetylglucosamine. It enters, in particular, in the composition of the integument of the arthropods (insects, arachnids, and crustaceans), nematodes, as well as in that of the wall of the eumycetes.
* Anaerobes refers to a living being or a phenomenon that does not need oxygen to exist. In contrast, aerobics. Example: conversion of nitrates to gaseous nitrogen (4NO3- + 4H3O + to 2N2 + 6H2O + 5O2), as do clostridium, for example.
* Pseudopods are deformations of the plasma membrane that allow a cell to feed and crawl on a support in a specific direction.
