Archaea are different from Eubacteria are different types of prokaryotes because... Archaea lack a nucleus Archaea are unicellular Archaea lack peptidoglycan in their cell wall Archaea do not have ribosomes

Which of the following statements is correct for archaea?(a) Archaea resemble eukaryotes in all respects.(b) Archaea have some novel features that are absent inother prokaryotes and eukaryotes.(c) Archaea completely differ from both prokaryotes andeukaryotes.(d) Archaea completely differ from prokaryotes   Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.

Part B: Observation of Prokaryotic Cells Because of the small size of prokaryotic cells, your observation will focus on distinguishing between cell shape and cell arrangement. Together, appearance and arrangement are used to characterize bacteria. Bacteria have three basic shapes (Figure 7.1): cocci (spherical), bacilli (rod), spirilla (spiral). Bacteria can also be differentiated based on their cell arrangement (Figure 7.1): diplo (pairs), strepto (chains), staphylo (clusters). Activity 2: Observe Prokaryotic Cell Specimen Refer to each photo and answer the question using the information provided in Figure 7.1 and Table 7.2 Domain= Coccus single chain pair tetrad 8 8 8 Bacillus single fusiform chain Spirillum Specimen = What identifying characteristics of this organ- ism helped you to determine its specimen's name? Domain= Specimen name= What identifying characteristics of this or- ganism helped you to determine its speci- men's name? CHayden-McNeil, LLC Domain= Figure 7.1. Bacterial…

In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? Question options:   They both have identical cell walls.   They both have prokaryotic cells.   They both thrive in extreme environments.   They both are able to live only under anaerobic conditions.
