#1: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella. #2: Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences. #10: Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. #12: Bacteria reproduce .In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Each daughter cell is a clone of the parent cell. #13: Pathogenic bacteria are bacteria that can cause disease. ... One of the bacterial diseases with the highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub-Saharan Africa. Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.Pathogenic microbes challenge the immune system in many ways. Viruses make us sick by killing cells or disrupting cell function. #14: Antibiotics work by affecting things that bacterial cells have but human cells don't. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. HOPE I HELPED I Don’t NO #11
Answer:

Gradualism is referred to the theory about how fast evolution occurs in this type of species.
<h3>What is
Gradualism?</h3>
This type of evolutionary changes occurs gradually and not in large steps or volume.
This however explains why the species had very little changes for a very long time as a result of the environment being best suited for them.

Answer:
The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve(cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon.[3]Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.[4] The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic
