#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:
<h2>
Mitosis and meiosis are the ways of cell division which result daughter cells for growth, development and reproduction.
</h2>
Explanation:
Mitosis and meiosis result daughter cells for growth, development and reproduction in the living world.
Mitosis results two similar daughter cells which are generally for growth and development. In asexual mode of reproduction, mitosis helps in increasing the number of cells.
Meiosis occurs in germ cells, and in meiosis, one diploid cell produce four haploid cells.
Meiosis results variations by independent assortment and by crossing over and it helps the sexual mode of reproduction. During fertilization, the resultant daughter haploid cells unite and retains the diploid number of chromosomes.
Answer:
They are typically larger than prokaryotic cells
The DNA of a eukaryotic cell is contained in the cell nucleus.
Answer: I think its cells
Explanation:
Viruses dont have cells
C. The nuclear envelope contains the nucleus and forms a barrier between it and the cytoplasm
