#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

epithelium: found in cartilage
connective: found in cartilage
Explanation:
Answer:
Due to being nearsighted.
Explanation:
Nearsightedness can also be caused by the cornea and/or lens being too curved for the length of the eyeball. In some cases, myopia occurs due to a combination of these factor
Answer:
• covers the body and makes up inner lining
• protects against damage, dust, bacteria
Explanation:
Answer:
16.66 %
Explanation:
The receptors that are bound with the ligand can be calculated by the formula as follows:
Kd = [R] [L]/[RL]
Here, Kd is dissociation constant = 1.5 mM
R is free receptor concentration = 10 mM
L is free ligand concentration = 2.5 mM
The values needs to be constitute to find the percentage of receptors that are bound to ligand.
Put all the values
1.5 = 10 × 2.5 / RL or RL = 25 /1.5
So RL = 16.66
Hence 16.66 % of receptor is bound to substrate.
Thus, the answer is 16.66%
