Endoderm forms the epithelium—a type of tissue.
Answer:
The answers are b) Disinfection can occur by physical or chemical mean, c) Disinfectants are used to inhibit or destroy pathogens, d)Endospores and viruses can resist disinfectant treatment and e)Disinfection can be used to treat work surfaces as well as workers (i.e., washing hands)
Explanation:
Disinfection is the process that involves the elimination of microorganisms through the use of chemical or physical agents. Among the physicists are heat, radiation, drying, etc. Chemical disinfectants are oxidizing substances that are used in solution and can be combined with detergents or some organic substances.
However, endospores and some viruses are very resistant to both physical and chemical disinfection. In endospores, this resistance is due to the fact that the protective layer of the spore is impermeable to any oxidizing agent. In viruses, the cytoplasmic membrane is composed of two layers, a hydrophobic and a hydrophilic zone, this influences the resistance to disinfectants.
the answer is false they mostly form branch chains
Answer:
auditory ossicles
Explanation:
In reptiles, the eardrum is connected to the inner ear via a single bone, the columella, while the upper and lower jaws contain several bones not found in mammals. Over the course of the evolution of mammals, one bone from the lower and one from the upper jaw (the articular and quadrate bones) lost their purpose in the jaw joint and were put to new use in the middle ear, connecting to the existing stapes bone and forming a chain of three bones, the ossicles, which transmit sounds more efficiently
