Answer:
Bacteria are examples of the prokaryotic cell type. ... In general, prokaryotic cells are those that do not have a membrane-bound nucleus. In fact "pro-karyotic" is Greek for "before nucleus". Besides bacteria, the cyanobacteria (blue-green algae) are a major group of prokaryotes.
Answer:
Endospores.
Explanation:
Microorganisms usually adapt to changes in their environment. One example of an extreme survival strategy employed by certain low G+C Gram-positive bacteria, generally of the Firmicute family, is the formation of endospores. They have a very peculiar structure that helps with this survival feature: an outer proteinaceous coat surrounding the spore provides much of the chemical and enzymatic resistance. Beneath the coat there is a very thick layer of specialized peptidoglycan called the cortex, which aids in resistance to high temperature. They are resistant to desiccation, lysozyme, ultraviolet and gamma radiation, chemical disinfectants, starvation AND temperature. So, in this experiment, it is probable that the boiled broth contained endospores, which survived this heating and then reactivated its metabolism.
Chlorophyll is the pigment
Answer:
Its D, The cell membrane(also known a the plasma membrane) has a job in which it has to allow passage in and out of the cell. Therefore it can prevent harmful substances from entering the cell. Think of it as security, either allowing you access or denying you depending on if you're a threat
