The cell wall is an outer protective membrane in many cells including plants, fungi, algae, and bacteria. Animal cells do not have a cell wall. The main functions of the cell wall are to provide structure, support, and protection for the cell
Answer:
Bacteria that are helpful in one place may be harmful in another.
What information in the text supports this statement?
A Heliobacter pylori is a bacterium that causes gastritis (irritation or
inflammation of the stomach lining) and peptic ulcers, diseases which were once
thought to be caused by too much acid.
B Streptococcus salivarius appears to help prevent tooth decay in the mouth
but can be dangerous to people with weakened immune systems if it gets
outside the mouth.
Bacillus subtilis releases toxic chemicals to kill fungus, possibly including
Trichophyton interdigitale and other species that cause athlete's foot.
D Skin, which is our interface with the world, supports a large number of the
human body's most diverse populations of bacteria, including Bacillus subtilis.
Explanation:
The Nucleus contains most of the genetic information for making proteins
The ribosome is the place where the polypeptide strand and the mRNA meet in order to create a protein
Nucleolus has a role in the biogenesis of the ribosomes
RER -intracelular transport and protein making because of the attached ribosomes
SER-intracelular transport,lipid synthesis and it is the place where the glicogen is metabolized
Golgi Apparatus has a secretive role
Lysosomes contain 40+ hydrolytic enzimes that help with intracelular digestion
Cilia and flagella both help with the moving of the cell
Extracellular matrix keeps the cells together
The Mitochondria sythesizes ATP in a process caled oxidative phosphorylation of organic substances
Answer: All cells come from preexisting cells.
Explanation:
The given paragraph is about cells develop from the preexisting cells. The doubling of the genetic material in the S-phase is the triggering mechanism for cell division. In the process of mitosis the genetic material get reduced. The daughter cells vary by the amount of genetic material they receive. This proves that the new cells form from the pre-existing cells.
