Yes Bacteria are considered to be prokaryotes,it means they dont have a nucleus or other membranes but instead the DNA is in the neceloid,a region with no membrane or a plasmid a small circle of extra genetic info floating right in the cytoplasm the thing that fills the cell. so yes they do have DNA they dont need a necleus the just need the neceloid
Major parts of the animal cell:
Nucleus- controls the cell's activities and contains all the genetic material
Nucleolus- is involved in the synthesis of ribosomal RNA. It is a dark body inside the nucleus
Nuclear membrane- keeps DNA inside the nucleus but allows mRNA and proteins through. It is a double membrane with large pores
Golgi Complex- store and package cellular secretions for export out of the cell (usually through the use of vacuoles). Salivary, oil, and digestive glands have very active golgi bodies.
Rough Endoplasmic Reticulum-is a series of long canals running throughout the cell with ribosomes attached. It transports proteins to the golgi bodies for packaging.
Smooth Endoplasmic Reticulum- is a series of long canals running throughout the cell. It detoxifies the cell and converts foodstuffs.
Centrioles- anchor spindle fibers during cell division. They are composed of microtubules and are only found in animal cells.
Mitochondria- produce most of the cell's energy. They are composed of two membranes (an outer and a folded inner membrane) and are common in muscle cells
Ribosomes and Free Ribosomes- assemble proteins from RNA codes. They are found free-floating in the cytoplasm throughout the cell or attached to the endoplasmic reticulum
Lysosomes-digest and remove worn out cell organelles. In essence, they are vacuoles filled with digestive enzymes.
Answer:
the 2nd and 4th
Explanation:
they contain more than one molecule due to them being different elements
Explanation:
HCl + Ca(oh)2 = CaCl2 + H2O
