Which cells are the most unspecialized mass of cells? What do plant cells have that animal cells do not? What are two types of cell categories found in nervous tissue? What are their roles? The powerhouse of a cell in living organisms is called what?
Cells are to tissue as tissue are to [{Blank}]? a) organs b) Membranes c) Organ systems d) Organelles e) OrganismsGroups of similar cells and extracellular products that carry out a common function are: A) organ systems. B) tissues. C) organs. D) matrices.Which of these...
What Are the Different Categories of Cells? Rather than grouping cells by their size or shape, scientists typically categorize them by how their genetic material is packaged. If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, ...
Describe the function of organelles, cells, tissues, and the organ system as well as their role in the cell. Under which categories should mucous bacteria and fever be put - specific immunity or nonspecific immunity? How can the nucleus be separated from cell during cloning?
Why badges are helpful for the Pre-A&P course, how they are earned, and what they signify. Documentation of badge competencies.
Oxygen radicals, such as H2O2, are produced by normal cellular processes. Since they are dangerous to the cell, they must be converted into benign molecules. Catalase is one of the fastest enzymes known. Each monomer in the catalase tetramer can perform nearly 200,000 catalytic events per secon...
Composition and Structure of ChromosomesChromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, ...
Then the rRNA and proteins are assembled into two subunits, one large and one small, that will eventually combine to create a single ribosome. These subunits leave the cell's nucleus via pores found in the nuclear membrane. They enter the cytoplasm of the cell, where they come together to ...
All living things belong to one of two broad categories: prokaryotes and eukaryotes. Prokaryotes are the single-celled organisms of the taxonomicdomainsBacteria and Archaea, whereas eukaryotes all fall into the domain Eukaryota, which includes animals, plants, fungi and protists. ...
What are the three major similarites and differenes between prokaryotic and eukaryotic cells? What is one main way in which prokaryotic and eukaryotic cells differ? a) Prokaryotic cells have a nucleus and eukaryotic cells do not. b) Prokaryotic cells have membrane-bound organelle...
