Which of the following is a likely conclusion to draw from this information tubular genes are evolutionarily derived from the gene that codes for the FtsZ protein
experimental evidence shows that the process of glycolysis is present and visually identical in organisms from all three domains, Archaea, Bacteria, and Eukarya. Which of the following hypotheses could be best supported by this evidence? glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life simple cuboidal epithelial cells line the ducts of certain human exocrine glands. Various materials are transported into or out of the cells by diffusions. which of the following cube-shaped cells would be most efficient in removing waste by diffusion? 10 um which of the following is true about the structure of the prokaryotic cell represented in the figure? it has a cell wall exterior to the plasma membrane and contains ribosomes the figure above represents a rough endoplasmic reticulum. Which of the following best describes the role of the structure labeled Y? structure Y is the location where proteins are synthesized Cilia and eukaryotic flagella must have a motor protein that uses the energy of ATP hydrolysis to power movement amoeba proteus is injectie with a drug that inhibits the formation of microtubules. What effect will this have on the organisms movement? the drug will have no effect on the organisms movement which structure occupies the largest volume in a mature plant cell? vacuole liver cells are exposed to radioactive amino acids, making all proteins synthesized during this time radioactive. the cells are them removed at 5-minute intervals and fractionated. Where in the cells is the radioactively-labeled enzyme lipase performing its intracellular functions? in lysosomes the firgure below illustrates a eukaryotic cell. Which of the following best describes how the three structures indicated by the arrows work together? rough ER, golgi apparatus, vesicle to synthesize and isolate proteins for secretion or for use in the cell which of the following best describes an advantage that eukaryote organisms have over prokaryote organisms? eukaryotes have organelles that allow for compartmentalization of cellular processes, which increases the efficiency of those processes most of the cells in the human body are: smaller than the period at the end of this sentence, but larger than most bacteria. if a physician took a biopsy of one of your lymph nodes and wanted to see quickly if the cells in their living state looked normal, she could observe the cells using a light microscope members of the domains Bacteria and Archaea have ribosomes but no endoplasmic reticulum you find a perviously unknown single-celled organisms in a water sample. While studying it, you find that the organism is photosynthetic and has a cell membrane surrounded by a layer of peptidoglycan (carbohydrates linked to peptides). the organism contains DNA and RNA but you see no nuclear membrane. This organisms most likely belongs to which group? bacteria (photo of flagella) if you could observe the living organism shown in the figure above, you would see that it can use the structures labeled 1 to swim in a cork-screw like motion the photograph of the organism (flagella) was most likely taken with a : electron microscope a typical human lymphocyte has a radius of about 10 um, while a typical bacterium has a radius of about 1 um. assuming that both cell types are perfectly spherical, how many times larger is the surface area of a typical human lymphocyte compared to the surface area of a typical bacterium? 100

A different cell has a surface area of 36 um2 and a volume of 12 um3. what is the ratio of surface area to volume for the cell that is predicted to exchange materials with the surrounding environment at a faster rate by diffuse? 4 a) describe the structure and function of two eukaryotic membrane bound organelles other than the nucleus b) prokaryotic and eukaryotic cells have some non-membrane bound components in common. Describe the function of two o the following and discuss two each differs in prokaryotes and eukaryotes c) explain the endosymbiotic theory of the origin of eukaryotic cells and discuss an example of evidence supporting this theory a) two organelles in eukaryotes are mitochondria and vacuoles. Mitochondria

BIOLOGY A human gene was initially identified as having three exons and two introns. The exons are 456, 224, and 524 bp, whereas the introns are 2.3 kb and 4.6 kb. a. Draw this gene, showing the promoter, introns, exons, and transcription start and stop sites. b. Surprisingly, this gene is found to encode not one but two mRNAs that have only 224 nucleotides in common. The original mRNA is 1204 nucleotides, and the new mRNA is 2524 nucleotides. Use your drawing to show how this one region of DNA can encode these two transcripts. Verified answer

First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby increasing the rate and efficiency of chemical reactions.
How internal membranes and organelles contribute to cell functions?In eukaryotes, the internal membranes partition the cell into specialized regions that allow cell processes to operate with optimal efficiency. Each compartment or membrane-bound organelle enables localization of chemical reactions.
What is the advantage of having organelles in cells quizlet?Why are organelles important to eukaryotic cells? Organelles are structures found in cells that perform specific functions, and organelles are important because they allow chemical processes to occur at the same time without interfering with one another.
What is the importance of internal membranes in eukaryotic cells?Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
