The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - Correct answer-true In your own multicellular body, cells with different functions have different DNA. - Correct answer-false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - Correct answer-true The paramec...

Write a few sentences that explain what limits an individual cell from becoming more complex. - Correct answer-Bimolecular machinery and division of labor The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-Kidney In cell Biology what can limit the progress of science? - Correct answer-Technology True or False: In you own multicellular body, cells with different functions have different DNA - Corre...

Describe how you would use a biochemical test to show that a solution contained a non-reducing sugar, such as sucrose. [3] - ANSWER,first reducing sugars test; boil with dilute HCl acid then Neutralise with NaHCǑ, add benedict and heat to 95 degrees C brick red ppt forms if reducing sugar is present Describe a chemical test you could carry out to show that a piece of coconut contains lipids. [3] - ANSWER(Crush in) ethanol / alcohol; Add (to) water (Order of adding is critical for this point)...

MBB347 FINAL EXAM QUESTIONS WITH ANSWERS Determine if the following features characterize eukaryotes, prokaryotes, both groups, or neither group. 1. They use a deoxyribonucleoside triphosphate as their "energy currency". 2. They chiefly use deoxyribonucleic acid molecules to store genetic information. 3. RNA molecules are their main catalysts. 4. Their DNA is typically found within sub-cellular organelles such as mitochondria, chloroplasts but mainly in the nucleus. 5. Their pr...

Honors Biology Unit 1 Study Guide Questions With Complete Solutions What role do proteins play in cellular processes? Proteins serve as enzymes, structural components, and signaling molecules, playing a key role in cellular functions. How does the structure of a phospholipid contribute to the formation of cell membranes? Phospholipids have hydrophilic heads and hydrophobic tails, forming a bilayer that creates a selective barrier for the cell. Why is the process of homeostasis cr...
