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...

Phosphatase correct answers This myosin-actin interaction forms the basis of the cross-bridge cycle (CBC), which causes muscle contraction, as in skeletal -bridge cycling (CBC) requires phosphorylation of the myosin light chain (LC20). A .............. is an enzyme that removes a phosphate group from its substrate composed of actin and are dynamic and are lengthen by polymerization or shortened by depolarization correct answers microfilaments are provide strucule support for the cell ...

BPK 105 Exam Questions and Answers 2024/2025 | A+ GRADED 100% VERIFIED What is actin? Actin is a thin protein filament in muscle fibers that works with myosin for muscle contraction. What is myosin? Myosin is a thick protein filament in muscle fibers that interacts with actin to cause muscle contraction. What is a sarcomere? A sarcomere is the basic contracting unit in a muscle fiber, made of actin and myosin. What is troponin? Troponin is a protein on actin filaments; it binds calcium a...
