Purpose: The purpose of this lab is to test what substances are necessary for muscle contraction. Hypothesis: Based off the frog muscle immersed separately in Solution A of ATP and distilled water solution‚ Solution B of ATP with KCl in distilled water and MgCl2 in distilled water and solution C of KCl and MgCl2 in distilled water‚ I hypothesize that solution B of ATP with KCl in distilled water and MgCl2 in distilled water will cause the muscle to contract. Introduction: This lab consisted of

mechanical properties of a cell. Fibrillar polymer filaments‚ microtubules‚ and intermediate filaments are major constituents of the cytoskeleton‚ which constantly change their organization during cellular activities. The actin cytoskeleton is especially polymorphic‚ as actin filaments can form multiple higher order assemblies performing different functions. Structural information about cytoskeleton organization is critical for understanding its functions and mechanisms underlying various

BTEC Level 3 Applied Science Unit 1 – examiners report: Achieves P5‚ M2 needs to discuss different tissue types to achieve D2. In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as
