IB Biology 1.2 Latest Update Already Passed Resolution Resolution is defined as the shortest distance between two points that can be distinquished Explain why electron microscopes have a better resolution than light microscopes because the wavelength of the electrons is thousands of times smaller than the wavelength of light. Ultrastructure all the structures of a biological specimen that are at least 0.1 nm in their smallest dimension Something that electron microscopes can se...

BIO 120 3rd Exam: Intracellular Protein Sorting and Maintenance of Cell Compartmentalization Compartmentalization - Due to network inside the cell Eukaryotic Cell Compartment Assembly of organelle depends on protein transported to it Highly regulated, specific and targeted Intracellular Compartment Nucleus continuous in cytosol (topologically continuous) o Molecules can move from one place to another without crossing the membrance Secretory and endocytic network o Vesicles, endoso...

Discuss the differences between "flush cuts" and proper cuts made to outer portions of branch collar. How do "flush cuts" affect growth? - Answer-A proper cut leaves the branch bark ridge, branch collar, and swollen collar in tact. It enables the cut to close in a circular fashion. Flush cuts remove it and opens the tree to decay by removing dead wood which branch defense zones form. Explain thinning cut and describe how they will affect the tree. - Answer-It is removing the branch back t...

What is the stinging organelle that assists it in capturing large prey? Trichocyst Which species of amoeba did you observe under the microscope? Amoeba proteus Which experimental group receives the treatment? Control group A solution that tends to release protons is An acid The portion of a phospholipid that contains the phosphate group has one or more electrical charges. That makes this region of the molecule Hydrophilic The Biuret test is used to detect the presence of which group of mac...

Compartmentalization correct answers The segregation of functions into different compartments; in the cell, increases the efficiency of chemical reactions Lipid correct answers Any organic molecule that is poorly soluble or virtually insoluble in water but is soluble in nonpolar organic solvents; make up the membranes of cells Membrane correct answers Made of either phospholipids or phospholipids and sterols; often bilayers with polar head group facing outside from hydrophobic tails Per...

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - Answer-The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...
