conditions do cells gain or lose water? Did water move into the cell or out of the cell while it was surrounded by hypotonic solution? The water moved into the cell‚ because there was less water inside the cell than outside (there were fewer water molecules inside). 2. In which direction did the water move though the cell membrane when the cell was surrounded by the hypertonic solution? The water moved out of the cell because there was a higher concentration of water inside the cell than outside

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

Nick Work October 20‚ 3013 CSI: Intro to Biology Blood Sampling Objective Our Objective is to identify which blood type each sample is. We test Anti-A and Anti – B‚ and also test to determine if it is Rh positive or negative. Hypothesis We are testing unknown blood sample testing for what type of blood. When A is shown in the blood sample agglutination will accrue causing it to look grainy. Materials At least 4 dropper vial 3 blood samples Synthetic Anti – A Synthetic Anti –B Synthetic

Cells and Movement of Substances All living things are formed by cells‚ the structure of these cells varying depending on their function. Animal and plant cells have common features such as a nucleus‚ cytoplasm and cell membrane. Dissolved substances pass into and out of cells by diffusion Diffusion Diffusion definition: Diffusion is the movement of molecules from a high concentration to a low concentration. Dissolved

The understanding of blood spatter patterns is not a widely recognized forensic practice. Bloodstain pattern interpretation (BPI) is commonly used in murder investigations‚ but could be utilized in everything from simple assault to mass murders if the number of trained professionals increased. BPI can reveal critical information into reinventing a given crime scene. Everything from the number of blows‚ stabs or shots a victim was given‚ the movement that was undergone by the victim and assailant

the process of diffusion and be distributed throughout the coffee. Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules on both sides of the cell membrane. 1.2 The important factors in the process of diffusion and osmosis is H2O being present with soluble molecules that are small enough to be absorbed through the cell membrane to then be evenly distributed throughout the object.
