Explain what the white light and the symptoms of dying are. The link is on slide 20 there’s there are hallmark features when people pass these stages that they transition through. use the below link (ONLY) for reference to write this article. Also attached are slides for this purpose.
Near-death experiences are ‘electrical surge in dying brain==>https://www.bbc.com/news/science-environment-23672150
Label six test tubes / boiling tubes with the concentration of Sucrose solution to be used.
Fill the tubes with 10 ml of the prepared sucrose solution at the correct concentration. 3.Cut 6 potato pieces to the size secified and dry them on a paper towel 4.Weigh the potato pieces using a balance and record masses in an appropriately designed table.
Place potato pieces in a beaker/ boiling tube. The solutions should completely cover the chips.
Leave for 30 minutes.
Remove potato pieces one at a time from the beakers/ boiling tubes. 8. Dry the potato pieces on paper towel.
Calculate the change in mass and the percentage change in mass of each set of potato pieces.
Plot percentage change in mass (y-axis) against concentration of Sucrose solution (x axis).
Calculate the percentage change in mass using the formula below:
% change in mass = final mass – initial mass x 100%
Initial mass
Where there is no net gain or loss in mass, ψCELL is equal to ψBATHING SOLUTION. From your graph read the molarity of sucrose where the percentage mass change is zero. 15. From the table below, find the water potential of a sucrose solution of that molarity
Identify the basic requirements of life and the properties of the major molecules needed for life.
Describe the relationship between structure and function in organisms using biological examples.
Identify the structure and function of the key chemical (functional) groups that affect the function of biological molecules.
Identify the principles of inheritance and solve classical genetic problems.
Discuss what comprises the cell’s genetic material using the terms chromatin, chromosomes, and sister chromatids and how this genetic material is organized in the dividing vs. non-dividing cell.
Describe how homologous chromosomes are similar and how they can differ.
Identify the chemical structures, synthesis, and regulation of nucleic acids and proteins.
Describe DNA and the difference between chromosomes, chromatin, and genes.
Discuss how one chromosome (for instance, Chromosome 1) inherited from your mother is similar to the same chromosome inherited from your father. How are they different? Finally, share how this impacts your view of how your DNA vs. your environment affects you.
