Explanation:

Lab: Reactions  

The goal of this lab is to demonstrate the effects of changing temperature and particle size on the rate of a chemical reaction. The purpose of this lab is to plan and perform controlled tests of multiple variables using repeated trials during an investigation about reaction rate. This is an inquiry lab. My hypothesis is that the effects of the different variables will have a major effect on the outcome of the results. The temperature will change dramatically by the multiple factors it will be exposed to. The different variables include the substance in the container, the temperature in the container. Also, the temperature of the room can affect the ending temperature of the cylinder after the experiment. The controlled variables are using the same thermometer and the amount of substance put into the vial.  

 

The materials needed for the lab are listed above. The steps of the experiment do not change, only the substances used for the experiments. This includes started with the beaker and filling it with the cylinder with water. Then you use the thermometer to check the degree of the water. Then you use togs and place the beaker filled with water onto the hot plate. You turn on the hot plate and wait for the water to heat up for 5 minutes. Then you use togs and remove the beaker from the hot plate and turn the plate off. Then you use the thermometer and check the temperature of the heated water. You put the tablet into the heated water and time it. You repeat this process with all of the substances.  

You should record all of the processes of the lab and write it all down.  

Table A: Baseline Data for Tablet in Room Temperature Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 50 50 Trial #2 250 20 0 52 52 Trial #3 250 20 0 51 51 Average Time for Tablet to Dissolve 51 Table B: Time to Dissolve Tablet in Hot Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 40 0 22 22 Trial #2 250 40 0 24 24 Trial #3 250 40 0 20 20 Average Time for Tablet to Dissolve 22 Table C: Time to Dissolve Tablet in Cold Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 4 0 84 84 Trial #2 250 4 0 89 89 Trial #3 250 4 0 85 85 Average Time for Tablet to Dissolve 86 Table D: Time to Dissolve Tablet When Quartered Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 41 41 Trial #2 250 20 0 44 44 Trial #3 250 20 0 41 41 Average Time for Tablet to Dissolve 42 Table E: Time to Dissolve Tablet When Crushed Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 18 18 Trial #2 250 20 0 18 18 Trial #3 250 20 0 15 15 Average Time for Tablet to Dissolve 17 Summary Tables Table F: Summary Table for the Effect of Temperature Volume (mL) Temp. ( oC) Average Time (s) Hot water 250 40 22 Room temperature 250 20 51 Cold water 250 4 86 Table G: Summary Table for the Effect of Surface Area Volume (mL) Temp. ( oC) Average Time (s) Tablet form 250 20 51 Quartered 250 20 42 Crushed 250 20 17

The different substances used in the experiment reacted differently based on the heated water and conditions of the outside temperature. This was affected by all of the variables. I did not do any background research before doing this experiment so I do not have any prior experience on this topic. My hypothesis was correct after conducting the experiment. This constantly changed based on the variables and substance used.

Describe the function of stem cells in glands and in the epithelium of the skin
IrinaK [193]
Epithelial tissues undergo turn-over throughout adult life: cells die and are replaced. Consequently,most if not all epithelia contain stem cells that 
<span>(i) are competent for cell division, </span>
<span>(ii) self renew:regeneration of a "mother" stem cell with each division, and </span>
(iii) produce differentiated cell types specific to each epithelia.
-Stem cells produce differentiated cell types by cell division coupled with specific pathways of cell specification imposed on some of their daughter cells. In most stem cell-tissue systems, cell division and specification goes through several steps. Many stem cells produce daughters that also proliferate themselves (undergo cell division cycles), often at faster rates; these transitional intermediates are called transit amplifying cells. These transit amplifying cells then produce differentiated cells, either directly or through several steps of specification. At each step,specific changes in protein expression patterns and activities occur.
-Stem cell in gland crypt bottom (tightly control stem cell, have to divide longutdinal)
<span>-Stem cell in skin basal lamina (divide in apical direction (change in phenotype) form squamous layer at apical, highly control (reactivate/reuse), secrete ligand that core signaling molecule (WINKS) in early develop than reuse and reactivate for stem cell in skin... also use in cancer cell (lost of control=tumor))</span>
