In an isotonic solution, there is no net movement and there is an equal concentration of solutes and water.The dialysis tube represented the cell membrane to act as selectively permeable to water and some solutes.Osmosis is specifically the movement of water through membranes.When water diffuses into the cell, this causes the cell to be enlarged.The hypertonic solution has a higher solute concentration and lower water potential.

* Place the bags into their corresponding beakers and fill the beakers with distilled water enough that the dialysis tubing is completely submerged in the distilled water.I have concluded that my hypothesis was correct, since the date reinforces that the mass is greater after being put into the beakers of distilled water.Run the bag under water for just a moment.The independent variables in this lab are the beakers of distilled water, and the amount of sucrose (0.2-1.0M).More errors could be not covering the bags completely with distilled water or not leaving the bags in the beakers for exactly 30 minutes.

Four problems faced by animals on land are breathing (respiration), water conservation in excretions, successful reproduction, and the producing an egg which can survive outside of the water.Inside the gills of aquatic animals, the circulatory system removes oxygen, and delivers waste carbon dioxide.Aquatic animals use gills, which are outgrowths from the body which increase surface area over which gas exchange can occur.For each problem, explain a physiological of structural solution.Terrestrial vertebrates have developed lungs to solve this problem.

When the gills are open water is allowed into the respiratory system.Gills can absorb 80 to 90 percent of oxygen from water, but use 25 percent of the organisms energy.This may sound like gills extract a high amount of oxygen, but when you compare water and air with the same volume, you will find that water has 3 percent of the oxygen that is in air.(air as more oxygen than water does) Lungs need 1 to 2 percent of the energy in an organism, while gills need 25 percent.Fish obtain water and oxygen though their gills.

I was not looking forward to this part of the class; I was even considering transferring into the normal, calm Biology class every one of my sane friends had done, but it was too late to turn back now.I told them that they would have to do a lot more of the answering questions on the worksheet this time if they wanted any help from me.What helps me through is thinking back to my Biology class and then I calm down long enough to watch an open heart surgery (for 5 seconds).After all, this is Biology and some of you might want to become doctors.Anytime I freak out about the disgusting stuff in our world I think back to that one day in Biology class when I was the doctor for that 1 hour and 45 minutes.

Hypotonic is when the solution has a lower solute concentration compared to the water potential.In the inquiry, I predicted that the blue solution was water and that it would have an isotonic environment, meaning there would be no percent change.I first cut the potatoes into 6 cylinders of the same size by using a cork.When water diffuses into the cell, this causes the cell to be enlarged.This occurred because the tubings were placed in a beaker of water.The materials used in this procedure were beakers, water, sucrose, glucose, NaCl, ovalbumin, 20 cm-long dialysis tubing and balances.

We then put Carrot 1 into the water, while Carrot B went into the salted water.The data from the beaker had also changed, the color had stayed the same, but the glucose present had changed, because in the beginning the beaker didn’t have any glucose, but now the distilled water had some.Carrot 1 had gone through hypotonic osmosis, where the water goes through the cell membrane.In this lab hypertonic osmosis had taken place, because the salt from the salt water had brought the natural waters out of the leaf, and before you knew it the leaf under the microscope was much smaller.We knew that the glucose from the dialysis bag, had come out and into the beaker, and we knew that it had to be through diffusion because it wasn’t just water in th...

Not knowing about your colleagues and their entertainment and food preferences could create unnecessary problems.To which I replied, “I am taking AP Calculus”.There are many changes that can be brought to the community and school that would be very beneficial.But if I had the power to change three things in my school or community, I would obligate all high school students to take a culture and religion class, encourage students to take higher level academic classes instead of just the basics, and I would encourage hosting more community activities.But with our small community size and our extremely diverse population, we could host annual picnics where people bring traditional dishes, stage a mixture of cultural performances, and, overal...

In Canada, buildings consume about one-third of total energy used, two-thirds of electricity and one-eighth of water resources, in addition to transforming the land that provides valuable ecological resources.Next, the LEED system evaluates each phase of each project based on 6 main categories for which credits are granted (the number of points depends on the benchmark used): - Ecological site development (21 at 28 points) - Efficient water management (10 to 11 points) - Energy and atmosphere (33 to 37 points) - Materials and resources (13 to 14 points) - Quality of indoor environments (12 to 17 points) - Innovation and design process (5 points + 1 point if there is a LEED professional) - Regional credits (4 points) Thus, each project is...

Of the female students who have been enrolled in an AP science course, 89% feel like they have a lot of success in science and 78% of them feel these courses to help with their future career choice, yet even though they believe their teachers have made the science exciting, all of them believe the school lacks the opportunities for pursuing science related fields.The difference between the female students in AP courses and those who are not, those students have a different outlook on how they feel regarding being successful.The next step would be working with the science teachers to come up with ways we can support and increase the interest in science for female students at all levels in high school to have them want to continue even aft...

However, it is also about students having the motivation to learn.Students in these cultures and part of the low income society have to get out of the mindset of being part of the cycle of failure.They may have to break from the typical stereotypes, but that doesn’t change where they come from.They understood the culture so they knew how to teach the students in a way that would help them stay interested in learning.Being that I am a nursing major and not a tutoring type I was kind of nervous about participating in this opportunity, however, I was able to join the biology class which felt a little more like home.

At the Lab Schools\, the debate intensified last spring when Tom Stanley-Becker, a junior taking AP U.S. history, stated himself an “AP Dropout” in a Los Angeles Times column.She took four AP classes and six AP tests during high school.As a student who took two AP classes during high school I felt it was a struggle to keep up with my other classes because I was too focused on my AP courses.Debra Shaver, director of admission at Smith College, understands the annoyance that some AP teachers have, but she says that “you may be doing students a disservice by dropping the AP program, if you are not a Scarsdale or Exeter,”.“It was just not the happiest time.” After she was accepted to Dartmouth College, the school told her the 4 she got on he...
