preparation of reagents
This interactive is not working. I used it earlier this week and it was fine. Also, I downloaded it and it works fine as a download, but I would like my students to access this via the internet. Is there someone why can take a look at it. It seems like the start button may just be covered up.
Your interactive only works up to page 4 then shuts down. Is there a fix??? I really enjoy this interactive and use it with my students in biology class?
I have forwarded this error on to our developers. Thank you for pointing it out to us.
If the learning object is not working correctly for you, it is usually because you are viewing it on an outdated browser such as Internet Explorer 9 or older.
why is the cell membrane considered semi-permeable? explain
Semi-permeable means "allowing certain substances to pass through it but not others, especially allowing the passage of a solvent but not of certain solutes." The cell membrane allows some things to pass through, and not others, which is why it needs transport proteins to let the other things through that the cell needs.
Why does the cell membrane have transport proteins ?
channel proteins help molecules across the membrane via passive transport, a process called facilitated diffusion. These channel proteins are responsible for bringing in ions and other small molecules into the cell. ... The other type of transport protein is called a carrier protein.
can someone tell me
how am i able to download this?
Downloading a learning object.
To download a learning object simply click the "Download a Copy" link located underneath the title of the object. You will then be directed to a download page where you will click the BLUE "Download" button at the bottom of the page.
To view the learning object, right click on the file to unzip or extract the files from the folder and then click on the .html file to play the animation in your browser.
As I go through the interactive component, I can view some of the images to select, but not all. It seems to be only the glycoprotein that is visible.
Many of our older learning objects were built with Flash which is no longer supported by many browsers. I can view it on my PC using Chrome. If the learning object is not working correctly for you, it is usually because you are viewing it on an outdated browser such as Internet Explorer 9 or older. We are in the process of rebuilding many of these older learning objects.
This may be a good alternative:
Outstanding! I hope more is on the way?Posted by Ed Johnson on 1/18/2006 12:00:00 AM Reply
Excellent work. My 4th grader is studing cells in school and this will be a great learning tool for her and it was fun also. We need more people like you that care.Posted by barbara fields on 9/30/2008 12:00:00 AM Reply
I like the graphics which have been used in it and it is full or information. I would suggest every one to try.Posted by Liaquat Ali Bhutto on 7/17/2008 12:00:00 AM Reply
At first I was very nervous about using a website to learn about the cell membrane. I was very scared and didnt want to use it. Like many of you, I didnt want to receive false information. However my teacher strongly recommended this website to me. Ever since, I use it daily for study purposes. I recently got a hundred on my test! Thank you guys for changing me from a website fearing boy to a website using man! I will use you in the future! I hope to learn about subatomic particles in the future!Posted by Logan Connolly on 10/30/2013 11:13:47 AM Reply
