Mr Anderson is simply the best! I really understand & will remember these online lessons, seriously grateful for your time in putting this together online, God bless you!
I am a teacher and thinking of making video for my middle school students. I am curious how long it takes you to create one and if your district is supporting you in any way with time or money to do this? If you have information posted anywhere about the hardware, software and process you use, I would appreciate a link.
Mr D science don't know how helpful this is three years later, but I may as well put this here for others who are wondering. Videos like this can be made on practically any computer, though I am uncertain about Mac compatibility. To be able to write on the screen, you can look into a touchscreen laptop or a wireless mouse that can "draw" in midair via pointing mouse at screen and holding a button. One program that I'm aware of and have used is an add on for PowerPoint which allows one to have a face cam, pictures, and the ability to draw over your presentation all while recording your screen, face, and audio.
Mr. Andersen, are you currently involved in any research? If so, can you provide us an abstract of your research. If not, you should definitely consider it.
So please help me understand. This guys says at 5 weeks there is no difference between a boy and a girl, but at 6 weeks the "testes" start to producing a transcription factor called an SRY gene or the sex determining region of the Y. Then he goes on to say that we are all female until the transcription factor completes the process of becoming male or female. Yet before that he says there is no difference between the 2 at 5 weeks. So shouldn't that mean the embryo is Neither male Nor female until the "testes" start to produce the SRY gene? By testes I'm wondering if they become either testes or ovaries upon completion of the process. Either way that doesn't justify saying that all embryos are at some point female.
I feel stupid because I almost understand it except for one or two things. How does that first liver cell or neuron come to be. I can kind of understand how one liver cell can turn into a whole liver. Its that first one that troubles me and how do your organs get where they are, after all your heart is toards your left and livers, spleens have a decided side they always develop towards. I should explain that im not a student or medical professional but a retired application developer and systems analyst with too much time on my hands.
Cells are hugely complex after near 4 thousand million years of evolution. This means that they have had massive time to vary through changes. Evolution works through small changes. When a small change happens to be more useful than other changes, it is favored by the increased "fitness" of itself, or for the organism of which it's a part. Fitness, then is advantage in the present, usually defined as ability to increase its number of offspring over alternatives. In order to answer the varying positioning and nature of cells, the somewhat simpler action of chemical bonds must be understood. Chemistry can lead you to understand organic or carbon chemistry. Those basic issues such as polarity are of extreme importance. Genes happen to code for specific fits of polymers. Because of the differences in electrical charges, bonds can be created through breaking or synthesizing connections. Proteins, due to varying polarity, can fold in different ways. So some of those ways are more advantageous than others. Advantage would be in creating a better complex structure, allowing persistence and specific relation with another chemical structure. So, variations in proteins or ability to use energy can make a slight change lead to proliferation of the cell in nature. Large organisms depend upon this. As an engineer, you can see the utility of variable ductility , strength (tensile, etc), energy absorption. So, to most easily understand how Cells are able to differentiate, you must begin with chemistry, organic chemistry, cellular biology, evolutionary cellular biology. There are texts available easily at any used book store near a university. Most of us began early in school with these subjects. When you understand the basic texts you will have the vocabulary and logic for the rest. Just as an aaside, I note in Science mag recently the discovery of cells that have the genetically-tuned ability to create energy without having the symbiotic organelle mitochondrion within. The ways in which cells transfer information (as Batesons defined - "any difference that makes a difference") are many. Some transfer genetic material to other cells, create replicas, or do the simpler 1/2 replication called meiosis. You will have to return to basic biology texts to understand the architecture of the process. It's pretty absorbing, and should you have a background in the mathematics of motion, change and complexity, you will have a bridge to the chemistry involved, as well as intuition about optimality, suboptimality, and dynamics. It will really assist in understanding evolution as well as ecosystems. It will even give insight into behavior, which is also shaped more through evolution than has been understood to this point. Welcome to the land of the living!.
+george mira thank you for your answer. i understand it when im reading it but im lacking the ability to explain it to anyone else. i had organic chemistry in college and teenendous programming and object oriented methodology which oddly lends itself to biology.
i been looking at the movie Dr Death this is a better way for me i been trying to find ot how my heart works i only have 25% of heart rate need more informaton

Thank you for taking the time to share your knowledge. it really helps me to understand complicated topics.
Everything makes so much sense now. Thank you, this is an incredibly helpful video.
I used you all throughout year 12! I'm now a second year Science Uni student and I'm so happy you can help me again :)
You are such a better instructor than mine! Just wanted to say thanks for these videos! I subscribed because you explain these way better.
This is so great. Thank you! Have my anatomyexam soon and this helped me so much!

"And so if I were to ORGANize this podcast."
Amazing. Thanks for making this video.
You've earned a subscriber
Cramming tip: listen to it in double time. *so desperate*
"That's gonna turn genes on, and turn teens-genes off!"
Lmfao
How school appropriate.

Are the things your teaching about causes in the making of Yellowstone park? 🍎☮️
Mr. Anderson is the best!~!
this was helpful. Thanks!
This gave me homework you bad boy
lol
Your pic is trash kid
anyone got the answers to the worksheet?
ya i gotchu
so amazing !!
waiting for new videos
thx a lot
what software was it that you used to screen-cast this video? Camtasia Studio 8? thanks
Man!you are amaziiiiiiing
Paul for President
Brilliant video, thank you
Great video !!!

can someone summarize this please
cells
I just had a test on this!
In the pluripotent state, if those cells were to divide into two groups that would also result in identical twins, no?
Anderson I love UUUUUU!!!!!!!!!!!!!!!!
Sry is carried on the Y chromosome and not produced by the testes, its the Sox9 that is produced.
very nice
So please help me understand. This guys says at 5 weeks there is no difference between a boy and a girl, but at 6 weeks the "testes" start to producing a transcription factor called an SRY gene or the sex determining region of the Y.

By testes I'm wondering if they become either testes or ovaries upon completion of the process. Either way that doesn't justify saying that all embryos are at some point female.
You're basically female by default and SRY production triggered by Y Chromosome makes you male.
my teacher sucks
Great video thanks :)

Thus gave me homework you meane
This*
it wasnt
11 years and nothing changed xd
only two comments on a bozmean vidoe? da fuq?
I like the videos but it irritates me how he calls himself Mr Anderson on youtube. Paul will do just fine mate
He calls himself Mr. Anderson because he is posting them for his students.
yeah james
white station
what
