Registrace 18. 09. 2013
Professor | CZcamsr | Investor | Shadetree Mechanic.
I have earned my Ph.D. in Genetics and completed two postdoctoral fellowships conducting biomedical research. I'm now a full time community college professor and CZcamsr. :)
On this channel, I will: explain concepts covering (but not limited to) biology, give life advice, post reviews, and hold office hours for students. I hope this channel can be used by not only my own awesome students, but students around the world!
Thank you for joining me!

Those are not return springs. They are anti-rattle springs, and you don’t need a special tool to put them in. Just use pliers so you can see what you are doing.
Isn’t that supposed to be net atp 38
Where can I get the grommet for the aluminum radiator. I purchased a new aluminum radiator and the hole for the fan switch is larger than the stock radiator?
Fire video
This is a fascinating chapter. I encourage all new students watching this to get immersed and understand it. When I was a student that was my philosophy: If you understand it, you will remember it.
Snap on is worth it… I bought an icon ball hex set recently while working on 5mm Allen fastener on a gsxr750 and the ball end sheared clean off when I went to snug the bolt down…… moral of story it left me stranded had to drive to harbor freight luckily they are open 7 days a week to warranty their junk. Will others work? Yes. But how many times they will work will be a lot less than snapon and that’s simply in the quality of the steel and that’s why you’re paying more for the snap on. I love all tools o try them all I like to own them all. But snap on seems to always surpass my others.
Congratulations🎉 ❤
Thank you for this amazing video❤
THANK YOU VERY MUCH this video has save my butt from spending hours to read campbell lol 😓 THANK YOU DR. D‼️
I graduated from General Science back in 2007 and then made a PharmD. From all the years of study I will always remember Campbell Biology as one of the best experiences in my student life.
You probably should spend your last 500 on a bankruptcy logger
Thank you for your genuine love for teaching and biology! Please keeping making more of these! Thank you for your time and efforts!
Thank you Doc!❤
Thank you
Such an amazing teacher, so helpful!!!!!!
Nice tools, go towards impact tools. Also don't worry about the negative comments about buying snap on tools. May God bless you in the automotive industry.
Such an amazing teacher thank you!!!
Doesn't the toxin denature when heated in normal cooking?
Thank you so much. I love the way you teach and your cats’ appearances.
thats some rusty mgb has it been in the river?
In Australia (home of no white Australians) that amount of money would get 1/4 the amount of items…. Immigration has ruined us. 1 litre milk = $3 in 2024
pawsitive 😹
Does this video includes all the main points to study for the Ap bio exam? For chapter 1
great content and very detailed explanations! please do chapter 15 as well
love it dr
Tekton sell that socket but for $6.
can we get an update on this and how it went? also just because you can doesnt mean you should.
Incredible! Thank you, Sir. I am currently going through each chapter !
Let’s goooooo
Thank you. Off to watch the one on PH next.
You’re so welcome!
❤❤❤thanks
You’re so welcome and thank you so much for your kind words and support!! 🫶🏻
Super helpful! And the Radioactive Man comic on the board made me 😊
And now I have arrived at the conclusion that the cost of an auto tech class at my local community college will be more than covered by the discount 😂
I never usually comment, but your content has saved my life in Biology! Thank you for what you do!
Thanks a lot, I'm beginning to get a clear understanding. This will really help with my genetics lectures 😄
Vinegar and salt cheap rust remover leaves it like new.
Thank you for providing us with this lecture, it was quite useful and helpful as of now still in 2024!
DR. D is uppppppp
Once again you've worked your magik on your explanation of another cellular energetics (masterclass)😤
I had difficulty removing the round head bolt of the wheel cylinder. What was the size of flare nut wrench did you use?
Congratulations 🎉 🎉....we're looking forward to the content.
Please, I need the power point which you explain on it
DR D!!! I NEED YOUR HELP WITH MORE CHAPTERS FOR THE INFECTIOUS DISEASES ON MICROBIOLOGY AND PARASITOLOGY 😭😭😭
Where on earth can I buy the tensioner bolt that holds the tensioner bracket in position??
youre literally so helpful, i watched your carboxyl functinoal group explanation and it was so helpful
You’re so welcome!!
❤❤❤❤
Dr. D, where did you get the master cylinder bleeder kit? I’m looking for one and they are all made for two ports.
I may have had to buy two kits if I remember correctly. 😕
13:52 Are immune cells transferred from a healthy to a sick person? After this piece of the video the artificial passive immunity with transfer of antiserum is discussed but heard nothing about transfer of immune cells. Is this something that happens? I imagine it being a foreign cell to the body that gets killed like what happens with transplantation.
This is Awesome!
You are single-handedly saving our university class with your videos. Thank you so much for your work!
