Hello! I'm DrWD40 and welcome to my classroom! I have my PhD in Biological Sciences & BSc in Astrobiology. I am a biology, anatomy/physiology, genetics, immunology, and microbiology college instructor. My PhD research focused on diffusion & bulk flow in relation to neuronal function in Alzheimer's disease. My specialties are protein biochemistry, biophysics, neuroscience, anatomy & physiology and general biology. I have a passion for teaching, science communication, making educational content open and available to all, and sometimes dabble in video games. I decided to start streaming and making videos to share my love of science with the world. Hope you enjoy the content and learn a thing or two!
I am also a cofounder of a community called The Knowledge Fellowship (TKF). We are a group of people seeking to share educational content on Twitch and other social media platforms. Feel free to check us out!

From Zygote to Genetics: Understanding Early Development and Inheritance Patterns
In this enlightening video, we embark on a journey from the very start of human life, exploring the early stages of embryonic development, to unraveling the complexities of Mendelian genetics and common genetic abnormalities. If you've ever pondered how a single fertilized egg evolves into a complex organism or how traits are passed from parents to offspring, you're in for a treat.
We begin with the fascinating process of fertilization, where a sperm and an egg unite to form a zygote, setting the stage for the development of a new life. Through the divisions from a two-cell stage to a morula and eventually to a blastocyst, we'll delve into the critical steps leading to implantation in the uterine wall.
Shifting gears, we then introduce the principles of Mendelian genetics, paying homage to Gregor Mendel, the father of modern genetics. Through simple explanations and examples, we'll cover the basics of alleles, dominant and recessive traits, and how these principles apply to monohybrid and dihybrid crosses. This section illuminates the patterns of inheritance and the probability of certain traits appearing in offspring.
Additionally, we'll discuss some common genetic abnormalities, including Down syndrome, Klinefelter's syndrome, and Turner's syndrome, providing insights into how chromosomal variations can lead to these conditions.
Whether you're a student needing to grasp these concepts for your studies, a teacher looking for resources, or simply a curious mind eager to learn about the marvels of human development and genetics, this video offers a comprehensive overview in an accessible format.
Join us as we connect the dots from the microscopic beginnings of life to the genetic blueprints that shape our being. Dive into the comments section with your thoughts, questions, or topics you'd like us to cover next. Let's explore the wonders of biology together!

If you have the money I’ve found they have a pneumatic nail remover, like a bolt gun that shoots it though and out and a nail puller. Sadly the puller is way more expensive. But a great thing if you have back and knee issues to cut down on bending.
Heard of those. They're pretty cool!
Glad you met Terry Shannon. I have 3 of his books. Turf to Surf, Detecting the Treasure coast and Metal Detecting the Ottertail. When I finish these, I will get the 4th one. Keep swinging!
Absolutely amazing video!! Everything was broken down in a much simpler easier fun way to learn!! Thank you 🙌🏽✨
Thanks! I completed a more introductory series for anatomy that may be of additional help for you. czcams.com/play/PLddaXzcsfB5Xix5SAoUPS-vPmY8YDOS5s.html

One thing we should consider:Are twin exactly identical on a genetic level or do they have small differences? searching about this some sources claims that twins have 0.02 genetic differences other ones said is 0, taking into account that the separation between humans and some other animals is lesser than 0.8 it can't be said that is a trivial thing
I need a link to magnet 🧲

thanks for the ideas

You did a time lapse on tearing the pallet down , it would be nice if you said approximately how long it took to break it down.
About 10-15 minutes
Incredible shot❤

I'm glad you enjoyed it! Thanks for all the 👍🏻 comments too!

Reusable rocket science.
Hopefully they paid up the carbon offset credits to negate this carbon😂😂😂
Why are people so amused by this 🤷♂️ they did all of this in the 1960's when went to the moon 🤷♂️🤦♂️🤣
It didn't land without assistance back then
Oh wow I must have missed the Saturn V landing
The tower of babbel for our age. It will end with the same fate.
Dam! There Goes the Ozone layer!😮
That's a wicked shot you got!! Well done!
increadable!

Aaaannnnd, thats how you produce more hazardous emmissions in 60 seconds than all our passanger vehicles with internal combustion engines in the state of Washington, DC in a year....🤔
Dense comment
well over 5000 commercial flights every single day burning kerosene butttttttttt one rocket on one day burning kerosene is a problem? grow up man
So what, it is progress and even you benefit from science like this
Exactly my first thought .
Do flat earthers just pee themselves watching this?
Did you see the rocket go to outer space or just under the atmosphere? Why did the rocket go at an angle instead of straight up though it?
@@mysticmadman5961You're thinking. And that's good. But I'll suppose you have a brain at least slightly fuller that a toddler's. Earth is round. You launch then aim for the horizon if you're goal is to use earth gravity assist or if you wanna stay in orbit. Learn physics and grow up
Wow, that was incredibly awesome footage!! Thanks!
Glad you enjoyed it!
Hahaha looks like a cock and balls 😂😂😂
How does that affect the ozone layer?
I believe the effect is relatively small compared to chlorofluorocarbon emissions, but it’s definitely an important thing to consider seeing the launch frequency increase substantially.
Oh, man. So cool. I just love me some science fiction.😮
The Ozone Layer was a HOAX perpetrated in the 80s by the Right Guard Cartel in an attempt to put the Rustoleum Mafia Empire out of business.
The same way an ant's far affects your daily life.

Nice. Quick questions: 1. How is it holding up three years after this build? 2. I'm thinking of maybe going two-feet off the ground to increase the head pressure. Do you think that makes it too prone to tip? 3. How did you locate the notches in the center of the cross pieces? Thanks. dp
I moved from that place last August and it was still holding up great. I actually hooked some drip irrigation lines into the facet for easier watering. Head pressure wasn't the greatest so maybe your idea could help there. They were slow drip lines so I didn't mind. I didn't feel any risk of tipping. If you have enough support, it should be fine. If you're worried you could add some concrete supports to the base. As for the notches, if I recall, I just measured the midpoint, overlayed the pieces, and outlined the edges for where i wanted it. Depth was just half of the 4x4 so that the cross would be flat.
@@DrWD40 The drip irrigation line was a nice touch. Did you do a video of that? I just built a 3X6 raised bed garden. I want to put the barrel next to it. It might be fun to measure how much I water it from the barrel and how much produce I harvest in a season. I'd like to rotate several crops in a season to see if I can produce much within the same 18 square foot space.
I finally did this and I am pleased with the result. I made a few adjustments. My uprights are three feet tall and I located the barrel shelf two feet off the ground. I wanted a little more height to reach some elevated beds elsewhere in the yard with a hose. I had a little trouble cutting the right depth for the lap joints. I was afraid of cutting them too deeply, but had to cut them again to get them deep enough. They still aren't perfect, but I think the next time I'd be better at doing them. Thanks for the nice design.
