Hi! This lesson is really interesting and is it possible for me to ask a few questions? -I was wondering, how does these lancelets eat and what do they eat? are they classified as omnivores, herbivores, or both? -Do lancelets possess scales? At a glance, they look like they have a really smooth skin! -Are they classified to be symmetrical bilaterally? -Lastly, if ever they don't have scales, do they process slimy skin? I hope you can answer my queries as you video presentation really helped me with my studies! Thank you
Hi! They are already in the description! If you scroll to the bottom of the description, under where it says the channel name, it has a shortcut and preview of all TH-cam videos linked in the video you watched.
@ProfessorNewtoff oh, I see now, thx. I watched your videos for the exam and I can say that your videos allowed me to understand each taxon and phyla easily.
It's the other way around, plant cells have a cell wall, but not animal cells. The cell wall is a way to provide structure to plants (making them upright). However, animals have various proteins, tissues (such as cartilage and bones), chitin, and more than also provide that structure, so it's not necessary for animal cells to have a cell wall. Also, animals move, and a cell wall would make it too rigid to do so.
So the notocord is the precursor of the vertebral column (your backbone). Think of it as structural support. However, the nerve cord is your spinal cord. This is the message relay center, sending signals throughout your body.
It's not necessarily a cause and effect in that way, it's more of "there is a diversity of organisms, therefore there is a diversity of DNA (which also means a diversity in genes)". There is a diversity of organisms because there is a diversity in environments and organisms will adapt to those independent niches.
Thank you so much for this video! It really helped me understand better and I'm so glad I came across this video!
Thank you so much for the video❤❤
Carry on making videos they are much helpful to me and you are very good
Well explained! Great job!

It would be much easier to us if you put the links in the description of the video.

hi mom! 🤗
Thank you so much
Is there a reason why animal cells have a cell wall but plants don't? What do you think?
It's the other way around, plant cells have a cell wall, but not animal cells. The cell wall is a way to provide structure to plants (making them upright). However, animals have various proteins, tissues (such as cartilage and bones), chitin, and more than also provide that structure, so it's not necessary for animal cells to have a cell wall.

Thank you really helpful for studying for the science bee I got today
Thank you ma
There are some pretty big cephalopods out there
Man, imagine 100,000 years ago! Out current cephalopods have nothing on today's ones!
What is the difference between notochord and nerve cord in humans to be specific?
So the notocord is the precursor of the vertebral column (your backbone). Think of it as structural support. However, the nerve cord is your spinal cord. This is the message relay center, sending signals throughout your body.
Thank you. For you explainig . I uderstand well
Thank you professor, it is brief, clear and informative
THANK YOUUUUUUU
Thank you for this video ! it was extremely informative and helped me sooooo much with my geology assignment 😊
Is the diversity of animals and other organisms due to DNA (Nucleic acid) and the diversity of genes?
It's not necessarily a cause and effect in that way, it's more of "there is a diversity of organisms, therefore there is a diversity of DNA (which also means a diversity in genes)". There is a diversity of organisms because there is a diversity in environments and organisms will adapt to those independent niches.
don't seach up humans with tails
You searched up humans with tails didn't you?
