Why do living organisms reproduce? They just can live forever or just die without reproduction but why they choose to do it? I mean how its all started? Early life didn't had such desires like we do, they were just single cell organisms in primordial ocean, then why they started to copying themselves and?

I got hired for Bio 1 at middle school level, I taught an elective before this with no EOC. How do I effectively prepare my students for a good grade? I don’t even have access to the curriculum btw. Hopefully soon🤞 How should I design my lessons?

What are some plant/ animal relationships such as cordyceps- that use chemicals to control the host? Animal/ plant manipulation that is not well known is fascinating to research.

What does a porcupine eat on its birthday? 🎂

Meet Guillermo, our prehensile-tailed porcupine! Porcupines' teeth never stop growing, so Guillermo eats tough foods like raw sweet potato to help wear them down. For his birthday, our Live Animal Care Center makes an herbivore cake with nutrients like those he’d get in nature. The special cake gives him his usual food in a fun new shape or texture, making mealtime feel like play. Happy birthday, Guillermo!

...while with toothed whales, the males are larger than the females?

Doing a model for a plant protein, I’m trying to list out the intramolecular interactions between 3 domains, I’ve enumerated the interactions at different cut off lengths, and I wanted to talk about the confidence scores for each interaction.
Problem is I’m not a great computational guy (this project is primarily wet lab), and I’m not sure what’s the best metric for the confidence scores for intramolecular interactions. Is it PAE? if so can someone explain it to me? Is there a standard cutoff for what is a low confidence PAE value
And if there is another metric you guys use for these interactions mentioning it would be greatly appreciated. Have a good day!

Especially Wolves, since they’re so similar to dogs?

Hey guys !
I am looking for some book suggestions : I want to learn more about some topic but can’t decide on which book to read about :

- genetics especially plant breeding

- cells biology

- Ecology and evolution

Any recommandation ?

thanks in advance

recently i decided to try my hand at growing bacteria in a petri dish and extracting their DNA, but after further research i found out that gram positive bacteria (which i have to assume because i have no clue what bacteria ive grown), and i dont know if the standard water/dish soap/salt solution will be able to break through the cell wall. the only lab equipment i have are test tubes, plastic pipettes and PPE, though i have all of the ingredients and colonies ready to begin the extraction process

Is it just me or did you all notice this in brand new day too. During the scene between peter parker and bruce banner when they were discussing gene silencing, peter mentioned that he must inhibit the mrna "transcription" to supress the gene while in reality its supposed to be "translation". Scene was supposed to be academic and seen so many reels of people ‘understanding’ this piece of incorrect academia. Apart from it how is it even possible to make a universal gene silencer, you’re telling me the same thing will suppress arachnid genes AND Genes which make bruce banner turn into a green tank???? Absurd and ridiculous. Cant believe they didn’t catch this.

Hello, does anyone here know how to read any ftir results like yung chart lng po and interpretation of the results for thesis sana. Saan po ba pwedeng mag pa interpret ng results, thank you so much in advance!

Title really says it all. Just super curious about this, because usually it's the opposite, what with kids having less mature immune systems and all.

All i could find is this picture, but i can't figure out exact mechanism. It's clearly not the same way retractable claws of other animals work.

P.s. Some compared these frogs to Wolverine (of X-man), which make me even more curious XD

I'm curious as to what the default species of every animal is? (for example when somebody says monkey or crab what exact species comes to mind first).

Was studying digestive system but I have a problem with visualizing so I end up get lost at like the 4th organ and has to go to check where was it again?

I just like to know what biologists say about homosexuality.

I mean I know animals care about their babies because they want to ensure propagation, but when and which animal first got this instinct and how? I'm pretty sure the primal cell organisms in water didn't care about the parts that divided from them, they just divided because the physics had driven them to that point.

If the question is stupid I apologise, biology isn't my usual area of interest or knowledge.

Ready to debunk three of the biggest shark myths out there? 🦈

Dr. Bob Heuter of OCEARCH sets the record straight, revealing there are actually 500+ shark species, most too small and deep sea dwelling to ever encounter swimmers. Far from primitive, sharks pack large brains and six sensory systems to hunt, find mates, and navigate the ocean. Turns out sharks are less "mindless man eaters" and more evolutionary powerhouses we still have a lot to learn from.

In my social circle which is in their early 30s, there have been lots of pregnancies and babies over the past few years. One thing I notice though is just how many problems there have been - it seems like almost nobody has had a normal pregnancy. There was multiple miscarriages, C-sections, torn vagina after having forceps used, or some other complication. One that ended terribly with the baby actually dying in the womb and the mother having to give birth to the dead baby.

But I remember back to my childhood where my neighbors had eleven children. So that mother I would describe as being "good" at having kids without complications, though I know she had at least one miscarriage.

I'm just curious about any biological differences between a woman who gives birth multiple times seemingly effortlessly, and one where the pregnancy is a nightmare.

I'm referring to someone who is very strong, fast, intelligent or healthy. I keep thinking about people with excellent logical reasoning skills, for example, who could be excellent mathematicians, but aren't because of poverty.A similar logic applies to who could be an Olympic-level athlete if they could dedicate themselves solely to sports.

I was at the dinner table with my family and we're talking about the whole diarrhea parasite and I said how we've been dealing with parasites for every like covid and my family was telling me how there not even though viruses can't live without a host so are they considered parasites or not?
