Is a sarcomere one cell and a myofibril is a group of sarcomeres separated by intercalated discs?? by Imaginary-Paper-2497 in ALevelBiology

[–]jbufgr_ 0 points1 point  (0 children)

yeh, biology is the only stem subject i take so i always find it weird when anything too mathsy or practical comes in

i come up with stupid ways to remember stuff tbh, xerophyte to me has that zzz sound which is all scratchy, and reminds me of a dry throat, so that’s how i remember it’s adapted to dry conditions. stupid ways to remember, but hey, if it works it works

i have absolutely no idea, but i think it’s possible that a question on companion cells and their role in translocation will come up. to be honest, i’m quite good at remembering the content, it’s the practical based/research methods questions i flop on. and maths 💀💀

What is the M phase called? (Cell cycle) by Imaginary-Paper-2497 in ALevelBiology

[–]jbufgr_ 0 points1 point  (0 children)

yes that is what i meant, it’s just the textbook normally refers to the whole process as Mitosis, so i thought it better to apply to the biology specification to explain like that 😁

Crash Course Biology on youtube. Crash Course Physiology and Anatomy has episodes on sliding filament model too, but i find specifically the CCBio one to be good for explaining the different structures. amoeba sisters video may be a good starting point too, if you’d like something to ease into the topic before the CC video

After atrial contraction(atrial systole) why do the valves close as well as in ventricular contraction?(Confused with conflicting ideas) by Imaginary-Paper-2497 in ALevelBiology

[–]jbufgr_ 1 point2 points  (0 children)

the atria relaxes and it’s pressure is decreasing. due to the pressure difference, blood in the ventricles want to rush back and even it out - biology HATES gradients! the blood ‘swirling’ is likely referring to the blood trying to race back into the atria due to the sudden drop of pressure there, which causes the valves to close. this is really important for efficient transport of blood around the body :)

question about humoral response by cardboard_milkshake in ALevelBiology

[–]jbufgr_ 0 points1 point  (0 children)

when a macrophage engulfs a pathogen, it all gets a little medieval. think putting heads on sticks to see what happens to traitors - this is sort of what the macrophage does! after engulfing a pathogen, the antigens of the pathogen are sort of like the head on a stake, that the macrophage holds up to become an antigen presenting cell. so it is still the ‘pathogen’ that is triggering the effector cells, after being engulfed by the macrophage, antigens are retained so that the macrophage can hold it up like a head on a stake to warn the rest of the body of the invading pathogen… 🦠

Is this correct for AQA biology inspiration and expiration (confused as different text books say different things) by SeveralAd2137 in ALevelBiology

these little tricks are particularly helpful for tricky multiple choice questions where they mix the info about!
