hi miss beh! i'm a bit confused on how the continuous column of water makes it possible for water to move through the endodermis through the apoplast pathway, since water can only be transported through the symplast pathway in the endodermis as it is made of the casparian strip

i am quite confused about telomere being called as repetitive nucleotide sequence . Does it mean that all telomeres have same sequence of nucleotide???
@behlogy 17 сағат бұрын
No. It just means that each telomere has something that repeats. Like AT, so ATATATATAT. Or ATC, so ATCATCATCATC

Hi miss !! I received my AS level Results Yesterday i actually Got a C for Biology 😭... But Thank You so much for Doing this Amazing Job !!! Also im so worried about my results ... Will i be able to Pass well In A2 Level if i study harder ?? Or do i have to Retake my exam ? Hoping to Recieve a Positive response and I would Continue my A2 level by watching your videos only . Thank you :)
@behlogy 17 сағат бұрын
Dudeee thats kinda rough. A2 is significantly harder than AS, so most likely, at best, you will maintain your C. Or worst case, you may fail. If you need a certain grade for uni, I would retake AS. But if you only need a C, yeah I would just work really hard for A2!

hi ms beh. at 30:35 i think u misinterpreted the slide? i think the slide meant that generally there should be no or few proteins in urine as the proteins dont pass through the basement membrane of bowmans capsule and so retained in blood and the ones that do pass through the basement membrane at the bowmans capsule would be reabsorbed back into the blood at pct. but what u said was that long term presence of protein in urine MEANS most proteins molecules dont pass through the basement membrane (but it actually should mean that proteins are now passing through the basement membrane and not being retained in the blood as it should have been). sorry if im missing out on anything tho and really appreciate the free videos

36:01 I don't really get how risk of spreading antibiotic disease to other bacteria is a problem.. I also don't get how antibiotics being less effective in disease-causing bacteria is relevant in this case because why would someone use them as vectors instead of normal bacteria? for 41:01, what you mean by "chemically identical to human insulin" is the human insulin produced from the recombinant DNA genes is chemically identical to the human insulin in our body right? And 43:13 how does bacteria's organelles not being membrane-bound make its proteins not able to be genetically modified?
@behlogy 8 күн бұрын
Antibiotic resistance is problem bcs bacteria can pass the plasmid containing the resistance gene to other bacteria. Labs often use E. Coli which does cause disease if not properly killed and managed. We use bcs it replicates fast. You only fall sick if you eat it. Buttt what if you accidentally do? Cant kill it now Human insulin has unique glycoprotein structure. So it's not just the polypeptide thats needed. We need to add on the sugar branches in a specific manner to make it chemically identical to human insulin and be recognised as "self". Insulin without the sugar branches still work tho, just that it may be less effective. Bcs modification of protein is needed and it occurs usually in golgi or ER... Bacteria dont have these organelles, so we cant make it in bacteria. We use a diff method you dont really learn in a level

while describing about the reciprocal thing in textbook there is written you do not need to understand how to do this. So can i just remember only the fact that the graph is obtained only when few experiments are done and at some point of all experiments the initial rate of reaction happens at constant rate for all experiments?

Oh cool, i havent noticed that line in the textbook. I get why you made that assumption and i can say that's true for graphs that is rate against [S] and [P]. But not for temperature and pH.

Same base pairs, as in the same pair. So A binds with T. C binds with G. Sorry english is weird/unclear sometimes. Please avoid that phrase if it causes confusion. Did i say that somewhere this video?

Great video! Just one question: If the hydrogen that combines with NADP to reduce it can only come from the photolysis of water, what happens to all the other H+ ions that get pumped across the membrane? Where do they come from and where do they go?
@behlogy 19 күн бұрын
Most of them kinda stay there help maintain that proton gradient, so that protons can keep flowing through ATP syntase so that it rotates and generates ATP. haha. Then they are pumped back into the intermembrane space again. Some of them get used in other reactions/transported else where too. E.g. Plant cells also have mitochondria! So they help there as well
