at 30 the rate of photosythesis was at maxmuim if enzymes denatures then it should get to zero :|For Q1 part ii).....the one where they ask us to explain the shape of the graph after 30 degrees celsius.....i wrote that the plant will have to be a C3 plant and so the enzymes denature above 30 degrees thus decreasing rate of photosynthesis....
I wrote predicts the success of survival following implantation but doesn't predict the chances of successful implantation. And for then second disadvantage I wrote that the remaining embryos have to be discarded and how that presents as a ethical issue.
I wrote almost same.but dot you think its less fr total 15 marks?.for section B i chose 9, here are my points:
A) prokaryotic cell so smaller then eukaryotic cell, no nucleus, naked DNA, looped DNA, small circular strands of DNA called plasmids, cell wall made of peptidoglycans, may be protected by capsule, do not have double membraned organelles such as golgi body, and one more i think but i cant remember it
B) process called bioleeching, use thermophilic bacteria, bacteria must be able to cope with acidic conditions as H2SO4 produced, used on low quality ores where conventional is too expensive, bacteria are reused, family of bacteria called ferroxidans.
The question asked what percentage of the plasma was filtered right?
By your method,
12oo cm^3 blood -----> 700 cm^3 plasma
so 125 cm^3 blood -----> 72.9 cm^3 plasma.
The question wanted what PERCENTAGE of the plasma was filtered not the volume of plasma in 125 cm^3, so shouldn't it have been 72.9/700* 100 = 10.4% ?
yeah i had a doubt.....i wrote enyzymes denature as temperature increases above 30 degrees thus decreasing the rateat 30 the rate of photosythesis was at maxmuim if enzymes denatures then it should get to zero :|
no it doesntFor the key in the genetic cross, doesn't necessarily have to be 'W' right? :/
i dont remember the question but i guess t was asking ahy its at maximum at 30yeah i had a doubt.....i wrote enyzymes denature as temperature increases above 30 degrees thus decreasing the rate
Guys can I get the answer for the adaptations of the glomerular capillaries and podocytes for ultrafiltration??

What was that we have to label in that PCT or DCT it was i guess cant remember
Ph.mmicovilli
Oh. I left it blank.micovilli

For glomerular capillaries, i wrote about the high pressure created by difference in diameter of afferent and efferent, causing the filtrate to be passed through basement membrane
And for podocytes from about finger like projections, increase surface area, more diffusion
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
