http://t.co/2Su17tfRsG Use this to revise the chemistry. You need to know all topics. Fuels is a huge topic! #C1 #Thursday #C1exam #GCSE2015

[Haygrove Science @HaygroveScience]

depending on the level of water in the blood, more/less water is absorbed (osmoregulation) at the collecting duct #b3

[Haygrove Science @HaygroveScience]

@HaygroveScience Selective reabsorption of eg glucose, happens at the convoluted tubule using active transport #b3

[Haygrove Science @HaygroveScience]

In which direction does centripetal force act? #P3

[Haygrove Science @HaygroveScience]

@HaygroveScience The filtrate runs into the Bowman's capsule. QUESTION: What remains in the blood capillary and why? ANSWER PLEASE #B3

[Haygrove Science @HaygroveScience]

1) Ultrafiltration. Blood flowing under high pressure from renal artery. GLOMERULUS = capillary network.

A convex lens corrects long sightedness.#P3

[Haygrove Science @HaygroveScience]

A concave lens helps short sightedness. #P3

[Haygrove Science @HaygroveScience]

The closest a normal human adult eye focuses is 25 cm called the near point. The furthest is said to be infinity called the far point. #P3

[Haygrove Science @HaygroveScience]

Do you remember the parts of the eye? #P3 What is the function of each part?

[Haygrove Science @HaygroveScience]

Have a lesson on Snell's Law for exam revision #P3. https://t.co/jNWreXV46H

Frequency of a beating heart is calculated:

Frequency (hertz, Hz) = 1 / time period (second, s)

How can you calcultate the time period?

More from drphysicsa - this one is on lenses and ray diagrams. #P3 https://t.co/DKDRP0oN05

[Haygrove Science @HaygroveScience]

Heart beat, pulse, ECG, pulse oximetry - remind yourself how these work. #P3 https://t.co/hsm2pOUbZp

[Haygrove Science @HaygroveScience]

Mitochondrial DNA might come up! #b3

[Haygrove Science @HaygroveScience]

Don't forget to have a look at this. Can't recommend the videos on this playlist enough... https://t.co/tq7Kv8Dx3e #b3

[Haygrove Science @HaygroveScience]

What are the 3 main process that happen within the nephron? TWEET! #b3

[OAJW Science @OAJWSci]

So additional you are finished! Triple, 3 to go! Wasn't at the end of the exam yesterday, hope it went well! Hope the paper was good!

Notes from P2 session. No uses of radiation here. Make sure you check how to dispose of radioactive waste...

[OAJW Science @OAJWSci]

Not a bad prediction crossover (I didn't see this first). Resistance and components (LDR, Thermistor / Diodes) https://t.co/VF7oAnocc5

[Haygrove Science @HaygroveScience]

Remember these are just predictions, but here they are for #p2
