Edexcel GCSE Biology Additional (B2) - 5th June

please can you send them to me!!!

The first answer is from a foundation paper, but when I first saw it I was like wtf.
The second is a 6 marker I made up, because I just needed a way to remember the digestive system incase it did come up for a 6 marker.

Again, I have written model answers to all of the 6 marker higher past papers, if anyone wants them drop me a message and I'll email you.

“Explain how thestructure of the heart is related to their function.”
The heart is made up of two sides, the right side and theleft side. The splitting up of these two sides prevents the blood from mixingtogether. Additionally, the right side (right atrium, and right ventricle)deals with deoxygenated blood and transports the blood to the lungs at a lowpressure. In comparison, the left side (left atrium and left ventricle) dealwith oxygenated blood. The left ventricle has a much thicker muscle wall,because it has to pump blood all around the body at a high pressure, not justto the lungs like the right side. The muscular walls of both ventriclescontract when full and push the blood to their designated area. The pulmonaryartery carries blood away from the heart, and the pulmonary vein carries bloodtowards the heart. The heart also contains valves. Valves are flaps of tissuewhich prevent back flow from the ventricle to the atrium. The aorta carries theoxygenated blood around the body. The mouth contain teeth which grinds the food down intosmaller pieces. The mouth also contains saliva which helps to lubricate thefood and form it into a bolus. This is so the food can travel down theoesophagus more easily. The oesophagus pushes the food down into the stomach byperistalsis, this is where the muscles contract in waves which pushes the bolusdown. The food is then transported into the stomach, which churns up the food.The stomach contains hydrochloric acid, which helps to break down the food intoeven smaller pieces. The stomach also contains protease. These enzymes convertthe proteins in the food into amino acids. All the digested food is dissolvedinto the plasma. However, undigested food is sent to the small intestine, whichbreaks down the insoluble molecules into more soluble substances. The liverexcretes bile into the small intestine, which neutralises the ph. of the foodfrom the stomach and emulsifies fat. The small intestine also contain lipase (whichconvert fats into fatty acids and glycerol) and amylase (which convert starchinto sugars.) The small intestine is also lined with villi which allows for theabsorption of food to happen more easily. Undigested food is sent to the largeintestine. The water from the food and diffuses back into the blood and theundigested food passes out of the anus as faeces.k�u>~G��

I'm really hoping for questions to come up about meiosis/mitosis, the heart/digestive system, enzymes, diffusion/osmosis/active transport, cloning benefits and risks or dangers, structures of cells, and almost anything to do with tables or graphs😂
Hoping for an A* but considering my recent mistakes, around 40 marks seems much more likely, what gradesare you guys aiming for?

Yeah best tjing to do, what did you get in your controlled assessment?
