GCSE OCR Biology B4 B5 B6 12th June 2014

In the first question I think it wanted to talk about active transport but on the second part there was emphasis on the roots being above the ground so I think it wanted you to talk more about creating energy for growth etc by absorbing O2 but you will still probably get marks ☺️. What did everyone put for the surface area of the rats intestines increasing !?

The majority of my friends and me said it was fungi with 7%. Although, I did initially think that it was prokaryotes.

Didn't really like that exam though...

What was the second question? I only remember one about roots respiring etc?

The first question was about nutrient content being low due to lack of active transport and the second was about roots but above the ground as shown in the picture

I wrote about bacteria for the first part, as it was about the nutrient content being low, not why the plant takes it up in low concentrations

It was prokaryotes. It asked for the kingdom the was the least found, or something - not estimated for the future. 0.88% was correct

What do you think about what I wrote:

The fan increases the movement of air particles, which means that water molecules can evaporate into water vapour. In A, there will be no mass change, because of the oil, which will inhibit water molecules from evaporating into the atmosphere. However, with B, mass will decrease, as the plant will move water up through the xylem to the leaves, where they will be exposed the high movement of the air particles, and hence evaporate into water vapour. Hence, A will not lose any mass, whereas B will continuously lose mass due to the continuous transpiration pull that brings water to the surface of the leaf, where it can evaporate.

The hip joint is an example of a ball and socket joint. As a result, there is a large range of movement available in all directions. Norman's joint, however, is very large, which means that there is less synovial fluid. Synovial fluid absorbs shock and acts a lubricant, preventing friction. Since he has less synovial fluid, there will be more friction opposing his motion, thereby leading to him having a smaller range of movement.

For your second answer, mine was very similar. But my friends talked about osteoporosis... The brittle bone

yes but the nutrient content is low due to less active tansport , I can't really remember the question exactly some of them were worded weirdly

I got fungi with 7% question was badly worded

what did u guys get for why the discovered amount of species was higher than the estimated. I said because living things are on a continuous stage of evolution and somet else cant remember what else i put.

I put something similiar like creatures are constantly evolving so one species may have been counted more than once because they have changed due to evolution
