The production of fatty acids

Describe where the DNA is found in a human cell
Found in the nuclei of the chromosomes
3 of 17
What causes the cells during mitosis to be genetically identical?
DNA is cloned

Describe the function of muscle cells in the wall of the stomach
The muscles contract in order to churn and mix the food

What is the is the function of the mitochondria?
To transfer energy for use with respiration from glucose
8 of 17
Suggest why ribosomes CANNOT be seen through a light microscope
Ribosomes are too small and a light microscope doesn't have sufficient magnification
9 of 17
What is the function of a ribosome?
To make protein

Why was person 1 able to run much faster than person 2
More blood is sent to the muscles. Which supplies more oxygen and more glucose for a faster rate of respiration. This means less lactic acid is produced.

Suggest how the fossil of ARCHAEOPTERYX was formed
Animal would get covered by sediment leaving only the bones behind as the rest of the body would decay away
12 of 17
Suggest two reasons why there are gaps in the fossil records
Conditions not right for fossilisation. Geological activity could have destroyed some fossils

How could you eliminate heat from the light effecting a rate of photosynthesis
Submerge the sample in a water bath, use a low energy light bulb could be used so less heat is emitted.

Where does most of the reactions of aerobic respiration happen?
Mitochondria
15 of 17
Explain how oxygen passes through the blood
By diffusion which is the movement from an area of high concentration to that of low concentration by passing through a cell membrane
16 of 17
Describe how ribosomes help to make enzymes
Ribosome make protiens by using amino acids which the mitochondria provide the energy for the process
