can anyone help i struggle with biology :)
In fish and chip shops, potatoes are cut into chips several hours before they are cooked.
The mass of water in the chips must be kept constant.
To ensure this, the chips are kept in sodium chloride solution.
The drawing shows some apparatus and materials (Potato slices, tweezers, knife, test tubes, and some weighing scales)
Describe how you would use the apparatus and materials to find the concentration of sodium chloride in which to keep the chips so that the mass of water in the chips remains constant.
you must include: measurements, and how youd make it a fair test. 6 marks.
I dont neccessarily need a full answer, just some help!! thank you!!

Heidi is doing a sit-up for P.E. class. Which of the following muscles is she using?
Answers
Answer:
d. All of the above
Explanation: is correct
Our muscle cells sometimes turn to lactic acid fermentation rather than respiration in order to produce energy because they
A.run low on glucose and need something to replace it.
B.produce too much oxygen for our bodies to handle.
C.use up all the pyruvates and must compensate with fermentation.
D.do not receive enough oxygen during strenuous exercise.
Answers
Explanation:
D) do not receive enough oxygen during strenuous exercise is right answer.
Muscle cells turn to lactic acid fermentation rather than respiration when they do not receive enough oxygen during strenuous exercise. Thus, the correct option is D.
What is Lactic acid fermentation?Lactic acid fermentation is a metabolic process in which glucose and other sugars are converted into the cellular energy (ATP) and lactic acid. It is a form of anaerobic fermentation reaction which occurs in some of the bacterial cells and animal cells, like muscle cells.
When the muscles are contracting very quickly during strenuous exercise, the oxygen cannot travel fast enough to the muscle cells to keep up with the need of ATP in the muscles. At this point, the muscle fibers switches to a breakdown process which does not require much oxygen (anaerobic respiration).
The muscle cells produce ATP with the lactic acid to give you energy during these difficult physical activities. This condition results when there is not enough oxygen in the body to produce ATP, so the lactic acid fermentation provides acts as a substitute to get ATP without oxygen.
Therefore, the correct option is D.

This process your body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
The relationship between stem cells and gene expression is the process by which the body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
What is stem cell?Stem cell has been defined as the cell and the raw material of the body and these are the cells which has been specialized the function has been generated. In the right condition of the body or the laboratory, the stem cells has been divided to form the cells known as the daughter cell.
Daughter cell is known as daughter cell because they have to divide again the this quality of division is just the character of daughter cell. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
