Why is it better to store seeds from several individual plants of one species rather than seeds from one individual plant?
Where are mitochondria located in an egg cell? What does this look like?
In an investigation where a student studied the mass needed to break dry plant fibres, which 3 factors would need to be kept constant?
How would the results obtained from an investigation where a student studied the mass needed to break dry plant fibres be processed to produce a mean?
What might the safety role of a container with a soft fabric be in an investigation where a student studied the mass needed to break dry plant fibres?
In an investigation into the mass required to break four samples of an oil-based plastic fibre, the mass required to break the 1st sample was 13,330 g, for the 2nd it was 2,300 g, for the 3rd it was 13,600 g & for the 4th it was 13,600 g. Why was the mean for the plastic fibre calculated using only of the 3 results?
What contains a haploid number of chromosomes in a sperm cell? What does this look like?

Can pluripotent stem cells give rise to totipotent stem or differentiated cells?

What accepts the ADH when osmoreceptors detect an increasing plasma concentration of inorganic ions?
What is not the only hormone that affects the kidney tubules & controls the amount of urine formed in response to changes in the body?
To what are membranes not permeable unless there are protein channels or carrier proteins present?
What results in a reduction in blood volume, causing blood pressure to fall?
What also drop when ADH levels fall? What are taken out of the tubule membranes & repackaged in vesicles, making the tubule impermeable to water again?
What detect an increasing plasma concentration of inorganic ions? Where do they send nerve impulses to, which consequently releases stored ADH into the blood?
Does the concentration of inorganic ions in the blood rise or fall if water is in short supply or you sweat a lot or eat a very salty meal? Does this mean that its water potential become more negative or positive?
What are less permeable to water if less ADH is released? How much water is, therefore, reabsorbed, causing large amounts of dilute urine to be produced?
