Thyroxine is a hormone produced by the thyroid gland. A decrease in body temperature causes an increase in thyroxine production. Choose two sentences to explain how the production of thyroxine causes an increase in body temperature.

ADH is a hormone made by the pituitary gland. ADH controls how much water is reabsorbed from the kidney tubules.
The concentration of ADH in a man’s blood was 3.75 nanograms/dm3.
The concentration of ADH in his blood decreased to 1.25 nanograms/dm3.
Explain how the decrease in the concentration of ADH would cause the changes to the urine shown in the table above.
Tubules less permeable to water so less is reabsorbed. More water in urine causing increased rate of production of urine causing lower concentration of dissolved substances in urine.
Tubules more permeable to water so more is reabsorbed. Less water in urine causing decreased rate of production of urine causing higher concentration of dissolved substances in urine.
Tubules less permeable to water so more is reabsorbed. Less water in urine causing increased rate of production of urine causing lower concentration of dissolved substances in urine.
Before treatment with FSH, the woman had underdeveloped breasts.
Explain why the lack of FSH in the woman’s blood caused underdeveloped breasts.

lack of FSH causes lack of progesterone and breast development is dependent on progesterone
lack of FSH causes increase of oestrogen and breast development is dependent on oestrogen
lack of FSH causes lack of testosterone and breast development is dependent on testosterone
