An aldosterone test measures the level of aldosterone (a hormone made by the adrenal glands), in the blood. Aldosterone helps regulate sodium and potassium levels in the body. This helps control blood pressure and the balance of fluids and electrolytes in the blood. The kidney hormone renin normally stimulates the adrenal glands to release aldosterone.
A seahorse* can have from 100-1500 babies. Averagly 100-200 for most species, but may be as low as 5 for the smaller species, or as high as 1,500. Seahorses can have up to 1500 fry at one time, depending on the species. They are tiny and difficult to raise in captivity.
Yes. Twins are 10 times more common in donkeys than in horses. Fewer than 1 in 1000 sets of twins in horses are estimated to be born healthy and alive, in donkeys, 1 in 100 sets will survive. Twin are far more common in the long eared equines and we hear of at least 10 sets being born and surviving every year.
