Thyroxine is a hormone that is  secreted by the thyroid gland to the blood stream. BMR is the basal metabolic rate that is affected by the levels of thyroxine hormone in the system. Hypophysectomy is the removal of the pituitary gland from an organism, in this case the rats. BMR rate of the rat seemed to increase with the injection of thyroxine however the BMR was still lower than the BMR of a normal rat with the thyroid gland  and the dose was too low.

In the northern hemisphere, when does the phytoplankton biomass peak in the polar region? why?
White raven [17]

Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.

As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.

In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.
