Which effect does a decrease in sunlight have on a pond ecosystem?
An increase in oxygen levels
An increase in the level of carbon dioxide in the blood should decrease the rate of breathing?
No: it would tend to call urgency into your body's systems to do all that can be done to decrease these toxic levels and increase the oxygen levels. This would considerably increase your breathing.
Why are higher levels of biodiversity good for ecosystem stability?
The higher the biodiversity, the higher the number of species, and the lower the rate of extinction. A decrease in biodiversity means a single species will become extinct and this will have a negative impact on other organisms for all organisms in an ecosystem are connected.
What is the variety of organisms considered at all levels from populations to ecosystems?
Biodiversity :P
Which is greater when blood calcium levels when parathyroid hormone is increased or decreased?
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
Will haptoglobin levels increase or decrease after HTR?
It will decrease.
What causes a decrease in phosphate nitrate and silicate levels in a body of water?
The recession does.
Would a growth factor increase or decrease cyclin levels?
decrease.
What can increase levels of phosphate in a stream?
Runoff from fertilizers is a strong contributor to high phosphate levels. At one time, phosphates were also used in detergents.
When blood CO2 levels increase does the pH increase or decrease?
It decreases.
Does grapefruit increase or decrease testosterone levels?
nope
Will increased hydronium ions increase pH levels?
no it will decrease the pH levels
What is negative feedback interaction between calcitonin and parathyroid hormone?
The parathyroid gland is the major regulator of blood Ca levels. When the Ca levels in the blood decrease, the parathyroid gland releases more parathyroid hormone. This in turn increases osteoclasts which results in more bone breakdown. this releases more Ca into the blood stream. When Ca levels in the blood increase the thyroid gland releases Calcitonin. this decreases the activity of the osteoclasts which in turn decrease the levels of Ca in the blood.
How surgical hypothyroidism would likely affect prolactin levels?
Thyroid hormones levels decrease, TRH levels increase, and PRL levels increase.
As thyroxine levels increase in the blood they exert negative feedback on the release of TSH by the pituitary gland. What effect will this have on the release of TSH?
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
