Answer:
The answer to number 7 is A. Hibernation
The answer would be: an increase in the production of new plasma HCO3-
In metabolic acidosis, the pH of the blood is too acid which means there is too much H+ ion in the blood. The kidney can compensate it by making more OH- and dump more H+ to the urine.
The H+ is not filtered, it was secreted by the cells. More H+ will decrease the pH of the urine, makes it more acid. Acid secretion allows more HCO3- production.
Bicarbonate or HCO3- is base ion and increasing its production will lower the blood pH.
Answer: It is called Accommodation.
Explanation:
Retina is the innermost and sensitive tissues around the eye, it is located near the optic nerve. The function of retina is receive light that lens has focused and convert those light to neural message and send the signals to the brain for interpretation.
Accomodation is the adjustment of objects at varrying distance. When the crystalline lens change shapes, it changes the focal distance of the eye so that object at different distances can be focused on and thus allowing the formation of clear and real image on the retina, this adjustment of lens is called accommodation. The crystalline lens of the eye is located at the iris and it is made up of fibres from the epithelial cells.
