The urinary system is the main excretory system of the body after the gastrointestinal tract (large intestine) and lungs, In these questions it is necessary to prioritize the urinary tract.
The right answer is D. Bladder
The bladder belongs to the urinary excretory system.
The bladder receives the urine produced by the kidneys via the ureter and has the function of storing it before its elimination during urination through the urethra. The muscles surrounding the bladder help to prevent urine reflux to the ureter.
The right answer is C. Kidneys
The main purpose of the renal excretory system is to eliminate nitrogenous wastes while maintaining homeostasis, all through the formation of urine.
The kidney has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon (triangle based on the renal hilum) origin of the ureter. We speak of pyelo-ureteral junction. Each kidney contains about 1 million nephron.
Acid rain, if I understand the question correctly.
Answer:
-20 kcal/mol (It stays the same)
Explanation:
Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.
Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.
Free energy of reaction
= free energy of product - free energy of substrate
The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.
The attached image shows the effect of changes in enzyme concentration on the free energy.
