Explanation:

First Question (Urine transport to bladder)

To determine how urine is carried to the urinary bladder, we analyze each option:

• "All of the above" is incorrect as other options are not all correct.
• "Blood vessels" transport blood, not urine.
• "The ureters" are the tubes that carry urine from the kidneys to the urinary bladder. This is correct.
• "The urethra" carries urine from the bladder out of the body, not to the bladder.
• "Lymphatics" are part of the lymphatic system, not involved in urine transport.

To identify the eye receptors for vision, we analyze each option:

• "Retina" is the layer containing receptors but is not the receptor itself.
• "Optic nerve" transmits visual information, not a receptor.
• "Photoreceptors" (rods and cones) in the retina detect light and provide vision. This is correct.
• "Cornea" is the outer lens - like structure, not a receptor.

Answer:

C. the ureters
