Letter C indicates what part of the nephron?
Loop of Henle
Proximal Convoluted Tubule
Bowman's Capsule
Glomerulus
Collecting Duct
The Correct Answer is C
A. Loop of Henle: The Loop of Henle is the U-shaped segment of the nephron that extends into the medulla and concentrates urine.
B. Proximal Convoluted Tubule: The PCT is the first convoluted segment after Bowman's capsule and is responsible for bulk reabsorption of solutes and water.
C. Bowman's Capsule: Bowman's capsule is the double-walled cup that surrounds the glomerular capillary tuft and collects filtrate.
D. Glomerulus: The glomerulus is the capillary tuft inside Bowman's capsule that performs plasma filtration.
E. Collecting Duct: The collecting duct collects filtrate from multiple nephrons and participates in final water/solute adjustments.

Correct Answer is ["C","D"]
Explanation
A. Urea: Urea is a normal nitrogenous waste product excreted in urine; its presence alone is not indicative of diabetes (it reflects protein metabolism/kidney function).
B. Creatinine: Creatinine is a normal urinary waste product used to assess kidney function; its presence alone is not diagnostic of diabetes.
C. Glucose: Glucosuria (significant glucose in urine) suggests hyperglycemia and impaired glucose handling (common in diabetes) -indicative of a diabetic problem if present in large amounts.
D. Ketones: Ketonuria (significant ketones in urine) indicates fat breakdown/ketosis and is a sign of uncontrolled diabetes (e.g., diabetic ketoacidosis) -indicative of diabetic metabolic disturbance.
Correct Answer is A
Explanation
A. Responsible for uterine contractions: The myometrium is the thick middle layer of uterine smooth muscle and is the contractile layer responsible for rhythmic uterine contractions (e.g., labor, Braxton–Hicks) .
B. Primary support for the uterus: Structural support of the uterus is provided mainly by pelvic ligaments and pelvic floor muscles; this is not the primary role of the myometrium.
C. Thickens in response to estrogen: The endometrium (the mucosal lining) thickens cyclically in response to estrogen; the myometrium undergoes hypertrophy in pregnancy but is not the layer described by cyclic thickening of the uterine lining.
D. Covers the exterior portion of the uterus: The outer covering of the uterus is the perimetrium (serosa), not the myometrium.
