The component of urinalysis that reflects the amount of waste products and solids in urine is called Specific Gravity
A urine test examines the various elements in urine.
The kidneys filter the blood to remove waste products, minerals, water, and other chemicals that are then excreted in the urine. There are countless distinct bodily wastes in urine.
Urine can be used in more than 100 different tests. The tests for color, clarity, odor and specific gravity are frequently performed as part of a routine urinalysis.
The amount of chemicals in the urine is measured using specific gravity. Additionally, it demonstrates how effectively the kidneys regulate the amount of water in urine.
The more solid stuff there is in the urine, the greater its specific gravity. When you consume a lot of liquids, your kidneys produce urine with low specific gravity and high water content. Your kidneys produce urine with high specific gravity and little water when you don't drink any fluids.

Answer: cell wall, chloroplasts, plastids, and a central vacuole
Explanation:
Most plants have roots, but there are some
exceptions. The exceptions are bryophytes
and the groups of green algae that are
classified as plants. Bryophytes have rootlike
structures called rhizoids for absorbing
water, but because rhizoids lack vascular
tissue they are not considered roots.
