Compared to the nervous system, the endocrine system:
Is not essential to life.
Takes only seconds.
May have a longer-lasting effect.
Does not use receptors.
The Correct Answer is C
The endocrine system may have a longer-lasting effect than the nervous system because the hormones it produces can circulate in the bloodstream for a long time and affect many organs and tissues.
The nervous system, on the other hand, uses nerve impulses and neurotransmitters for communication, which are faster but more short-lived.
Choice A is wrong because the endocrine system is essential to life.
It regulates many vital functions such as metabolism, growth, reproduction, mood, sleep, and blood pressure.
Choice B is wrong because the endocrine system takes longer than the nervous system to deliver its messages.
The hormones have to travel through the bloodstream to reach their target cells, while the nerve impulses can travel along the nerve fibers at high speeds.
Choice D is wrong because the endocrine system does use receptors.
The hormones bind to specific receptors on the target cells to trigger a response.

Correct Answer is B
Explanation
Kidneys are not part of the lymphatic system.
The lymphatic system is a network of vessels and organs that drain excess fluid from the tissues, transport fats and immune cells, and protect the body from infections.
Kidneys are part of the urinary system, which filters blood, regulates fluid and electrolyte balance, and produces urine.
Choice A is wrong because kidneys do not have a direct connection to the lymphatic system.
Although kidneys have lymphatic vessels in their cortex, they do not originate from the lymphatic system.
Kidneys receive blood from the renal arteries and return it to the renal veins.
The lymphatic vessels in the kidney cortex drain interstitial fluid and immune cells from the kidney tissue to the regional lymph nodes.
Some additional sentences are:
Choice B is right because kidneys are part of the urinary system, not the lymphatic system.
The urinary system and the lymphatic system have different functions and structures in the body.
Normal ranges for kidney function tests include blood urea nitrogen (BUN) of 7 to 20 mg/dL, serum creatinine of 0.6 to 1.2 mg/dL, and glomerular filtration rate (GFR) of more than 90 mL/min/1.73 m.
Normal ranges for lymphatic system tests include white blood cell (WBC) count of 4,000 to 11,000 cells per microliter, lymphocyte count of 1,000 to 4,800 cells per microliter, and immunoglobulin levels of IgG (700 to 1,600 mg/dL), IgA (70 to 400 mg/dL), IgM (40 to 230
mg/dL), IgE (0 to 100 IU/mL), and IgD (0.5 to 5 mg/dL).
Correct Answer is C
Explanation
This list best illustrates the idea of increasing levels of complexity because it follows the biological hierarchy of organization from the simplest to the most complex units of matter.
Each level is composed of units from the previous level and has emergent properties that are not present in the lower levels.
Choice A is wrong because it reverses the order of organelles and cells. Organelles are subcellular structures that perform specific functions within cells.
Cells are the basic units of life that can carry out all the processes of living organisms.
Choice B is wrong because it reverses the order of tissues and organelles. Tissues are groups of similar cells that work together to perform a common function. Organelles are more basic than tissues and are found within cells.
Choice D is wrong because it reverses the order of organs and organelles.
Organs are structures composed of two or more types of tissues that perform a specific function or function.
Organelles are more basic than organs and are found within cells.
