Which of the following is the healthiest ratio of triglycerides __________.
High HDL: low LDL
High LDL: low chylomicron
High SFA: low HDL
High LDL: low HDL
The Correct Answer is A
A. High HDL: low LDL- High-density lipoprotein (HDL) is known as "good cholesterol" because it helps remove cholesterol from the arteries. Low-density lipoprotein (LDL) is known as "bad cholesterol" because it can lead to plaque buildup in arteries. A high HDL to low LDL ratio is considered healthy as it is associated with a lower risk of cardiovascular disease.
B. High LDL: low chylomicron- High levels of LDL are unhealthy as they increase the risk of plaque formation in arteries, which can lead to cardiovascular diseases. Chylomicrons are lipoproteins that transport triglycerides and cholesterol from the intestines to other parts of the body.
C. High SFA: low HDL- Saturated fatty acids (SFA) can raise LDL levels and lower HDL levels, leading to an unhealthy lipid profile and increased risk of heart disease.
D. High LDL: low HDL- High LDL and low HDL is an unhealthy combination because it increases the risk of cardiovascular disease due to higher potential for plaque buildup in the arteries.

Correct Answer is D
Explanation
A. Ca2+: prevents the entrance of any more sperm- While calcium ions play a role in the slow block to polyspermy, the fast block involves sodium ions.
B. Na+: prevents the entrance of more Na- The fast block to polyspermy involves sodium ions (Na+), but the depolarization of the egg membrane prevents the entrance of more sperm, not just more Na+.
C. Na+: prevents the entrance of Ca2+. The fast block prevents additional sperm from entering, not calcium ions.
D. Na+: prevents the entrance of any more sperm: The fast block to polyspermy involves the opening of sodium ion channels, leading to depolarization of the egg membrane. This depolarization prevents other sperm from binding to and penetrating the egg.
Correct Answer is B
Explanation
A. Glomerular capillaries are involved in the filtration of blood to form the glomerular filtrate, not in the reabsorption of glucose and amino acids.
B. Proximal convoluted tubule is where the majority of glucose and amino acids are reabsorbed from the glomerular filtrate back into the bloodstream.
C. Renal corpuscle consists of the glomerulus and Bowman's capsule and is involved in the filtration process, not in reabsorption.
D. Distal convoluted tubule is involved in the fine-tuning of electrolyte and acid-base balance, not in the primary reabsorption of glucose and amino acids.
