Cardiovascular features unique to the Fetus:
Fetal circulation is characterized by low systemic vascular resistance (SVR) with high systemic blood flow and high pulmonary vascular resistance with low pulmonary blood flow.
<h3>What is fetal circulation?</h3>
The embryonic circulatory system directs blood that needs oxygen through three shunts, or microscopic tunnels. These shunts are intended to avoid forming organs like the liver and lungs while the fetus is still in the womb.
The foramen ovale, which carries blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, which takes blood from the pulmonary artery to the aorta, are the two shunts that bypass the lungs.
Through the placenta, the mother's blood supplies the fetus with nutrition and oxygen. The enhanced blood divides into three branches as it travels via the umbilical cord to the liver.

The correct answer is protein.
The Recommended Dietary Allowance (RDA) is set by the Food and Nutrition Board of the Institute of Medicine. It represents the average daily level of nutrient intake which is sufficient to meet the needs of nearly all healthy people.
According to the RDA, the daily intake of protein for healthy adults is 0.8 grams per kilogram of body weight.
The right answer is both of them.
Take the example of fatty acids, it is an aliphatic chain carboxylic acid composed of 4 to 36 carbon molecules. The more carbons (and therefore the CC and CH bonds), the more the fatty acid will be rich in energy since it will give more ATP during its catabolism, and it will also be less and less soluble in water because the carbon chain is hydrphobic.
