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.

A secondary source is anything written after the fact
Answer:
If the question is referring to Mendel's postulates, all options are correct
Explanation:
Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.
During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.
Cycloalkanes
are saturated hydrocarbons with monocyclic structure.
<span>This
means that cycloalkanes contain hydrogen and carbon atoms arranged in a
structure containing a single ring (sometimes with side chains), with all of
the carbon-carbon bonds single. The examples of cycloalkanes are cyclopropane,
cyclobutane, cyclopentane, cyclohexane…</span>
