The wind and pollen dropping from trees
Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.

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.

Answer:
Sartorius is inserted in the tibia.
Explanation:
Sartorius muscle is orginated from the iliac spine of the pelvioc bone. This muscle is the longest muscle of the human body. This muscle runs down on the thigh's anterior compartment.
The sartorius muscle is inserted in the anteromedial surface of the proximal tibia in the pesanserius. The insertion can be shown on the upper medial of the tibia. Femoral nerve innervates the sartorius muscle.
