Answer:
A. Most plats in the ditch will be plants with long roots.
Explanation:
Because the plants with shallower roots systems are easily uprooted by the rain, and there is lots of rain that year, natural selection will choose the long rooted plats. They are the "strongest" in evolution's eyes because they are less likely to die by being uprooted.
Answer:
The correct answer will be option-E.
Explanation:
The papillary muscles are the small muscles which arise in ventricles of the heart. These muscles are attached to the atrio-ventricular valves of the heart through chordae tendineae made up of fibrous tissues.
These muscle help prevent the backflow of the blood to the atria during ventricular systole or contraction. These muscle gets activated before the contraction which pulls the chordae tendinae attached to the cusps of the valve, thus closes the leaflets.
Thus, option- E is the correct answer.
Answer:
D. the kingdom name is listed first
Explanation:
The genus name is listed first, not the kingdom name. The kingdom name isn't even is the scientific name.
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.
