Answer:
I would say all three describes the Sahara. Dry, thin soil sounds like sand, which is the soil in the Sahara Desert. This ecosystem definitely has a small amount of rain; that's what defines a desert. Along with that, the Sahara is also very diverse, inhabited by many organisms, from bugs, snakes, and other reptiles to rabbits, jackals, foxes, and even camels. Hope this helps!
Answer:
Two back-to-back phospholipid layers with the polar heads facing out on both sides
Explanation:
Phospholipids are made up of a head and two tails. The head can be described as a phosphate molecule that is water loving (hydrophilic) whereas fatty acids make up the two tails. The fatty acids repel water and hence are hydrophobic. The assembling of the phospholipids for the the formation of cell membrane depends on these hydrophilic and hydrophobic properties. The assembling of the phospholipids is in two layers. The phosphate head face outwards on both sides to attract water and the tails tend to hide from the water molecules by being composed in the layers of the head. this assembling is termed as the "self-assembly".
Genetic adaptability is very important to the survival and adaptability of any specie. This is because, in a diverse population, the possibility of finding individuals with the right genetic adaptability to the changing environment is higher, the population will have more possible adaptations.
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.
