Question 3 you could say that…
The closer you are to the equator (30N-30S) the more solar radiation present. This leads to, less clouds appearing in them areas and the climate bring quite hot.
Answer: True
Explanation: The Achilles tendon is the largest and the strongest tendon in the body. When the calf muscles flex, the Achilles tendon pulls on the heel. This allows us to stand on our toes when walking, running, or jumping.
Answer:
Patent ductus arteriosus (PDA) is an extra blood vessel found in babies before birth and just after birth.
Explanation:
The ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart.
The lungs are not used while a fetus is in the womb because the baby gets oxygen directly from the mother's placenta. The ductus arteriosus carries blood away from the lungs and sends it directly to the body. When a newborn breathes and begins to use the lungs, the ductus is no longer needed and usually closes by itself during the first 2 days after birth.
If the ductus doesn't close, the result is a patent (meaning "open") ductus arteriosus. The PDA lets oxygen-rich blood (blood high in oxygen) from the aorta mix with oxygen-poor blood (blood low in oxygen) in the pulmonary artery. As a result, too much blood flows into the lungs, which puts a strain on the heart and increases blood pressure in the pulmonary arteries.
Answer:
- Dry climates do not have sufficient <u>moisture</u> during most of the year.
- Deserts are located in the <u>arid</u> climate.
- The <u>temperate</u> climate is in a grassland, or steppe, region.
Explanation:
Desert climate develop when the rate of evaporation is extremely higher than the rate of precipitation. This means that the moisture content would be very low in most of the times of the year. Hence, in the long run, the climate will become semi-arid to arid.
On the other hand, temperate climates reflects the conditons of moderate rainfall that spreads across the year or most time of the year. Usually, temperate climate has sporadic drought, mild to warm summers and cool to cold winters. These conditions are enough supporting to produce grasslands, or steppe.
