Answer:
There would be no seasons anywhere on Earth
Explanation:
If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.
False, pernicious anemia may take up to 5 years to show symptoms. However, the oxygen starts to get depleted within the first 6 months in thalassemia major.
Pernicious anemia:
In this condition, the body is unable to absorb vitamin B12 which leads to lowered amount of red blood cells which are responsible for carrying oxygen throughout the body. It is an autoimmune disease in which antibodies attack their own cells in the lining of the stomach which affects the absorption of vitamin B12. The symptoms of pernicious anemia are dizziness, fatigue, diarrhea, constipation, breathlessness, and loss of appetite. The depletion of oxygen is seen in thalassemia major within 6 months.
