Tomtit [17]
Emily's symptoms include frequent headaches, light sensitivity, nausea and vomiting. The risk factors are her smoking habit and the birth control pills that she is currently taking. A possible diagnosis could be an acute condition which is caused by a serious interaction between her smoking activity and her birth control pills. It has been proven that women who smoke while on contraceptive therapy have an increased risk of heart attack and stroke. This is because nicotine increases heart rate and blood pressure, while certain hormones present in some birth control pills (such as estrogen) increase the tension on blood vessels. For further diagnosis, the healthcare professional should check Emily's blood pressure and ask her family history on blood clots, heart problems, or stroke cases.

Drag the tiles to the correct boxes to complete the pairs.
kirill [66]

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.
