Darwin explained that evolution occur due to natural selection.
Throughout the young larval stages a small gland behind the brain, called the corpus allatum, secretes juvenile hormone (also known as neotenin).
Answer:
coccidioidomycosis
Explanation:
Valley fever is also referred as coccidioidomycosis. It is an acute infection caused by a fungi called coccidioides. The fungi present in the soil in a particular region. The spores of the fungi spread into air through wind, construction work or farming. Through breathing fungi reached to the lungs causing valley fever. The symptoms of coccidioidomycosis includes fever, pain in chest and coughing. Mild valley fever get cured in due course of time by itself but in severe cases antifungal medicines are prescribed by the physicians.
Answer:
In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.
When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.
