Answer:
The keynote address
Explanation:
In 2004, the Ex-US president, Barak Obama delivered the keynote speech at the National Convention. The speech sets the main theme of the convention straight and this keynote address aided his chance of becoming the US president in 2004.
Barak Obama was one of the several people considered to deliver keynote addresses at the National Convention. Obama's keynote address included his autobiography, his vision for the United State of America and how racism can be dealt with among the citizens and residents of the United States and his reasons for supporting John Kerry for the presidency.
He talked about how his grandparents who were from Kenyan survived particularly his paternal grandfather who worked as a domestic servant for the British colonial masters and how his father migrated to the United State through a scholarship to study in the United States. His maternal grandfather fought under Patton in World War II. He addressed the issue of how the course of living in the United States would be improved especially in the course of job, education, healthcare. Many writers and academics have studied the speech and evaluate it since its delivery. At the end of his address, he talked about the audacity of hope of citizens and residents including the immigrants living under average.
Answer:
cross-sectional study
Explanation:
Cross-sectional study -
It refers to the process of observational studies , where some samples for observation is selected from a full lot of objects , is referred to as cross - sectional study .
It is also called as prevalence study , transverse study or cross-sectional analysis .
The samples are selected on the basis of age , gender , knowledge , height etc. , and then experimentation are done .
Hence , from the given scenario of the question ,
The correct answer is cross - sectional study .
Crystalline silicon (c-Si) dominates wafer-based solar cells. On the other hand, amorphous silicon (a-Si) plays a vital role in thin-film solar cells. Yet, both types of solar cells employ silicon.
Crystalline silicon is the dominant semiconducting fabric used in photovoltaic technology for the manufacturing of solar cells. Those cells are assembled into solar panels as part of a photovoltaic device to generate solar electricity from sunlight. Crystalline silicon (c-Si) cells are received from skinny slices of silicon (wafers) one hundred sixty–240 μm thick, reduce from a single crystal or a block. The kind of crystalline mobile produced depends on the silicon wafer manufacturing procedure. Crystalline silicon solar cells have dominated the photovoltaic market since the very start of the Nineteen Fifties. Silicon is riskless and abundantly available in the earth's crust, and silicon PV modules have proven their long-time period stability over many years of exercise.

A patient with hyperparathyroidism, a disease where too much pth is produced, would be expected to have a decrease in bone mass and increased calcium levels in the blood.
Explanation:
This results from increased pth levels that cause an excess of parathyroid hormone to be produced (PTH).
PTH throws off the body's normal mineral balance, which can cause lower bone density and more calcium being absorbed from the digestive tract.
<h3>What is hyperparathyroidism and what are its symptoms?</h3>
- One or more of your parathyroid glands may become overactive and secrete an excessive amount of parathyroid hormone if you have hyperparathyroidism (PTH).
- This results in hypercalcemia, a condition where your blood calcium levels increase.
- Chronic fatigue, bodily aches, trouble sleeping, bone pain, memory loss, lack of concentration, depression, and headaches are among the most typical hyperparathyroidism symptoms.
- In addition, kidney failure, hypertension, osteoporosis, kidney stones, and cardiac arrhythmias are all frequently brought on by parathyroid illness.
