How many hours does the average person spend dreaming each night?

• About 80 minutes
• About 15 minutes
• About one hour
• About two hours

Researchers estimate that the average person spends about two hours dreaming each night. However, dream content research relies on self-reported information, which can be unreliable. Also, not all people remember their dreams after waking. This memory gap makes it challenging for researchers to accurately estimate the duration of each dream or deduce whether the perceived length of a dream matches how long the dream actually lasted.

What is considered the average normal body temperature for an adult?

• 80.6 F
• 86 F
• 98.6 F
• 105.8 F

Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6 F (37°C). Some studies have shown that the "normal" body temperature can have a range from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness. Body temperature normally changes throughout the day. In adults, it is lowest in the early morning.

How long does it take human taste buds to fully regenerate on average?

• 2 years
• 10 days
• 20 minutes
• 3 months

Taste buds are cells on your tongue that allow you to perceive tastes, including sweet, salty, sour, bitter, and umami. They’re located inside the tiny bumps covering your tongue called papillae. Taste buds regenerate approximately every 10 days, which means injured taste buds usually repair on their own. Basal cells develop into new taste receptor cells every week or two (10 days on average). Our taste buds decrease as we age, which means that your perception of taste changes at different stages of life. The foods you love as an adult may differ from those you love as a child. Similarly, taste perception changes as you transition through adulthood.

Which planet has the highest average temperature?

• Venus
• Mars
• Jupiter
• Earth

Venus is the second closest planet to the Sun, and it has the highest average surface temperatures – reaching up to 860 F° (460 °C) regularly. One of the reasons for that is Venus’ proximity to the Sun, being just on the inner edge of the habitability zone, but also to Venus’ thick atmosphere, which is composed of heavy clouds of carbon dioxide and sulfur dioxide.

On average, how many full moons are there in a single month?

• 1
• 3
• 4
• 6

The Moon’s phases and the months of the year are inextricably linked. It takes the Moon about 29.5 days to go through all of its phases, meaning that each month has on average 1 full moon (which occurs when the entire face of the Moon is illuminated by the Sun). Because our modern calendar isn’t quite in line with the Moon’s phases, sometimes we get more than one full moon in a month. This is sometimes known as a blue moon. Over time, different cultures have given names to full moons across the lunar calendar. Many of the Moon’s nicknames have come to us from Native American culture because, for their way of life, the cycles of the lunar phases were just as important a method of timekeeping as the longer solar cycle of the year.

Which U.S. state has the highest average elevation?

• Oregon
• Idaho
• Utah
• Colorado

Colorado is the highest state in the United States, with an average elevation of 6,800 feet above sea level. The United States has an average elevation of roughly 2,500 feet above sea level, however there is a stark contrast in elevations across the country.The 10 states with the highest average elevation are all in the western region of the country, as this is, by far, the most mountainous region in the country. The largest mountain ranges in the contiguous western states are the Rocky Mountains, Sierra Nevada, and Cascade Range, while the Appalachian Mountains is the longest range in the east - however, the highest point in the U.S. is Denali (Mount McKinley), found in Alaska.

How long can a person survive without water on average?

• 3 days
• 12 hours
• 1 day
• 30 days

The body needs lots of water to carry out many essential functions, such as balancing the internal temperature and keeping cells alive. As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this.

How much does an adult human brain weight on average?

• 3 pounds
• 10 pounds
• 20 pounds
• 15 pounds

The average adult human brain weighs about 3 pounds (1300 to 1400 grams). A newborn human baby's brain weighs approximately 350 to 400 grams or three-quarters of a pound. The average brain is around 15 centimeters long. Neurons are the building blocks of the brain and nervous system. They transmit and carry information, allowing different parts of the brain to communicate. They also allow the brain to communicate with other parts of the body. Researchers currently estimate that there are around 86 billion neurons in the human brain.

How long can a sperm whale hold its breath underwater on average?

• 90 minutes
• 15 minutes
• 2 days
• 7 hours

The longest-ever recorded dive by a whale was made by a Cuvier's beaked whale. It lasted 222 minutes and broke the record for diving mammals. Other whales can also hold their breath for a very long time. A sperm whale can spend around 90 minutes hunting underwater before it has to come back to the surface to breathe. In 1969, a male sperm whale was killed off the coast of South Africa after surfacing from a dive lasting 117 minutes. Whales' lungs are particularly efficient at taking up oxygen when they breathe air in and out through their blowholes at the water's surface. Special adaptations help them hold their breath for a long time.

Which U.S. city receives the most average annual snowfall?

• Boulder, Colorado
• Erie, Pennsylvania
• Flagstaff, Arizona
• Syracuse, New York

While the snowbirds typically migrate south for the winter, the snow fanatics tend to flock to northern areas of the U.S. to get their winter weather fix. But some cities stand out for the amount of snow they offer to their inhabitants and visitors. Syracuse, New York, takes home the crown as the snowiest city in America, averaging 127.8 inches each winter. That's shy of 11 feet of snow, most of which is courtesy of the large body of water to its northwest: Lake Ontario.

How many hours do wild elephants sleep at night on average?

• 2 hours
• Half an hour
• 13 hours
• 10 hours

Wild elephants average just 2 hours of sleep a night, making them the lightest-known snoozers of any mammal. Previous studies have looked at such habits in captive elephants, which sleep for 3 to 7 hours a day. But with more dangers and pressure to find food, wild animals tend to sleep less. So Paul Manger at the University of the Witwatersrand, Johannesburg in South Africa and his colleagues set out to monitor sleep in wild African elephants in Chobe National Park in northern Botswana. The team monitored two matriarchs for 35 continuous days. The elephants slept for an average of 2 hours a night, not in a single slumber but in four to five short bursts – a pattern known as polyphasic sleep. Most of their sleep occurred between 1.00 and 6.00 am, and the elephants snoozed in different places every night.

How many turkeys are sold each Thanksgiving on average?

• 5 million
• 11 million
• 200 million
• 45 million

Americans buy about 45 million turkeys for Thanksgiving every year. Even if not every home celebrates Thanksgiving with the typical turkey, many Thanksgiving celebrations still involve this particular poultry. The amount of turkeys consumed in America has decreased a bit between 2017 and 1998, but it has remained consistently around 240 million for the last decade. According to the University of Illinois, "In 1920, U.S. turkey growers produced one turkey for every 29 persons in the U.S." Today, that number is closer to a turkey per person,

How many dimples are there on an average golf ball?

• 166
• 336
• 576
• 1206

Not all golf balls are the same; there is no one-size-fits-all. Golf balls have dimples, which are small indentations on the surface that look like mini craters. The dimple pattern on a golf ball affects a whole host of factors, such as air resistance, distance, and trajectory. These dimples vibrate the air around the ball when it is in the air, reducing drag. With the dimples, the ball travels further than it would if the dimples were not present. The average golf ball has 336 dimples, and all of them must be symmetrical.

What is the average length of a human pregnancy?

• 50 Weeks
• 20 Weeks
• 40 Weeks
• 30 Weeks

Pregnancy lasts for about 280 days or 40 weeks. A preterm or premature baby is delivered before 37 weeks of your pregnancy. Extremely preterm infants are born at 23 through 28 weeks. Moderately preterm infants are born between 29 and 33 weeks. Late preterm infants are born between 34 and 37 weeks. Babies born before 39 weeks have a greater chance of breathing problems, low blood sugar, and other problems that may result in being admitted to a neonatal intensive care unit (NICU).
