The scientific name for the human windpipe is the trachea.

900 ml / liter carbon bi oxide is dissolved in water but only 4 ml/ liter of Oxygen is dissolved in water so carbon bi oxide is transported through solution in plasma but Oxygen is not and so one of the most wonderful molecule is required for it's transport, that is Hemoglobin, witch transport 70 times as more Oxygen.

Well, they are technically still forming, but fossil fuels form over millions of years. We call it non-renewable because there is no way for us to form more of it ourselves in our lifetimes. If we use it all up, it is gone, and we won't be alive when another big supply of it would be available.

Earth's tilt causes the different seasons by changing the angle at which sunlight hits the Earth's surface. This variation in sunlight intensity creates differences in temperature and weather patterns across the globe. Regions closer to the poles experience more extreme seasons due to the tilt of the Earth's axis.

A biological puzzle is a scientific question or phenomenon that challenges our current understanding of biology, genetics, or evolution. It usually involves complex or unexpected observations that cannot be easily explained by existing theories or frameworks. Scientists investigate these puzzles to uncover new insights and expand our knowledge of the natural world.

Frozen water vapor on a surface is called frost. It forms when water vapor in the air comes into contact with a surface that is below freezing temperature, causing it to freeze and form ice crystals.

The scientific name for heart failure is "congestive heart failure" or "cardiac failure." It is a condition where the heart is unable to pump blood effectively to meet the body's needs.

The process in which huge forces from inside the Earth push rock upwards is called uplift. This can result from tectonic plate movements, volcanic activity, or other geologic processes that cause rocks to move vertically towards the surface. Uplift can lead to the formation of mountain ranges, plateaus, and other elevated landforms.

DNA sequences are more similar in closely related organisms because they share a common ancestor and have undergone fewer genetic changes over time. As organisms diverge and evolve, mutations accumulate in their DNA, leading to differences in their genetic sequences. Therefore, closely related organisms have had less time to accumulate mutations, resulting in more similar DNA sequences.

Human activities can contaminate groundwater and surface water through the release of pollutants such as chemicals, fertilizers, and sewage. Deforestation and urban development can alter the natural flow of water, leading to erosion and sedimentation in water bodies. Over-extraction of groundwater for agricultural and industrial purposes can also disrupt the balance of groundwater levels and impact surface water sources.

Three natural resources from the Earth's crust are coal, iron ore, and copper. These resources are commonly mined and utilized for various industrial processes, including energy production, manufacturing, and construction.

You generally find older crust on the east coast compared to the west coast. This is because the east coast tends to have continental crust, which is thicker and older than the oceanic crust found on the west coast.

Millions of years ago, there was more oxygen in the atmosphere due to high levels of photosynthesis by ancient plants. These plants absorbed carbon dioxide and released oxygen as a byproduct, leading to higher oxygen concentrations in the air.

Humans have been on Earth for approximately 0.2% of Earth's history, which is estimated to be around 4.5 billion years. This means humans have been around for about 200,000 years.

Thermal stratification is the term that describes the layering of water caused by differences in temperature. This phenomenon is common in lakes and oceans, where warmer, less dense water floats on top of cooler, denser water, creating distinct layers based on temperature.

In an airplane, you are still affected by Earth's gravity as the plane is flying against the pull of gravity, creating lift and keeping you pressed down towards the floor. In an orbiting spacecraft, you are in free fall around Earth, so you and the spacecraft are falling towards Earth at the same rate hence you experience weightlessness.

Biomass is considered a better alternative to oil because it is a renewable resource that can be replenished relatively quickly. It also helps reduce greenhouse gas emissions and is more sustainable in the long term compared to finite fossil fuels like oil. Additionally, biomass can be produced locally, reducing the need for long-distance transportation and supporting local economies.

When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.

The early atmosphere of Earth was composed primarily of gases like carbon dioxide, water vapor, nitrogen, and trace amounts of methane and ammonia. There was very little oxygen present in the atmosphere during this time. Volcanic activity played a significant role in shaping the early atmosphere, releasing gases that contributed to its composition.

Indeterminate growth refers to a pattern of growth where an organism continues to grow throughout its life, with no set endpoint. This type of growth is commonly seen in plants and some animals, allowing them to increase in size indefinitely.

The process you're referring to is called crystallization. This is when a liquid solidifies into a solid state due to a decrease in temperature.

Bacillus Cereus is a rod bacteria.

Found in dry cereals it is a common cause of exotoxin associated gastroenteritis.
