Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

Do gas giants have poisonous atmospheres?

Yes, all the ones in our solar system seem to. Observations of planets in other systems seem to be, also. Theoretically, any planet with a high enough gravity to qualify as a gas giant can retain gases that are poisonous to us, such as hydrogen and helium. Nice article in the link below.

What is constant energy requirement?

Constant energy requirement is the amount of energy needed to maintain basic bodily functions while at rest, also known as the basal metabolic rate (BMR). This energy is necessary to support functions such as heart rate, breathing, and cell maintenance. It does not include energy needed for physical activity or digesting food.

Why is the sun at the way top of the food chain?

Dear Wiki Questioner,

The Sun is way at the top of the food chain because it is the ultimate source of all of the energy consumed in the entire food chain!

The Sun is continually fusing hydrogen molecules into helium molecules which produces a lot of energy in the Sun and makes it very hot. The Sun gets so hot from this fusion energy that it emits large amounts of electromagnetic radiation (Light!) which travels across space and hits the earth.

Plants (with a few exceptions like the Venus Flytrap and the Cobra Lilly) get all the energy they need from the sun's light, which they can "consume" by a process known as photosynthesis.

Herbivores (Plant Eaters), get all of their energy from the plants that they consume, but since the plants get their energy from the sun, we can say that the Herbivores got their energy indirectly from the sun too.

Carnivores (Meat Eaters), get all of their energy from the other animals they consume. Since the other animals get their energy from the plants, who get their energy from the Sun, we can say that the Carnivores also get their energy indirectly to the sun.

So the process is:

Carnivores ---eat---> Herbivores ---eat---> Plants ---Consume---> Sunlight!

The chain always leads back to the Sun, so we say that the sun is on top of the food chain.

Is pushing a box but it doesnt move a balanced or unbalanced force?

There's no such thing as a balanced force or an unbalanced force.

If the entire group of all the forces on an object is unbalanced, then the object
undergoes acceleration, or its "motion changes". If the group of forces on it is
balanced, then its motion doesn't change.

How does monera obtain food?

Monera are single-celled organisms that don't have a nucleus. Bacteria make up the entire kingdom. There are more forms of bacteria than any other organism on Earth. Some bacteria are beneficial to us, such as the ones found in yogurt. Others can cause us to get sick. Also they get nutrients by photosynthesis.

Why is ATP an important in metabolism?

The aim of metabolism is to release energy from substance such as glucose or triglycerides.

ADP (adenosine di phosphate) acts as a carrier and is activated during respiration (another phosphate is added, using a phosphate bond).

When energy is required somewhere in the body (metabolism), the bond is broken, turning ATP into adp and supplying the energy needs. Thus without ATP, there cannot be metabolism.

Why do Shadows move in a curved pattern from morning to afternoon?

Shadows move in a curved pattern because of the Earth's rotation. As the Earth spins on its axis, it creates the appearance of the sun moving across the sky. This changing angle of the sun causes shadows to shift, resulting in the curved pattern you observe from morning to afternoon.

Were can you see the inside of Wizardology online?

"Wizardology" is a book and part of the "Ology" series, which provides interactive content within physical books. To see the inside of "Wizardology," you would need to purchase the book itself, as the content is not typically available to view online.

What are the weather conditions of the planet Saturn?

Weather on Saturn

Like the other gas giant planets, Saturn's atmosphere is mainly hydrogen and helium. Saturn is a windy planet, with 1,000 mile-an-hour winds that do a good job of mixing the atmosphere and making it appear homogeneous through Earth-based telescopes. Saturn's tilt creates seasons and uneven temperatures on the planet. The top of the clouds have an average temperature of -285 degrees Fahrenheit, with warmer temperatures deeper in. A churning hexagonal cloud formation has been spotted near the North Pole and has persisted for a few decades now.

Is it possible to transform a human into a furry?

If you mean by surgery, you can be pretty close. One of the best examples is Stalking Cat

If you mean getting someone to consider themselves "furry", remember that all furries had a time when they had never even heard of the fandom.

Is a Jenny Haniver real?

A Jenny Haniver is a name for a fake mermaid. People fake a Jenny Haniver's existence by ataching different animal bones together and saying that they found a dead mermaid body. Japanese fishermen turned creating Jenny Hanivers into a art form in the 16th century. They used usually a female orangutan head sewed onto a salmon body. Fishermen would say they cought their Jenny Hanivers on their last fishing trip and anyone who didn't Cary a picture of her around would be cursed and would sell the picture to the people. Later, the Jenny Haniver would be sold to muesuems and circuses. This means that the Jenny Haniver is a hoax.

Why was asbestos used as roofs for houses?

Asbestos was used as roofs for houses because it is fire-resistant, durable, and has good insulating properties. However, it was later discovered that exposure to asbestos fibers can lead to serious health issues such as lung cancer and mesothelioma, leading to its ban in many countries.

What are the three types of carbohydrates and what are there uses?

The first type of carbohydrate is a monosaccharide. Monosaccharides include glucose, galactose, fructose, and ribose - all of which are essential for basic cellular function. Monosaccharides generally look like a 'ring' of carbon atoms with oxygen and hydrogens branching off from the central carbon skeleton.

The second type of carbohydrate is a disaccharide. Disaccharides are made of two monosaccharides linked together through an oxygen atom. Some examples are sucrose and lactose, which humans regularly digest as part of their diet.

The last type of carbohydrate is a polysaccharide. Polysaccharides are chains of monosaccharides that are longer than two 'rings' long. Polysaccharides are used for energy storage (such as glycogen in animals and amylopectin in plants), as well as structure (such as cellulose in plants and chitin in some arthropods).

Do moon phases change each day?

yes, the moon phases change every day. as long as the moon keeps orbiting earth, that will happen.

Why was asbestos used in roofs for houses?

Asbestos was chosen as a component in structural materials because of its relative abundance, its stability to chemical attack, and its ability to remain unchanged over a wide range of environmental conditions. Its fibrous shape also made it useful as a material to strengthen otherwise brittle materials like cement and tile. The very things that cause it to be a problem in the human body - its fibrous nature, and its immunity to chemical attack, were characteristics that made it useful as a building material.

If you study stars as your career what would you be called?

A person who studies the stars is called an astronomer. They partake in the branch of study that is called astronomy.

If he specializes in the physics of the stars, he would be an astrophysicist.

How do spacecraft takeoff?

In the rocket engine large amount of fuel are burnt. The burning fuel expands and is forces itself out the bottom of the rocket.

As it pushes down, it pushes the rocket up. If the force pushing the rocket up exceeds its weight, the rocket will take off.

When did Apollo 11 lift off from the moon?

Apollo 11 lifted off from the moon on July 21, 1969. The ascent stage of the lunar module carrying astronauts Neil Armstrong and Buzz Aldrin successfully docked with the command module piloted by Michael Collins before beginning its journey back to Earth.

What you call a vast group of stars?

A vast group of stars is called a galaxy. Galaxies are large systems of stars, gas, dust, and dark matter, bound together by gravity. The Milky Way is an example of a galaxy that contains our solar system.

How many stages of a rocket are there?

Typically, a rocket can have multiple stages, ranging from two to four stages. Each stage is responsible for providing thrust during a specific portion of the ascent to space, with each stage being jettisoned once its fuel is depleted. As each stage is discarded, the rocket becomes lighter and more efficient for reaching its target orbit.

Could cellular respiration work without photosynthesis?

Yes, and it does all the time, but some other energy source is required. For one thing, all animal cells undergo cellular respiration without photosynthesis, as do all anaerobic bacteria (yeasts, etc.), and many plants and animals that grow on thermal vents on the bottom of the ocean. Instead of getting energy from light, they use chemical energy (animals and yeasts) or geothermal (heat) energy, such as in the case of aquatic organisms on heat vents.

Is the magnetic pole another name for the south pole?

No.

The Earth is a spinning sphere, and the axis of the rotation matches the Earth's surface at the north pole and the south pole. If the Earth had an axle, that's where they would poke out.

The Earth is also a giant magnet, like an enormous bar magnet. The orientation of this magnet, and the magnetic lines of force from it, are not lined up with the physical axis of the Earth's rotation. The "north magnetic pole" is somewhere in northern Canada, while the south magnetic pole is in Antarctica.

When navigating with a magnetic compass, the compass doesn't point at the north pole; it points to the north MAGNETIC pole. In most of Europe, there wasn't a whole lot of difference, but in North America, the difference between true and magnetic north can be dozens of degrees. Navigational maps will list lines of "magnetic variation", which is the difference between true north and magnetic north, so that you can apply the appropriate correction.

Are lunar mares younger than the craters that sit in them?

Yes, lunar mares are younger than the craters that formed in them. Lunar mares are vast, flat areas filled with solidified lava flows, while craters are formed by impacts from meteoroids. The dark-colored mare areas are generally younger because they filled in older, pre-existing craters.

Which country produces the most solar energy?

China produces the most solar energy in the world. It has the largest installed capacity of solar energy and is also the largest producer of solar panels globally.

What is the light of fire a symbol of?

The light of fire is often seen as a symbol of illumination, transformation, and energy. It can represent knowledge, passion, and power.
