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.

In which country do earwigs live?

Earwigs live in the USA and in Europe.

The name earwig, which literally means "ear creature," originated from the widespread superstition that these insects crawl into the ears of sleeping people.

There are twenty-two species of earwigs in the United States, twelve of which have been introduced from other countries. Only four or five species are common pests which invade homes.

The European earwig is a cosmopolitan species which was introduced into North America in the early 1900's.

What are examples of when a solid is transported from one place to another by a fluid?

One example is a slurry such as those used to transport coal or by Syncor to transport petroleum coke. Another would be sedimentation of river water to form a colloid which transports mud or clay downstream.

Can you give me a good example of each of newton's laws plus inertia and conservation of momentum?

well, i can explain the law of inertia. Think of the I turned sideways as a seat belt, because the law is about the safety of wearing a seat belt. If you are in your car going 70 miles on highway and you stop, if you don't have your seat belt on then you are going to fly up.

Why is the bloodhound SSC called the bloodhound SSC?

The Bloodhound SSC is named after the hound dog breed known for its keen sense of smell and tracking abilities, symbolizing the vehicle's pursuit of speed and breaking land speed records. The acronym SSC stands for Supersonic Car, reflecting the car's goal of eventually reaching supersonic speeds.

How do astronomers solve the problems with earth based telescopes?

Astronomers can address issues with Earth-based telescopes by using adaptive optics to correct for atmospheric distortion, selecting observing sites at high altitudes or in deserts with stable air, and designing telescopes with larger mirrors to gather more light and improve image resolution. Additionally, they can employ techniques like interferometry to combine light from multiple telescopes for enhanced resolution.

What scale does the decibel go up in?

The decibel scale is logarithmic, with each increase of 10 decibels representing a tenfold increase in sound intensity. This means that a sound at 20 decibels is 10 times more intense than a sound at 10 decibels, and a sound at 30 decibels is 100 times more intense than a sound at 10 decibels.

What is the scientific words for filtering?

Filtering is the scientific word. Some synonyms are: Synonyms: clarify, clean, distill, drain, dribble, escape, exude, filtrate, leak, metastasize, ooze, osmose, penetrate, percolate, permeate, purify, refine, screen, sieve, sift, soak through, strain, trickle, winnow.

What kind of resource is leather?

Leather is classified as a natural resource. It is also considered to be a renewable resource which is derived from various animals.

How much fresh water is stored in the London aquifer as a percentage?

The London aquifer holds about 18 million cubic meters of fresh water, which accounts for approximately 1% of the total available drinking water supply for London.

What are three types of justification?

  1. Moral justification: Providing reasoning or principles to support a moral or ethical decision.
  2. Legal justification: Providing evidence or reasoning to support a legal argument or decision.
  3. Rational justification: Justifying beliefs or actions based on logical reasoning or evidence.

How does the amount of solute effect the solubility of salt?

If the solution is saturated, then the salt cannot be dissolved in it anymore.

Saturated meaning the solution can no longer dissolve any more of the solute particle.

This is how the amount of solute affect the solubility of salt. More amount, less solubility. Less amount, more solubility.

How do you dissolve a saturated solution without adding water?

One way to dissolve a saturated solution without adding water is by heating the solution. This can increase the solubility of the solute, allowing more of it to dissolve. Another method is by changing the pressure of the system, which can also affect the solubility of the solute. Finally, adding a different solvent that can dissolve both the solute and solvent in the saturated solution can help dissolve the solute without adding more water.

What is an intendent variable?

An independent variable is a factor that is manipulated or controlled by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is being tested or changed to see how it affects the outcome of the study.

What is necessary for all organisms to sustain life?

All organisms require basic needs such as water, nutrients, oxygen, and a suitable environment to sustain life. These essential elements are used for processes such as metabolism, growth, reproduction, and maintaining homeostasis.

Why is radial symmetry is found among aquatic species rather than animals that live on land?

Radial symmetry is advantageous for organisms in water because it allows them to capture food and detect predators from all directions. This type of symmetry is less practical on land where there is more need for mobility and directional movement. Land-dwelling animals have evolved bilateral symmetry to facilitate efficient movement in a single direction.

Vertabrates and invertebrates?

Vertebrates have a backbone or spinal column, while invertebrates do not. Vertebrates include animals like mammals, birds, reptiles, amphibians, and fish, while invertebrates encompass a vast array of animals such as insects, spiders, worms, and mollusks. Vertebrates typically have more complex nervous systems and skeletal structures compared to invertebrates.

Where is hydrophobia most prevalent?

Hydrophobia, or fear of water, can be prevalent in individuals with specific phobias or anxiety disorders. It is not limited to any specific geographical location but can be found worldwide in individuals with such conditions.

Where is yoohoo made?

Yoohoo is made in the United States, with the majority of production taking place in New Jersey.

Do bees have exoskeletons?

Yes. Because bee is an insect. Insects have exoskeletons.

Why do plants grow the best in dark lights?

Plants require a balance of light and darkness for optimal growth. While they do need light for photosynthesis, periods of darkness are also essential for processes like respiration and growth regulation. Too much continuous light can actually be harmful to plants as it can lead to stress and nutrient deficiencies.

What equipment may a rocket carry?

Really anything you want. The only limitation you have is how much weight your rocket can lift. if you exceed that your rocket will, at best, just sit on the launch pad and burn all its fuel off. Remember, every satellite or probe ever put into space was done with really big rockets.

What are the steps to create an organism?

To create an organism, you would need to combine genetic material from two parents through sexual reproduction. The parents pass on their DNA to the offspring, which contains the instructions for development and growth. The organism then undergoes a series of cell divisions and differentiation to grow and develop into a mature organism.

What does fresh water weigh per m3?

Fresh water weighs approximately 1000 kilograms per cubic meter (kg/m3) at standard temperature and pressure.

What chemical indicators are and what they are used for?

chemical indicators are completely an organic solutions that changes color in the solution we added them to it due to the change in PH.....they are used to determine the equevelant point and the end point in titration

Different types of autropods?

Some types of autropods include spiders, scorpions, ticks, and mites. These arthropods belong to the class Arachnida and typically have eight legs, a fused head and thorax, and a segmented body. They are known for their diverse adaptations and predatory behaviors.
