What is fossilized poop called?

Fossilized poop is called coprolite. It is formed when feces undergoes a process of mineralization and becomes preserved in rock. Coprolites can provide valuable insights into the diet and digestive processes of ancient animals.

Can rubbing alcohol take out permanent marker?

isopropanol/Ispropyl (or called rubbing alcohol) is a solvent that has polar molecules (molecules with a positive charged molecule that sticks to a negative charged molecule).

If you sniff a sharpie, it has a sharp, alcohol smell, right? Sharpies have n-propanol alcohol, n-butanol, and diacetone alcohol in them. They have pretty similar structures to rubbing alcohol. All alcohol have polar molecules.

There is a "like dissolve like" rule. This means Polar solvent+Polar solvent will stick together. OR non-polar solvent+nonpolar solvent will stick together.

The closer the types of molecule and chemical make-ups are, the more likely they are to dissolve or be removed.

What might happen if there was an earthquake near a mountain?

If there is an earthquake near a mountain, the shaking can trigger landslides, rockfalls, and avalanches on the mountain slopes. The earthquake can also cause the formation of cracks or fractures in the mountain, potentially leading to increased instability in the area.

How many kilometers in a 5 miles?

Answer: 5 mi. = 8.0km. Exactly..

On a track

400m = 1 lap.

2.5 laps = 1km or 1000m.

2.5*8 laps is 20 laps. Since 20 laps = 8 km. That must mean that

5 miles = 8k exactly.

and 5k is 3.125 miles too.

What does a breeder reactor produce?

Well, simply put, both are nuclear reactors. A breeder reactor is one which instead of losing it's neutron production to capture in moderators or shielding elements, absorbs most of the neutron production in the fuel specifically for the production of transuranic elements.

Such reactors have been used since the 60's to facilitate in the production of fusion nuclear weapons, also known as hydrogen bombs, as these require large amounts of plutonium which can only be created in a breeder reactor.

The U.N. has been discouraging the use of breeder reactors since the mid nineties and many worldwide have been shut down. This is in part due to their use in the proliferation of nuclear weapons and due to their inherent instability.

There are literally dozens of types of nuclear reactors, breeders being only one. Others include pressurized water reactors, boiling water reactors, graphite moderated reactors, lead cooled reactors, or the more recent pebble bed reactors.

Why do scientists use equipment?

Scientists use equipment to conduct experiments, make observations, collect data, and analyze results with accuracy and precision. Different types of equipment help scientists measure, record, manipulate, and visualize physical and chemical phenomena to understand the natural world better.

Why do you need to procreate?

Procreation is essential for the survival of the human species and continuation of our genetic lineage. It allows for the passing on of traits and characteristics to future generations, ensuring the diversity and evolution of the population. Additionally, for many individuals, parenthood can bring a sense of fulfillment, purpose, and connection to something greater than themselves.

What is the definition of the plant part style?

The style is the narrow, elongated part of the pistil in a flower that connects the stigma to the ovary. It serves as the passage for pollen to reach the ovary during fertilization.

What makes a dichotomous key easy to use?

A dichotomous key is easy to use when it has clear and simple descriptions of the characteristics being used to identify organisms. It should also have easy-to-follow decision points that lead users to the correct identification. Additionally, having well-organized and visually appealing formats can enhance ease of use.

What is the difference between solid and gas?

Solids have a fixed shape and volume, with particles that are closely packed and vibrate in fixed positions. Gases have no fixed shape or volume, with particles that are far apart and move freely at high speeds.

How do organisms use chemical energy to do work?

*Energy is the capacity to do work or cause change* Organisms store energy in organic molecules as chemical energy* Free energy is the portion of energy released during chemical reactions that is available to do work* -

Who is Frank Winters?

Frank Winters is a former American football player who played as a center in the NFL for the Green Bay Packers. He won the Super Bowl with the Packers in 1997. After retiring from playing, Winters has worked as a coach and broadcaster.

What is the cost of making a Breeder Reactor?

Breeder reactors have only been made as experiments or prototypes so far, by government supported agencies, so the cost to make one commercially is not available. It is significant though that various trials in different countries, the US, UK, and France for example, after being supported expensively for some years, have been abandoned. This doesn't mean breeders are complete failures, but at the present time they don't compete with straight thermal fission reactors using enriched uranium fuel, and the benefits of breeding don't outweigh the disadvantages. This situation will probably change in the future as U235 gets scarcer, but this point is perhaps 50 years away.

Would plants with fibrous roots or taproots be more suitable for planting in a windy area?

Plants with fibrous roots are generally more suitable for planting in a windy area because they spread out horizontally, creating a dense network that helps anchor the plant securely in the soil. Taproot systems, on the other hand, have a single large root that may be more easily uprooted by strong winds.

Name all the labeled land and water areas that intersect with the equator?

The land areas that intersect with the equator are Ecuador, Colombia, Brazil, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Indonesia, and Kiribati. The water areas that intersect with the equator are the Atlantic Ocean, the Pacific Ocean, and the Indian Ocean.

Where in the UK does frontal rainfall mostly occur?

Frontal rainfall in the UK mostly occurs in the western regions due to the prevailing westerly winds bringing moist air from the Atlantic Ocean. Areas such as western Scotland, western Wales, and the west of England receive higher amounts of frontal rainfall compared to the eastern regions.

Surface tension of water on adding detergent?

Well If you have a pie pan filled with milk and then drop 4 diffrent colors of food coloring droped in but not touching then get a tooth pick with detergent on it and touch it in the foodcoloring will swirl out like tie die in the pan.

What is cgs units of velocity?

cgs means centimeter,gram,second.

cgs unit of velocity is cm/s.

What roles do models play in testing hypotheses?

a BIG role...too big in some case which have left egg on their faces (scientists) on more than one occasion, and have created big problems for the world in a number of ways.

Bad data in...bad data out!

How is air quality measured in the UK?

Air quality in the UK is measured using a network of monitoring stations that measure various pollutants such as particulate matter, nitrogen dioxide, and ozone. The data collected from these stations is then used to calculate air quality indices which provide information on the level of pollution in the air and its potential effects on health. This information is made publicly available to raise awareness and inform actions to improve air quality.

Why is it easier for some organisms than others to survive when a food item disappears from their environment?

Organisms that have a diverse diet or flexible feeding habits are more likely to survive when a food item disappears from their environment, as they can adapt and switch to alternative food sources. Additionally, organisms with efficient energy storage mechanisms or lower metabolic rates may also be better equipped to endure food scarcity. Conversely, organisms that rely heavily on a single food source or have specialized feeding requirements may struggle to survive if that food item disappears.

How long can a bird of prey live?

Birds of prey can live anywhere from 10-30 years, depending on the species. Larger species tend to have longer lifespans compared to smaller species. Proper care, habitat, and diet also play a significant role in determining the lifespan of a bird of prey.

How are acceleration velocity and deceleration related?

Acceleration and deceleration are both related to changes in velocity. Acceleration refers to an increase in velocity, while deceleration refers to a decrease in velocity. Both involve changes in speed over time, with acceleration increasing speed and deceleration decreasing speed.

Preventing heat loss by radiation and conduction?

To prevent heat loss by radiation, you can use insulating materials like fiberglass or foam to create a barrier that reflects the heat back into the space. To prevent heat loss by conduction, you can use materials with low thermal conductivity, such as wood or foam, to reduce the transfer of heat through solid materials. Proper sealing of gaps and cracks in doors, windows, and walls can also help minimize heat loss by conduction.
