Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.
How can we use patterns on the periodic table to predict an element’s structure and reactivity?
Answer:
The atomic number of an element which gives it valency.
From the valency, we get the ionic charge.
The greater the ionic charge, the greater the reactivity.

List the following units of time from shortest to longest: age,eon,epoch,era,period, and year
Answer:
year, age, epoch, period, era, eon
Explanation:
The shortest to longest geological time scale units are year, age, epoch, period, era, eon
What is geological time scale?It is the calendar of Earth's historical events. The time scale sub- divided into units of abstract time such as eons, eras, periods, epochs, ages, years.
The geologic time scale is measured based on observable characteristics of different layers on rock surface formed during various time periods and fossils present in every layer.
Dating is the most common method to measure over the time and the most advanced method stratigraphy and geochronology in which any time scale be periodically updated.
Other way to also classify different segment of geological time scale are either by using data of the occurrence of major geologic events and the appearance or disappearance of valuable life-forms.
Hence the correct order from shortest to longest time scale are year, age, epoch, period, era, eon

4. always produces genetic disorders.
Please help I’ll give brainly
Answer:
The exchange of segments of DNA between the members of a pair of is called crossing
hope it is helpful to you
The exchange of segments of DNA between the members of a pair of chromosomes acts as a source of variations within a species. Therefore, the correct option is A.
Genetic recombination, also called crossing over, occurs when DNA segments from one chromosome are exchanged for those of another. This process has several important implications for genetics. It serves as the primary source of genetic diversity within a species. New allelic combinations arise as a result of the exchange of DNA segments between homologous chromosomes during crossing over.
Therefore, the correct option is A.

Considering the origins and processes involved in how natural gas, petroleum, and coal formed, which of the following is the best explanation regarding
why these resources are referred to as fossil fuels?
Natural gas, petroleum, and coal were formed by breaking open rocks that contain fossils from millions of years ago.
Natural gas, petroleum, and coal were only formed during the Jurassic period when dinosaurs walked the Earth.
Natural gas, petroleum, and coal were formed when organic matter that has been buried deep in the Earth was subjected to heat and pressure
over millions of years.
Natural gas, petroleum, and coal were formed when elements came together to form planet Earth billions of years ago.
Answer:
The fossil fuels on Earth were formed well before the presence of dinosaurs, which is why they are called fossil fuels. Fossil fuels were formed in the Earth's crust out of dead organisms that lived hundreds of millions of years ago

For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain why it does not fit.
1. Coal, Oil, Solar, Power, Natural Gas
2. Biodegradable, Recycling, Sustainability, Deforestation
Answer: the words that doesn't belong include:
1.) Power
2.) Deforestation
Explanation:
1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.
Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.
2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.
Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.
