Answer:1).A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
2)Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals.
3)Coal is a very useful rock that formed over millions of years from the ... No, coal is not a mineral because coal is made of dead plants.
4)The relatively cheap cost of fossil fuels is a major positive aspect. They are in abundant supply, which makes them inexpensive to drill or mine for. In particular, coal is one of the most widely available fossil fuels.
5)High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.

Introduction
What was the purpose of the experiment?
The purpose of this experiment is to create CO2, also known as carbon dioxide, and observe chemical reactions.
How can you identify the gas produced in a chemical reaction without observing the atoms and molecules directly? Explain.
If I look at how the gas would react or its qualities, I can identify the gas without having to observe its atoms directly.
Write a hypothesis based on observations and scientific principles.
I hypothesize that the mixture produced carbon dioxide, an acidic and colorless gas. In addition to organic materials, such as leaves and dirt, carbon dioxide is also produced when they decay.
Experimental Methods
What tools or materials did you use to collect your data?
To conduct my experiment, I used a glass cup, baking soda, vinegar, paper to record my observations, and a match.

a singularity
a super spiral galaxy
a mass of antimatter
the answer is a black hole
The universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.
What is the Big bang?The big bang may be defined as the cosmic explosion that significantly marked the initiation of the universe according to the big bang theory. The origin of the universe is explained by the Big Bang theory.
At initial, the whole universe appeared like a black hole where no life is present. It was all the dark around each and every corner. The universe was an infinite stretch of ultrahot, dense material and everything consisted of empty space.
Before the big bang, the universe was almost infinitely small, dark, and a size less than a trillionth of a second. It was a period of inflation which is followed by a more catastrophic event which was violent, and known as the period of expansion.
Therefore, the universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.

What's the definition of epista
sis
Epistasis is genetic phenomenon that is defined by an interection of genetic variation loci
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
The interplay of genes that determines phenotype is known as epistasis. Genes may either hide each other, making one "dominant," or they can mix to create a new characteristic. It's the conditional link between two genes that can determine a single phenotype for certain features.
Epistasis is a term used in genetics to describe the interaction of genes at two or more loci, as a consequence of which the gene's impact is influenced by the presence of one or more modifier genes. One gene or allele in the interaction is obscuring the phenotypic expression of the other genes or alleles. Epistatic refers to the gene or allele that masks the impact. The other gene(s) or allele(s) being masked, on the other hand, is/are referred to as hypostatic. Epistasis can be dominant or recessive. The fur colour of Labrador retrievers, which is a polygenic feature, is an example of epistasis. Its fur colour is determined by the interaction of two genes.

Describe the elements and compounds of coal being mined
Answer:
The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements
Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.
Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.
Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.

6. Why can't water be used to dissolve the
caffeine found in coffee and tea?
Alcohol is used to extract caffeine
Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.
What is solubility?The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.
Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.
It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.
Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.
Thus, water can not be used to dissolve the caffeine found in coffee and tea.
