Mostly decaying organisms are needed to present in marine mud to form fossil fuels.
Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.
Which of the following is not true about runoff?
A
Runoff is all the water in lakes and streams that isn’t evaporated by the sun.
B
Runoff can bring chemicals and nutrients from the land into lakes and streams.
C
Runoff is water from precipitation that isn’t absorbed into the ground.
D
Runoff flows across the surface of the land rather than underground.
Answers
Answer:
A is the answer
Explanation:
See, let me explain it first of all.
Because, We all know every drop of water is being evaporated from the seas, streams, oceans,etc. So, the statement is wrong about it. It is wrong. How can't water get evaporated from the seas and the streams,etc.
I wish you got a helping hand from me. If it helps don't forget to like and mark me
The statement which is not true about Runoff is as follows:
Runoff is all the water in lakes and streams that isn’t evaporated by the sun.Thus, the correct option for this question is A.
What do you mean by Runoff?Runoff may be defined as the excessive flow of water which is caused by precipitation that can not be absorbed by the land very efficiently. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.
Runoff can come from both natural processes, as well as, human activities. It brings chemicals and nutrients from the land that spread on the agricultural fields into lakes and streams.
A single drop of water can be easily evaporated by the sun. So, this runoff is also effectively evaporated by the sun and makes the land completely dry gradually with a time duration depending on the severity of the runoff.
Therefore, the correct option for this question is A.

Answers
Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.
The National Human Genome Research Institute (NHGRI), a part of the National Institutes of Health (NIH), provides a fact sheet Deoxyribonucleic Acid (DNA) that gives an introduction to this molecule.
StatedClearly offers a video introduction to DNA and how it works.
The New Genetics, a publication of the National Institute of General Medical Sciences, part of the NIH, discusses the structure of DNA and how it was discovered.
A basic explanation and illustration of DNA can be found on Arizona State University's "Ask a Biologist" website.
The Virtual Genetics Education Centre, created by the University of Leicester, offers additional information on DNA, genes, and chromosomes.
An overview of mitochondrial DNA is available from the Neuromuscular Disease Center at Washington University in St. Louis.
The shape of the DNA molecule is called a double helix. The backbone of DNA is made of sugar molecules and phosphate molecules. The "rungs" of DNA are made of four nitrogen bases that are adenine, thymine, guanine, cytosine.
What is DNA ?The molecule found inside cells that contain the genetic information necessary for an organism's development and function. DNA molecules enable this information to be passed down from generation to generation.
DNA is made up of a series of molecules known as nucleotides. A nitrogen base, a sugar group, and a phosphate group are all present in each nucleotide. Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) are the four nitrogen bases that can be found in DNA (C). There are billions of DNA bases in human DNA.
It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes.
Thus, chromosomes are composed of thousands of shorter DNA segments known as genes.

In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answers
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.

What is the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis according to the balanced equation: 2H2O yields 2H2 + O2
Answers
Taking into account the reaction stoichiometry, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.
Reaction stoichiometryIn first place, the balanced reaction is:
2 H₂O → 2 H₂ + O₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
H₂O: 2 molesH₂: 2 molesO₂: 1 moleThe molar mass of the compounds is:
H₂O: 18 g/moleH₂: 2 g/moleO₂: 32 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
H₂O: 2 moles ×18 g/mole= 36 gramsH₂: 2 moles ×2 g/mole= 4 gramsO₂: 1 mole ×32 g/mole= 32 gramsDefinition of theorical yieldThe theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theorical yield of O₂The following rule of three can be applied: if by reaction stoichiometry 36 grams of water form 32 grams of oxygen, 29.2 grams of water form how much mass of oxygen?
\(mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}\)
mass of oxygen= 25.956 grams
Finally, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.
