Name the three common states of matter on earth.
Which states of matter have a set shape? Explain why this is, based on the animations you observed for the different states of matter.
Which states of matter have a set volume? Explain why this is, based on the animations you observed for the different states of matter.
The boiling point is the temperature at which a liquid substance will turn to vapor, and also the temperature at which vapor will condense to a liquid. The boiling point of ethanol is about 80°C, and the boiling point of water is about 100°C.
What can you conclude about the intermolecular forces in water and ethanol?
Do you predict water freezes at a higher temperature or at a lower temperature than ethanol?
Recall how different Van der Waals attractions and how ionic charges changed the movement of atoms in the animation. Do you think that Van der Waals attractions or ionic charges are stronger? Why?
1. solid, liquid and gas
2.Solid can move but gas and liquid is more flexible than solid. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid is flexible.
3.Among the 3 state, solid has a fixed volume while liquid takes the volume of its container. When gas is compressed, it takes the volume of its container likewise.
the answer is solid, liquid and gas
Answer:
1. Liquid, Solid, Gas
2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.
3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.
4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.
B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point
5. Ionic charges are stronger.
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

Why do most food chains only two, three or rarely ,four consumers after the green plant producer?
Answer:
It is rare to find food chains that have more than four or five links because the loss of energy limits the length of food chains. At each trophic level, most of the energy is lost through biological processes such as respiration or finding food
Explanation:
Answer:
Because so much energy is lost to life processes.
Explanation:
As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:
M ovement
R espiration
S ensitivity
G rowth
R eproduction
E xcretion
N utrition
This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!
All cells in the body have the same genome, with a couple of exceptions. What are these exceptions?
Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

Water takes a longer time to change temperature than alcohol does because water requires a larger amount of heat to be absorbed to cause the change.
()True
Or
()False
Answer:
True
Explanation:
Water freezes faster than alcohol due to lower freezing point.
Water takes less time to freeze than alcohol but can absorb a large amount of heat with only a small change in its temperature. Alcohol has -114.7 degrees Celsius of freezing temperature whereas water has freezing point of 0 degrees Celsius.
The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.
Why water freezes faster than alcohol?Alcohol takes longer to freeze than water, but water can absorb a lot of heat with just a slight change in temperature. Water has a freezing point of zero degrees Celsius, but alcohol has a freezing point of -114.7 degrees Celsius.
Because water molecules must be forced to move more quickly within the water in order for the temperature to rise, water is more able to absorb heat than many other substances. As a result, water freezes more quickly than alcohol.
Therefore, The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.

Why are braided streams common in sedimentary rocks before the arrival of plants on land ?
Answer:
Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).

do you think carbon sinks can ever completely reverse global warming, why or why not?
Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?
Name three reasons, as to why, bacteria is so widespread into different life/ecosystems
Answer:
Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria.The most influential bacteria for life on Earth are found in the soil, sediments and seas. Well known functions of these are to provide nutrients like nitrogen and phosphorus to plants as well as producing growth hormones. By decomposing dead organic matter, they contribute to soil structure and the cycles of nature. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Explanation:
What occurs if kelp is not present to absorb CO2 or produce O2?
there won't be fresh oxygen and CO2 will be dangerous for out health and we may not have some of the energy that we have today because kelp also can produce energy.
All other living organisms in the aquatic environment will be negatively affected if Kelp is not present to absorb CO2 or produce O2.
ROLE OF PHOTOSYNTHESIS:
Kelp are living organisms in the kingdom Protista, which possess the ability to photosynthesize or use energy from sunlight to produce food. Photosynthesis is a process that absorbs CO2 from the atmosphere and release O2 as a gaseous product. Kelp is a producer of aquatic environment, which means it helps to absorb CO2 and release O2 into the atmosphere. This O2 is used for cellular respiration by other living organisms. If kelp is not present to absorb CO2 or produce O2, other other living organisms in the aquatic environment will be negatively affected.Learn more about the role of photosynthesis at: https://brainly.com/question/1388366?referrer=searchResults

Explanation:
Long before the structure of DNA was solved, the physicist Erwin Schrodinger suggested that the three-dimensional arrangement in some polymer had to explain the two main properties of heredity: 1) the stability of life, such that traits were passed faithfully from generation to generation, and 2) the mutability of life, such that traits could change. How did Watson and Crick’s structure explain those two properties?
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
