ANSWER:
Based on the "principle of Superposition", the geology student can say that the layers on top are "younger" than the layers present below.
EXPLANATION:
The principle of superposition is a basic principle in geology which states that in a "sequence of strata", any stratum is "younger" than the one on which it "rests". Sedimentary rocks are formed by deposition of "one layer on top of another". Therefore, the "layers at the bottom will be older" than the layers of rocks that form above the lower ones.Ecologist Mark is trying to identify the type of pollution that caused excessive algae growth on a river and killed fishes and plants.

which information must be known about a compound to find the molecular formula from the empirical formula
Answer:
Molecular mass or vapor density
Explanation:
The empirical formula is the simplest formula of a compound. The molecular formula expresses the exact formula of the compound. To derive the molecular formula, we need information about its molecular mass or if given the vapor density.
(Empirical Formula)n = Molecular formula ------(i)
n = number of repeating units of the empirical formula present in one mole of the molecule
also, (molar mass of empirical formula)n = molar mass of compound
From here, we can find n and insert in (i) above.

wich of the following is an example of an epeirogenic process
Answer:In geology, epeirogenic movement (from Greek epeiros, land, and genesis, birth) is upheavals or depressions of land exhibiting long wavelengths and little folding apart from broad undulations. The broad central parts of continents are called cratons, and are subject to epeirogeny. PLZ HELP ME FOR MATH!!! go to my profile and plz try answer my question, but if you dont get it plz dont answer!!!
Explanation:
The following is an example of an epeirogenic process is A large plateau forms in the interior of a continental plate when a large section of the plate rises evenly due to an even expansion of the underlying mantle.
The correct option is (C).
1. Epeirogenic processes involve broad-scale vertical movements of the Earth's crust, typically affecting large areas of continents rather than localized regions.
2. Unlike orogenic processes (which involve the formation of mountains through folding, faulting, and volcanic activity), epeirogenic processes result in more gradual changes in elevation over large regions.
3. The formation of large plateaus, such as the Colorado Plateau in the United States or the Deccan Plateau in India, is an example of epeirogenic uplift.
4. This uplift occurs when large sections of the continental crust rise evenly due to processes such as isostatic rebound or mantle convection.
5. Isostatic rebound refers to the adjustment of the Earth's crust in response to changes in surface loads, such as the melting of glaciers or the erosion of mountain ranges, leading to the uplift of previously depressed regions.
6. Mantle convection can also drive epeirogenic uplift by generating upward flow within the Earth's mantle, resulting in the buoyant uplift of continental crust.
7. Overall, epeirogenic processes contribute to the formation of large-scale topographic features such as plateaus, which play important roles in shaping the landscape and influencing regional climates and ecosystems.
complete question given below:
Which of the following is an example of an epeirogenic process? A. Mountains form along a convergent plate boundary when two plates collide, causing rock to bunch and buckle upward B. A rift valley forms at a divergent boundary where two plates are stretched apart. C. A large plateau forms in the interior of a continental plate when a large section of the plate rises eventy due to an even expansion of the undertyng mantle D. Mountains form along a convergent plate boundary when an oceanic plate slips beneath a continental plate, resuling in an upward force on the continental plate.

Which steps do geologists use to find the epicenter of an earthquake? Check all that apply.
They look at data from at least three seismographs.
They locate the point where circles intersect one another.
They measure the difference between arrival of P waves and S waves.
They draw circles around the epicenter from three locations.
They obtain information about the intensity of earthquakes from seismographs.
Answer:
They draw circles around the epicenter from three locations.
Explanation:
Geologists use triangulation method to determine the epicenter of an earthquake.
The epicenter of an earthquake is a point on the earth surface directly above the focus. The focus is the point beneath the surface where the earthquake occurs.
To determine the epicenter of an earthquake, we simply draw three circles whose point of intersection will be the epicenter. How do we now draw the circle?
From a seismogram obtained from 3 stations, we can deduce the time it takes a wave to travel. We simply compare the time lag between the first occurrence of the s-waves and that of the p-waves. Now that we have the time, we can determine the distance travelled by the wave. Since we know that the velocity of waves are constant, we simply use the relationship between velocity and time to find the unknown distance.
Using the distance as the radius, we draw three circles from different seismograph stations on a map. The point where the three circles intersects marks the epicenter of the earthquake.
Answer:
Option (1), (2), (3) and (4)
Explanation:
Earthquakes refers to the sudden shaking of the earth. It releases a certain amount of energy. During an earthquake, seismic P and S waves are generated that travels through the interior of the earth.
The seismographs that are located near the epicenter records the data during an earthquake. This data is then used to draw 3 circles around those 3 seismographs. The point where these 3 circles intersects is the location of the earthquake epicenter.
The arrival of P wave and S waves are also carefully observed. The P waves travels faster than the S waves, so they are recorded first in the seismograph. This difference between the arrival of these two waves are marked that is helpful for the determination of the epicenter.
The intensity of an earthquake is determined by the amount of damage it causes. It is measured by using a scale known as the Mercalli's intensity scale.
Hence, the correct answers are options (1), (2), (3) and (4).

what is chemotherapy
Chemotherapy is a process of intense treatment for cancer. It includes one or more anti-cancer drugs. However, most people become sick after they go through with chemotherapy. This can last for days or longer. Hopefully, nobody gets cancer and has to go through this procedure.
Chemotherapy refers to the use of chemicals or drugs to treat disease, often for cancer or to treat infections with antimicrobial drugs. It works by killing or inhibiting growth of target cells and is frequently used when other treatments are limited or not possible.
Explanation:Chemotherapy is a broad term that refers to the use of chemicals or drugs to treat disease. It is frequently associated with cancer treatments but can also refer to antimicrobial drugs that target infectious microorganisms. These drugs generally work by either killing target cells or inhibiting their growth, such as in the case of cancerous structures or infectious microbes.
The use of chemotherapy in cancer treatments involves drugs that interfere with the rapid cell division of cancerous cells. Such treatments are typically used when surgical removal of a tumor is not possible or when other traditional treatments like radiation or hormonal therapy have limitations. However, chemotherapy drugs often impact healthy tissue as well, leading to potential side effects such as nausea and hair loss.
In the case of antimicrobial chemotherapy drugs, they can be bacteriostatic (inhibit the growth of bacteria) or bactericidal (kill bacteria). The use of such drugs needs to be considered carefully to prevent superinfection and the development of antimicrobial resistance.

how does a pluripotent cell differ from a totipotent cell
Answer:
Pluripotent cells can be almost anything they want to be while totipotent are for ex, like zygotes. They can give rise to placenta and embryo
Answer:
Pluripotent cells, unlike totipotent ones, do not have the capacity to originate a complete living being.
Explanation:
Both pluripotent cells and totipotent cells are examples of stem cells.
Totipotent cells are those that have the capacity to transform into any cell type that can be found in the organism, which can give rise to a complete living being. are found in the embryonic zygote.
Pluripotent cells, on the other hand, do not have this same capacity, because they are not originated from extraembryonic tissues. Examples of these cells are the embryonic stem cells in the basticyst.

Read the paragraph. Then answer the question that follows. Perhaps you wanted pizza for dinner, but were out voted by the rest of the family who wanted chili. This is similar to what happens in a community. One person has to give up a right for the good of the group. Sometimes citizens' duties and rights conflict with each other. A good example is a public protest. People have the right to meet in groups and share ideas. However, a protest can disrupt traffic or other normal activities. A city must provide extra police protection to keep people safe. Therefore, the city has the right to require permission in advance for a protest. Government must make laws to balance the rights of individuals and different groups of people. Which of the following statements best describes this paragraph? The paragraph contains categories of comparison. The paragraph contains a simile. The paragraph contains no text connections. The paragraph contains an analogy.
Answer:the last one
Explanation:
Answer:
The paragraph contains an analogy.
Explanation:
Based on the above provided excerpt, we can see that the passage is an analogy on the two sides of every action. Just like the need to sacrifice the minority opinion for the majority, so is the same case for any protests or dissensions in a society.
Analogies provide comparisons between things for the better explanation of the issues concerned. By comparing the majority and minority opinions through the examples of "family pizza", " protests"or even "community rights", the author makes it a point to show the two sides of any story. Of course both opinions matter but for the sake of a democratized and equal footing of the two parties, there had to be some compromises made. And this is exactly what the analogy does. The analogy makes it perfectly understandable for the readers.

what minimum internal temperature must the salmon reach cooking
Answer:
145 degrees
Explanation:
Because the united states food and drug administration recommends cooking salmon to an internal temperature of 145 degrees Fahrenheit. Push the tip of the meat thermometer gently into the middle of the salmon fillet at its thickest part.
Salmon should be cooked to a minimum internal temperature of 145°F, as measured by a food thermometer, to ensure it is safe to consume.
When preparing salmon, it is essential for safety and health to ensure the fish is cooked to the appropriate internal temperature. According to the USDA and food safety guidelines, seafood, including salmon, should be cooked to a minimum internal temperature of 145°F. This temperature should be measured using a food thermometer to confirm that the salmon has reached the temperature sufficiently high enough to kill harmful bacteria that can cause foodborne illnesses. Additionally, it's important to make sure that when cooking fish in a microwave oven, there are no cold spots where bacteria can survive. For even microwave cooking, cover the seafood, stir, rotate, and if no turntable is present, manually rotate the dish once or twice during cooking.

Which feature is characteristic of healthy coral reefs?
A. Shallow, clear water
B. Clear freshwater
C. Deep, salty water
D. Cold, murky water
Answer:
Answer A
Explanation:
The correct answer is option A, that is, shallow and clear water. Coral reefs refer to the shallow-ocean habitats, which are occupied with sea life. The massive composition that coral reef comprises of is actually manufactured of coral polyps that are the small marine species, which live in colonies.
The hard compositions are left behind when these marine species die, and the branching and stony composition, which is left is limestone and is robust enough to produce a home for new species.
Healthy coral reefs are characterized by shallow, clear water and high biodiversity. The organisms living in the reefs have a mutualistic relationship with photosynthetic unicellular algae, which provide them with nutrition and energy. This clear water allows light to penetrate, supporting the growth of both corals and algae.
Explanation:Coral reefs are ocean ridges formed by marine invertebrates living in warm shallow waters within the photic zone of the ocean. They are mostly found within 30 degrees north and south of the equator. Coral reefs are characterized by high biodiversity and the structures created by the invertebrates that live in them. They provide nourishment and shelter for a wide variety of species, including over 4,000 fish species.
Shallow, clear water is characteristic of healthy coral reefs. The organisms living in these reefs have a mutualistic relationship with photosynthetic unicellular algae, which provide them with nutrition and energy. The clear water allows light to penetrate, allowing the algae to carry out photosynthesis and the corals to thrive.

they will be able to combine between themselve
Answer:
B. There are only 20 amino acids and 64 possible combinations
Explanation:
The genetic code is degenerate this means that more than one codon codes for a single type of amino acid.This degeneracy occurs because there are 64 possible triplets of the bases that exist however there are only 20 amino acids known to encoded by the genetic code. Out of this 64 possible triplet codons, 61 triplets are responsible for coding the amino acid whereas three of them form a stop codon that helps terminate the translation.1.

The two options that could potentially be considered 'benefits' of climate change are increased demand for building construction due to adaptation needs and increased crop growth in some regions due to warmer temperatures.
Explanation:While climate change is generally viewed as a global problem with significant negative impacts, there are indeed a few potential 'benefits' that might occur. However, it is important to note that these potential benefits are often far outweighed by the potential harm.
In terms of your options, the two that could be considered potential benefits of climate change are:
B. Increased demand for building construction and E. Increased crop growth.
As sea levels rise and temperatures change, there may be an increased demand for building construction to adapt to these changes. This could also stimulate economic activity.
Warmer temperatures can also lead to longer growing seasons in some regions, potentially increasing crop growth. However, this is a complex issue and the overall impact on agriculture is likely to be negative due to factors such as increased drought and unpredictable weather patterns.

Match the terms to their definition. 1. chromosome a cell whose nucleus is not bound by a membrane 2. eukaryote a genetic characteristic of an individual 3. gene a specific sequence of DNA nucleotides that carry hereditary traits 4. prokaryote a cell that has a membrane-bound nucleus 5. trait tight coils of DNA
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
Correct matches: 1-Chromosome to tight coils of DNA, 2-Eukaryote to a cell with a membrane-bound nucleus, 3-Gene to sequence carrying hereditary traits, 4-Prokaryote to a cell without a membrane-bound nucleus, and 5-Trait to a genetic characteristic.
The terms and their correct definitions would be matched as follows:
Chromosome - tight coils of DNAEukaryote - a cell that has a membrane-bound nucleusGene - a specific sequence of DNA nucleotides that carry hereditary traitsProkaryote - a cell whose nucleus is not bound by a membraneTrait - a genetic characteristic of an individualChromosomes are structures that contain genes, which determine specific traits in an organism. Eukaryotes are organisms whose cells have a membrane-bound nucleus which houses these chromosomes, while prokaryotes lack such a nucleus, often having DNA concentrated in a nucleoid.
How can one tell if a reaction has reached equilibrium?
O
A. The reaction starts to go in the reverse direction.
B. The concentrations of products and reactants stop changing.
O
C. The concentrations of products and reactants are equal.
O
D. The reaction stops once the reactants have been used up.
A chemical reaction reaches equilibrium when the concentrations of products and reactants stop changing, which corresponds to the forward and reverse reactions occurring at equal rates, making the system's reaction quotient (Qc) constant. This is known as dynamic equilibrium.
Explanation:To determine if a reaction has reached equilibrium, one looks for a state where the concentrations of products and reactants stop changing. Despite the absence of visible changes in concentrations, both the forward and reverse reactions are still occurring at equal rates. This does not imply that the amounts of reactants and products are equal, but that they are constant due to the equal rates of the forward and reverse reactions represented by a double-headed arrow, as in A+B=C+D. During the approach to equilibrium, you'll observe that the reaction quotient (Qc) changes as product and reactant concentrations change; once equilibrium is reached, Qc remains constant.
Dynamic equilibrium is a term used to describe this state. It may seem as if the reaction has stopped, but in reality, the system is dynamically balanced with the forward rate of forming products (C & D) being equal to the rate of the reverse reaction of these products turning back into reactants (A & B).

What causes the bonds to break in a chemical reaction
Answer:
Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds and energy is also released when bonds form. ... In an exothermic reaction, the products have (more or less) energy than the reactants.
Explanation:
Final answer:
In a chemical reaction, bonds in the reactants are broken and new bonds are formed in the products. Energy is required to break the bonds and is released when the bonds are formed. This rearrangement of atoms forms new substances.
Explanation:
A chemical reaction involves breaking bonds in the reactants and forming new ones in the products. When a chemical bond is broken, energy is required, and when a chemical bond is formed, energy is released. The amount of energy needed to break a bond is the same amount of energy released when the bond is formed.
For example, in the reaction 2H₂O → 2H₂ + O2, the bonds of two water molecules (H₂O) are broken to form hydrogen (H₂) and oxygen (O2).
Overall, a chemical reaction involves the rearrangement of atoms and the breaking and forming of chemical bonds, which results in the creation of new substances with different compositions.
