Answer:
Main Concept Seismology is the study of earthquakes, their effects, and seismic waves.
Explanation:
The earthquake epicenter is a point on the Earth's surface directly above an earthquake. Scientists determine the epicenter by studying the P waves and S waves produced by all earthquakes. P waves are compression waves and travel faster through the Earth than S waves.

Redshift
Blueshift
Neither of these
Answer:
The correct answer is "Red shift"
Explanation:
Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.
Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.

Answer:
22. C
23. C
24. Not clear, maybe 18%
25. Left ventricle, because according to the graph nearly 50% of the organ contains mitochondria, more than the left atrium.
Explanation:
22. Active transport requires cell's energy to move molecules, usually in the form of ATP.
23. This is a trick question, you might think it is diffusion or osmosis, but is is exocytosis. Diffusion and osmosis don't require vesicles for transport. It isn't endocytosis, because that is moving molecules inside the cell. The question asks for moving out the cell.
24. Look at the chart, it is less than 20, but more than 10 and more than halfway. I am not sure exactly the percentage, I would approximate it to be 18%.
25. Most likely left ventricle.

Identify the phases in the life cycle of small and big stars. supernova: In this stage, the star collapses and produces elements heavier than iron. planetary nebula: In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core. neutron star: In this stage, the star has reduced to an extremely dense core. white dwarf: In this stage, the star has reduced to a dense core.
Explanation:
Some Astronomers believe the life cycle of small stars begins in this order:
Planetary nebula phase: this phase is the result of the previous red giant phase (when the star turns red in color). However, at this stage, the star keeps expanding, glowing, and getting hotter as it strives to complete its life--cycle.White dwarf phase: As the name implies, the star now has a reduced size and a dense core than during the Nebula phase, while still glowing with surface temperatures of over 100,000°C.Neutron star: This stage occurs next after the White dwarf phase which may result in the final death of the star. Here the star is reduced to an extremely dense core.While the life cycle of big stars begins in the order:
Supernova phase: At this phase, the star collapses and produces other heavier elements.Neutron star phase or may formBlack Holes.The image shows gannets (a type of shorebird) on their nesting grounds. If

Why does humus tend to increase with the clay content of soil?
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
B.
As the clay content increases, the amount of plant lignin in the soil increases.
C.
As the clay content increases, the permeability decreases, which increases the rate of decomposition.
D.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which increases the rate of decomposition.
Answer:
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
Explanation:
This is true because, humus which is the dark rich matter made up of organic matter would be able to be adsorb into the clay content of the soil due to the size of the particles component. The surface area in the soil is a strong factor when compared with other soil type with smaller surface area.
process by which earths life form change over time
Answer:
Adaptations develop from variations within a population and help organisms to survive in their given environment. Changes in populations accumulate over time; this is called evolution. The fossil record shows us that present-day life forms evolved from earlier different life forms.
Which of these organisms would most likely be found at the top of an energy pyramid?
A. clams - a primary consumer
B. sardines - a primary consumer
C. sharks - a secondary consumer
D. kelp - a primary producer
Answer:
sharks
Explanation:
Because they are the ones to get the last bit of energy. Secondary consumers are the group in the food chain that eats primary consumers. This means that secondary consumers can either be omnivores or carnivores. These terms refer to whether or not they eat just meat or a varied diet. Secondary consumers don't need to have a specific diet.
The energy pyramid is a representation of the producers and consumers along with the flow of energy. The sharks will be at the top of the energy pyramid. Thus, option C is correct.
What is an energy pyramid?An energy pyramid is a graphical representation of the biomass of the producers and the consumers of the ecosystem. It consists of the trophic levels that have designated producers, primary consumers, and secondary consumers.
A producer is at the bottom of any energy pyramid as they produce the foods for the primary consumers that are most likely herbivores. The secondary or the tertiary consumers are at the top.
Therefore, option C. sharks being secondary consumers are at the top of the pyramid.

How are catastrophic events related to changes in geological timelines?
A. They aren't related to changes in the geological timeline because they don't change the
overall population dynamics.
B. They aren't related to changes in the geological timeline because the timeline is dictated
by temperature cycles.
C. They cause significant changes that disrupt the equilibrium of the earth and lead to
natural separation points.
D. They define geological periods because scientists use them as reference points for
tracking the history of the earth.
PLEASE ONLY ANSWER IF YOU KNOW-
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
i) Predict which of the liquids would cause the largest decrease in mass of a potato stick
PLS HELP ME I’ll GIVE YOU 15 POINTS OR BRAINIEST
Answer:
1.0 mole per dm3 sodium chloride solution
Explanation:
The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.
Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.
The resting membrane potential of a neuron is generated by Group of answer choices the selectivity of the membrane to pass positive charges only. the greater mobility of small ions. diffusion of ions as a result of their concentration gradients. All of them repulsion of positive and negative charges.
Answer: diffusion of ions as a result of their concentration gradients.
Explanation:
Resting membrane potential can be defined as the basic charge of the cell. It is defined by the concentration difference between the ions due to the action of the ion pumps. The differential permeability of the membrane is because of the charge on the ions and leads to the creation of the ion channels. The negative charged ions accumulate on the inner side of the cell.

If you were to test a small
sample of soda lime with
universal indicator would it
register a pH above or
below 7? Explain your answer
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.
