What two pieces of information are needed to determine ocean depth through echo sounding?
Sonar is an instrument which is used to search for things which are underwater. It is also used to find the depth of water by giving out ultrasonic vibrations into the water. The time which the vibrations take to return assists to find the distance of the reflecting surface.
The correct answer is:
• velocity of the wave and
• the return time of the wave.
Echo sound is the method for determination the water depth, based on transmitting sound waves into water. Two things that are recorded are the time interval between emission and return of a pulse and the speed of sound in water at the time.
compare and contrast geology and etymology
Geology is the study of the rocks and similar substances that make up the earth's surface, it is also considered as the study of the rocks and physical processes of the Earth in order to understand its origin and history. On the other hand, Etymology the study of the origin and history of words, or a study of this type relating to one particular word and how their form and meaning have changed over time.
Answer:
Geology refers to the branch of science, which studies the composition of the Earth or other planets, together with its development and origin. It is generally done by performing an examination of the rocks. On the other hand, etymology refers to the study of the historical development of languages, mainly as demonstrated in individual words.
What list describes the diet of an omnivore? Mice and rabbits Rabbits and insects Fish and insects Fish and berries
The correct answer is D. Fish and berries.
Explanation
Omnivorous is a term of Latin origin that means eating everything. At present, the term is used to refer to all species of animals (including humans) that eat different foods, that is, omnivorous animals, unlike carnivores (which feed exclusively on meat) and herbivores (which it feeds exclusively on plants) eat herbs, fruits and meat. Therefore, it can be affirmed that the diet of an omnivore is composed of fish and berries. So, the correct answer is D. Fish and berries.

a decrease in pressure
hope this helps :)
Answer:
a decrease in pressure
Explanation:
A Divergent Limit occurs with the tectonic plates moving away in opposite directions and directions, so there is addition of magmatic material to the Earth's crust at this point. Magma ascends through a space that exists between the plates, called Rifte. At the divergent boundaries of the plates in the ocean, magma rises and melts because of a decrease in pressure caused by the removal of these plates.

The option C (diffusion) is correct option.
According to condition NaCl concentration is more outside the cell than inside the cell.So it will diffuse through cell membrane, from high concentration to low concentration.Part 2.The option C is correct which is into the cell.
As the concentration both ions is more outside the cell so they will diffuse through cell membrane, from high concentration to low concentration.
Part 3.The option B is correct which is occur into the cell.
According to condition NaCl concentration is more outside the cell than inside the cell.
So the net diffusion occurs into the cell.
Part 4.The option D is correct option.
The diffusion of water will be in both direction. First it will be outside the cell, then inside the cell.
Part 5.The option D is correct option.
Osmosis the movement of water from its high concentration to low concentration.So concentration of water is low outside the cell. Hence osmosis will be outside the cell.Part 6.The option B is correct.
The salt solution compared to blood will be hypertonic.
A hypertonic solution is a particular type of solution that has a greater concentration of solutes.Since blood has low salt than solution so solution will be hypertonic.Correct option: C ( Diffusion).
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.
NaCl concentration is more outside the cell than inside the cell. So it will diffuse through cell membrane, from high concentration to low concentration.
Part B.Correct option: C ( into the cell).
Ions ( Na+, Cl-) are more outside the cell than inside so they will move through cell membrane, from high concentration to low concentration, outside to inside the cell.
Part C.Correct option: B (occur into the cell).
As NaCl concentration is more outside the cell than inside the cell.
Net diffusion = Diffusion into the cell + Diffusion outside the cell
So the net diffusion occurs into the cell.
Part D.Correct option: D (occur in both directions)
Diffusion of water will be in both direction depending on the concentration of solutes, inside and outside the cell. First water will diffuse outside then inside the cell.
Part E.Correct option: D (occur outside the cell).
Under these conditions, NaCl concentration is more outside the cell than inside the cell. So water will move oppositely from inside to outside the cell.
Part F.Correct option: B (hypertonic).
A hypertonic solution is a particular type of solution that has a greater concentration of solutes.
Hence salt solution compared to blood will be hypertonic. because it has more salts concentration than blood.

Eukaryotic cells are much larger and have more specialized functions than prokaryotic cells because they contain___________, which take up space and carry out specialized activities.
Final answer:
Eukaryotic cells contain organelles that are essential for various specialized functions, unlike prokaryotic cells which lack these structures.
Explanation:
Eukaryotic cells are much larger and have more specialized functions than prokaryotic cells because they contain organelles, which take up space and carry out specialized activities. While prokaryotic cells lack these membrane-bound structures, eukaryotic cells boast an assortment of organelles such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus among others. Each of these organelles plays a critical role in the cell's life, with functions ranging from genetic material storage and energy production to protein synthesis and waste processing.

The map shows the distribution of wild boars in the United States. Wild boars are an invasive species to the United States. Which of these facts about wild boars is best supported by the evidence provided? Wild boars were brought to the United States by humans. Wild boars have quickly spread through the United States. Wild boars have established successfully in areas with warm climates. Wild boars have a high reproductive rate and no natural predators.
I'm pretty sure it's D, I could be wrong but it seems like it's the most correct answer.
Answer:
Option D,
Explanation:
It is given that wild boars are invasive species which means they are not native to the ecosytems of united states and since they are invasive they are also harming the native plants and animals life.
An invasive species becomes disastrous because there in no known way of controlling it.
Wild boars being invasive spread to different locations of USA , thus they must be having a high reproduction rate . Also, they , they might not be having any natural predators , therefore they have grown uncontrollably
Hence, option D is correct

6. A mass extinction occurs after several volcanic eruptions; Natural causes.
The changes in biodiversity can be influenced both, by the humans and their activity, and the natural events that are taking place on our planet. Throughout the geologic history, lots of natural events. like asteroid collisions, super-volcano eruptions, changes in the composition of the atmosphere etc, have resulted in the dying out of millions of species, and even though this process of natural selection continues, it is not the dominant cause anymore. Nowadays, the biggest cause of loss and changes of biodiversity is the human activity. Lots of living organism have lost their habitats and food sources and went extinct because of the human activity, and also some species have died out or are on the verge of extinction because of the introduction of non-native species to certain places, and that has been devastating to the local wildlife.

Which of the Milankovitch cycles changes the shape of the earth's orbit around the sun? A) eccentricity B) axial tilt C) precession D) rotation
Eccentricity.
Good luck!!
The answer you are looking for is A) Eccentricity
the path of the Earth's orbit around the sun is not a perfect circle, but an ellipse. This elliptical shape changes from less elliptical (nearly a perfect circle) to more elliptical and back, and is due to the gravitational fields of neighboring planets (particularly the large ones – Jupiter and Saturn).

1. The fossil shown in this photo is of a Basilosaurus. Its skeletal features suggest that it spent its entire life swimming in the ocean. Look at the environment the fossil was found in. Consider that Basilosaurus lived in the ocean. How has the environment of this location changed since Basilosaurus lived?
Answer:
The environment changed drastically probably due to tectonic plates shifting and either causing this part of land to move to a higher altitude or blocking the water from being in this now deserted place. At some point it seemed to be a river shown in the picture of the rock on the top right corner, as the rock looks a bit corroded it seems that the ocean slowly disappeared.
Explanation:
i had to do this to soo hope this helps
Final answer:
The environment of the location where the Basilosaurus fossil was found has changed over time. Geological processes and shifts in physical and chemical conditions have influenced the types of organisms that can thrive there.
Explanation:
The environment of the location where the Basilosaurus fossil was found has changed since Basilosaurus lived. Basilosaurus was an ocean-dwelling creature, and it is likely that the environment was once a large body of water. However, over time, geological processes such as tectonic movements and changes in sea level could have caused the area to undergo significant transformations. For example, the location of the fossil may now be on land or part of a different marine environment.
These changes in the environment could be reflected in the surrounding rock formations and the types of fossils found in the area. Fossils of other marine creatures, such as Mesosaurus, Lystrosaurus, and Cynognathus, indicate that different organisms inhabited the area at different times in the past. This suggests that the environment has gone through various shifts and adaptations over millions of years.
Overall, the environment of the location where the Basilosaurus fossil was found has likely experienced changes in physical and chemical conditions, which have influenced the types of organisms that can thrive there.
The behavior expected of someone occupying a particular status.
the answer is role (:
The expected behavior of someone occupying a particular status is referred to as a role in sociology. The roles, which are actions and reactions predicted by societal context, are linked to the social status. Each status can hold a variety of roles and these roles depend on the societal and cultural context.
Explanation:The expected behavior of someone occupying a particular status relates to the concept of social roles in sociology. These behaviors are often referred to as roles, which are expected actions and reactions based on societal context. Roles are connected to social statuses; both ascribed (those you do not select, such as son or daughter) and achieved (those you choose, such as a nurse or a self-made millionaire).
For example, the status of 'student' has a set of cultural and societal expectations attached to it - attending classes, doing homework, obtaining grades, interacting with peers and teachers in certain ways - these make up the 'role' of the student associated with that status.
Each status a person holds comes with a certain role-set, also known as a range of roles attached to a particular status. This expectation to fulfill certain roles in society is part of the socialization process and varies with societal context and culture.

A scientist uses material in her lab to separate dna fragments by size what process is she using
She is using gel electrophoresis, where a DNA sample with DNA molecules of varying length are ran through an agarose gel to separate them into bands by size from longest at the top to shortest at the bottom.
Answer: Gel electrophoresis
Explanation:
Gel electrophoresis is a technique that is used to separate DNA fragments based on their size.In this technique, DNA samples are loaded into the wells at one end of a gel, and then an electric current is applied. DNA fragments being negatively charged move towards the positive electrode. Since, all DNA fragments have the same amount of charge per mass, small fragments move through the gel at a faster rate than large ones.In this way the fragments get separated by size.Which of the following can be used to induce abortion nonsurgically?

how are ionic and covalent bonds different from hydrogen bonds?
Ionic and covalent bonds are intramolecular bonds, meaning that they exist inside the molecule. These bonds deal with the exchange of electrons.
Hydrogen bonds are intermolecular bonds, meaning they bond two separate molecules. These bonds deal with the attraction between hydrogen and electronegative elements such as O and F.
Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. Other types of bonds include metallic bonds and hydrogen bonding.
Ionic vs covalent
Ionic bonds form between a metal and a non-metal. In these bonds, the electrons from the metal are donated to the non-metal.
Covalent bonds form between two non-metals. In these bonds, electrons are shared between the two atoms.

She can make an OxiClean commercial.
Kyle does an experiment to test the effectiveness of a new type of fertilizer. He predicts that the fertilizer will make plants grow twice as fast as they would without the fertilizer. After the experiment is complete, Kyle's collected data show that the fertilizer only worked 60% of the time. Kyle decides to remove the data that contradicts his prediction from his published results so that his published conclusion will show that the fertilizer is 100% effective. The published results of Kyle's experiment
Answer:
The published results of Kyle's experiment are false and unethical
Explanation:
Kyle wanted to find the effectiveness of the new fertiliser. He believed that it would make the plants grow twice as fast as they would without fertiliser but this result was achieved only 60% of time.
Kyle should have reported this original result without altering it. This would have led people to work on the fertiliser more and improve its quality. Some agriculturists might have even looked for other better fertilisers to improve their crop production. But based on Kyle's false results all these people can be misguided to believe that the test fertiliser is 100% effective hence what Kyle did was totally unethical.
Final answer:
Kyle's modification of his experiment's data to only include supportive results undermines the scientific validity and integrity of his study on fertilizer effectiveness.
Explanation:
Kyle's decision to remove data contradicting his hypothesis from the published results of his fertilizer experiment compromises the scientific integrity of his study. Conducting a scientifically valid experiment involves not only developing a hypothesis and collecting data but also accurately presenting all results, regardless of whether they support the initial prediction.
Removing or altering data to fit a desired outcome is unethical and can lead to misleading conclusions about the effectiveness of the fertilizer. In science, it is crucial to report findings truthfully to advance knowledge and understanding accurately.
