C. It speeds up a chemical reaction, without being consumed in the process.

D
It slows down a chemical reaction, but is consumed in the process.

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.

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.

I believe the answer is C) How does a change in temperature affect the reproduction of crayfish?

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.

Answer:

Ionic and covalent bonds are intramolecular bonds and Hydrogen bonds are intermolecular bonds

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.

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.

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.

Answer: dependant variabkle

Explanation:

The option C (diffusion) is correct option.

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.

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.

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.

The option D is correct option.

The option B is correct.

The salt solution compared to blood 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.

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.

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.

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.

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.

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.

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.

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.

An asteroid refers to an eosinophilic body exhibiting gradiating lines, observed in a vacuolated region of the cytoplasm of a multinucleated giant cell, mainly witnessed in sarcoidosis, however, also observed in other granulomas.  

It is also considered as a structural feature of sporotrichosis when observed in the skin or in secondary lesions of sporotrichosis. Thus, in order to be considered as a cell, it must possess a nucleus and membrane-bound organelles.  

Asteroids, such as C-type asteroids, contain components like organic carbon compounds and bound water, which are vital to life. However, to be considered a cell, it must have a cell membrane, genetic material, metabolism, and the capability to reproduce. There is no evidence yet of complete cells within asteroids.

Asteroids, especially C-type asteroids, are known to contain organic carbon compounds, silicates and chemically bound water, all of which are vital to the formation of cells. As remnants from the early solar system, asteroids may hold clues to the building blocks of life.

However, for a material to be considered a cell, it must meet several criteria. It must have a membrane that separates it from its surroundings, it must have a genetic material (DNA or RNA) for information replication, it must exhibit metabolic processes to utilize energy, and must be able to reproduce or self-replicate. Given the existing knowledge, asteroids do not contain fully formed cells, but they do hold some of the chemical precursors needed for life.
