Under the surface of the Earth, the graphic depicts magma and rock strata, metamorphic rocks most likely to form 3rd layer.

The ideal answer is C.

the frozen magma layer Igneous rock, a subclass of rock, is formed by stone. Extrusive igneous rocks are created by magma that freezes after it has reached the earth's surface. While the earth's frozen magma, which has not yet reached the surface, creates an intrusive rock type. Igneous rocks, on the other hand, refer to all rocks created by the freezing of magma.

Magma was present before the occurrence ever began. The foundation of all rock formation is this magma. Due to the presence of magma that was crystallizing beforehand, the formation of rocks was the first.

If you push down an effort distance of 1.5m using an effort force of 60N, the box will rise distance of 0.9m.

To lift a 100N box onto a shelf. If we push an effort distance of 1.5m using an effort of 60N. The 100N box will rise up by a distance H.

This distance d can be calculated,

Using law of conservation of energy,

As there is no external force on the body the concept of conservation of energy can be used here,

It means that the applied energy will be equal to the output energy in the ideal conditions.

So, we can write,

Energy(applied) = Energy(Output)

mgh = MgH

Where,

mg is the effort force of 60N,

Mg weight of the box to be lift which is 100N,

h is the effort distance of 1.5 meters and,

H is height by which the box will rise.

Putting all the values,

The hypothesis that supports that micelles are held together by non-covalent interactions are: (B) The number of micelles increases, and the size of the micelles decreases.

Non-covalent interactions are the bonds that are formed without the sharing of electrons. The example of the same are: ionic bonds, hydrophobic interactions, hydrogen bonds and Van der Waals forces.

Micelles are the spherical structures formed by lipids in aqueous solution. The hydrophobic tail of the micelles remains on the inside while the hydrophilic head remains on the outside. Since the micelles are held together by non-covalent interaction, they can break off easily upon constant agitation. This is why the micelle size decreases. Since it is the tendency of lipids to form micelles in aqueous solution, the separated lipids due to agitation will again join together to form another micelle, hence their number increases.

Explanation: answer from biology class hope it helps

The correct option is first, as the jackrabbit's circulatory system increases blood flow to the ears during hot days and blood flow to the ears decreases during cool or cold nights.

Homeostasis is vital to preserving an ideal environment for cell structures to work effectively. The direction of a cell or an animal's inner environment in reaction to changes within the outside environment is called homeostasis.  

In this case, the jackrabbit's circulatory framework is reacting to fluctuating temperatures.

On hot days, the body is at a chance of warming up over ideal temperature which might obstruct body capacities. In this manner, the bloodstream to the ears is expanded to encourage heat loss.

In cold temperatures, the bloodstream to the ears is diminished to moderate warm for crucial body organs. The bloodstream is coordinated to the center of the body to secure the heart, lungs, liver, and brain.

The most likely cause of the pollutant on Kendis if he keeps eating the predator fish is that Kendis will get sick because the pollutants will biomagnify (option C).

Biomagnification is the process, in an ecosystem, in which a higher concentration of a substance in an organism is obtained higher up the food chain.

According to this question, Kendis eats predator fish that feed on small oysters in a river ecosystem. However, the river has become polluted with moderate levels of heavy metals which are absorbed by the oysters.

This means that a continuous consumption of the predator fish will lead to a bioaccumulation of the heavy metals in Kendis causing the metal concentration to biomagnify.

Therefore, Kendis will likely get sick due to the bioaccumulation of the metal.

Answer: B the weight of the cattle compacts the soil

Explanation:

ecosystem related would mean that the answer relates to the land. this rules out A and D as they are related to profits off of the land and not necessarily the health/wellbeing of the physical land. C is also out-ruled as the price of the cattle is not a directly going to negatively effect the land.

The weight for the cattle is very relevant as cattle are very heavy and with regular walking/grazing/standing on the rangeland the soil will become harder (aka. compact) resulting in less loose soil for grass to grow.

This can be off set by allowing the land to rest or other means such as plowing occasionally so that it is easier for grass to continue to thrive for feeding the cattle.

After Johanna pushes it for a while, she begins to feel tired. Here Thermal energy is being transformed into the kinetic energy that she is using.

The energy that an object has as a result of its ongoing motion is known as kinetic energy in terms of physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The body holds onto the kinetic energy that it acquires during this acceleration until and unless its speed changes. Kinetic energy has the following formula: K.E. = ½ m v2, where m is the object’s mass and v are its square velocity.

The kinetic energy that is measured in kilograms-meters then squared per second squared if this mass is then measured in kilograms and the velocity is then measured in meters per second.

When potential energy is released, among other catalysts such as elastic forces or gravity, kinetic energy is produced.

Explanation:

This is an example of Positive feedback

In contrast to negative feedback, positive feedback occurs when an output is used as a signal to increase further response of the output. In other words, if process A results in consequence E, E reinforces process A, resulting in a cascade where more of E occurs, which causes more of A to occur, and so on.

That is to say, E signals to A to continue the sequence of reactions leading to output E in itself. In most cases, positive feedback always acts to elicit a response from the initiating or preceding steps in a pathway. It is called positive feedback because the result of the action is to amplify the output of a process.

The lichens are especially sensitive to air pollution.

The Air Quality Index (AQI) is used for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air.

Urban air quality refers to how “clean” the ambient air is inside of cities with a density, population, and level of activity that generally are recognized as “urban.” Urban air quality generally differs from rural air quality since there are more concentrated sources and the ability for the pollutants in the air to be dispersed are limited by the physical constraints of the urban environment. Urban air quality varies significantly in urban cities in industrialized worlds, and non industrialized world generally because of the difference between control on pollution sources and use of open fires in the urban areas. Nevertheless, illness, deaths, and damage to the environment are still attributed across the world to air pollution.

To grow, lichens obtain their nutrients from the air.

Since lichens have neither roots nor a protective surface, they cannot filter what they take in, so they take in whatever is in the air directly. Pollutants can accumulate in the lichen and become toxic very quickly.

Museum lichen researcher Gothamie Weerakoon believes lichens are excellent indicators of air pollution. She says, "They are very sensitive, respond to pollution within a short period of time, and we have access to very good databases that allow us to understand different species of lichens.
