Explanation:

A rock that formed more than 10,000 years ago

Answer:

Different grain sizes of sediments are important to form different types of rocks. Geologist have great interest in studying sediments and their grain size.

Farm with black loam will be the best for growing crops. So, the correct option is D.

Loamy soil is defined as a soil that is composed mostly of sand, silt and a small amount of clay. By weight, its mineralogical composition is approximately 40–40–20% concentration of sand–silt–clay, respectively.

Loam describes a specific type of soil that has been prepared from a mixture of sand, silt, and clay, while sandy loam soil is a very desirable medium used by farmers, gardeners, landowners, and property owners because It has very beneficial properties.

This soil is good for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots

Thus, farm with black loam will be the best for growing crops. So, the correct option is D.

Evidence of low rainfall in a specific year can be identified through decreased agricultural outputs, thin tree rings indicating stressful growing conditions, and historical climate events associated with dry conditions such as the Little Ice Age.

Evidence of a year with low rainfall can be seen in several aspects of our environment. Some of the clearest indicators may be observed in agricultural output, tree ring records and historical climate events.

First, significant droughts can impact agricultural production sharply. For instance, in 2014, the Manchuria Plain in China experienced its intense drought in 50 years, resulting in a dramatic decrease in wheat, corn, and soybeans supplies. Thus, in years with low rainfall, we may expect to see a decline in the amount of agricultural products supplied at any given price.

Secondly, nature provides its own historical record through annual tree rings. These rings can reveal prevailing climatic conditions during each growing season. A thin ring usually suggests low rainfall or high temperature stress which impaired growth.

Lastly, major historical climate events, like the Little Ice Age in Europe in the fourteenth century is characterized by cold weather and, in some areas, droughts which reduced available food supplies due to low rainfall.

Answer:  circulate and move within a liquid or gas

Explanation:

hope it helped xx

In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

Convection currents arise by the difference in particle density in the fluid. Generally, warmer particles are less dense and tend to rise, while colder particles are denser and tend to do the opposite motion.

For convection to occur, a propagating medium, usually fluid (liquid or gaseous), must exist, because convection cannot move through empty spaces. This process of heat propagation happens due to the emergence of convection currents in the fluids.

This happens, for example, when heating water in the stove. The deeper molecules near the fire heat up faster, becoming less dense than the molecules closer to the surface.

All bodies emit energy by radiation at all times. At temperatures close to the environment, this phenomenon can usually not be perceived by human eyes, but can be seen when the body is at very high temperatures, such as a glowing ember.

Therefore, In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

An organism's habitat is its physical environment, like the grasslands for prairie dogs, while an organism's niche is its specific role within the ecosystem. Prairie dogs' niche includes burrowing and serving as prey, which is critical for many other species' survival, making them a keystone species. Without prairie dogs, the ecosystem might face collapse.

An organism's habitat is its physical environment. For prairie dogs, this would be the grasslands or prairies where they live. In contrast, an organism's niche refers to its specific role within the ecosystem. Prairie dogs, as a species, have a niche that includes their extensive burrowing activities and their role as a primary food source for predators.

Prairie dogs are a keystone species because their burrows provide critical shelter for many small animals and their existence as prey supports numerous predators. By creating and maintaining burrow systems, they also help to aerate the soil, which benefits plant growth, and their foraging behavior can influence the distribution of plant species.

Without prairie dogs, their ecosystem could potentially collapse due to the loss of these critical functions. For example, the burrows they dig offer protection and habitats for other species, which contributes to the overall biodiversity of the ecosystem. If prairie dogs were to disappear, the ripple effects would be profound, impacting both predators and other small animals reliant on the burrows for shelter.

Explanation:

Final answer:

ATP, known as the energy currency of the cell, transfers energy to cell processes and releases that energy upon breaking the bond between its second and third phosphate groups. The correct option is b.

Explanation:

The correct statement about Adenosine triphosphate (ATP) is that it transfers energy to cell processes. ATP is often referred to as the energy currency of the cell, as it stores the energy derived from the catabolism of nutrients, like glucose and fats, and releases it to power various cellular functions. ATP consists of an adenosine molecule attached to three phosphate groups; when it is used for energy, the bond between the second and third phosphate groups is broken, resulting in the formation of ADP (Adenosine diphosphate) and a release of energy. This process is known as phosphorylation, where the third phosphate group is temporarily attached to another molecule, often to activate or deactivate it or to enable it to participate in a subsequent reaction. Hence, Option b is accurate.

The characteristics of life that best explains people having a stable internal body temperature is homeostasis. The correct option is C.

Homeostasis is the state of constant internal, physical, and chemical conditions maintained by living systems in biology.

This is the state of the organism's optimal functioning, and it encompasses many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.

The tendency to resist change in order to maintain a stable, relatively constant internal environment is referred to as homeostasis.

Negative feedback loops are commonly used in homeostasis to counteract changes in various properties from their predicted values, known as set points.

Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions.

Thus, the correct option is C.

Hello. This question is incomplete. The complete question is:

"Which of the following best describes the long-term impact of using a nonrenewable energy source?

A: Geothermal energy can disrupt the water table and harm water supplies.  B: Nuclear power damages the atmosphere by producing air pollution.  C: Burning biomass to produce energy releases greenhouse gases.  D: Coal mining can pollute water supplies and kill fish and aquatic plants."

Answer:

D: Coal mining can pollute water supplies and kill fish and aquatic plants.

Explanation:

The use of non-renewable energy has proven to be a strong pollutant of ecosystems and biomes. Coal mining is an example of how the use of non-renewable energy degrades nature.

The environmental impacts of mining are diverse and varying in scale: from specific local problems to major biological, geomorphological, water and atmospheric changes. Therefore, knowing these problems and minimizing their effects is of great necessity to ensure the preservation of natural environments.

Coal mining can pollute the water supply and kill fish and aquatic plants. Not to mention the degradation of soil and vegetation that this activity promotes.

Final answer:

The dew point is the temperature at which air reaches 100% relative humidity and water vapor condenses into liquid water. To find the dew point, we can use the relative humidity and the temperature. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point using these values.

Explanation:

The dew point is the temperature at which air reaches 100% relative humidity. It is the point at which water vapor in the air begins to condense into liquid water. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point by multiplying the relative humidity by the saturation vapor density and converting it to a temperature.
