1) 95% of the crop is derived from the soil during the growth process. The soil provides essential nutrients such as nitrogen, phosphorus, and potassium that are necessary for plant growth. These nutrients are absorbed by the plant roots and used to produce energy and support various physiological processes.
2) The remaining 5% of the crop's nutrients can come from other sources such as air, water, or fertilizers. For example, plants can absorb carbon dioxide from the air and convert it into carbohydrates through photosynthesis.
3) A lack of nutrient availability is typically a function of two aspects: soil nutrient content and soil pH. The nutrient content refers to the amount of essential nutrients present in the soil, while soil pH affects the availability of these nutrients.
4) Mulder's Chart, also known as the nutrient mobility chart, is used to determine the mobility of different nutrients in the soil. It helps farmers and agronomists understand which nutrients are more likely to leach or move with water in the soil profile and which are more likely to stay in place.
5) Soil temperature is important in the nutrient and plant relationship because it influences the biological and chemical processes that affect nutrient availability and plant uptake.
6) Immobilization refers to the process in which nutrients in the soil become temporarily unavailable to plants. This occurs when soil microorganisms use the available nutrients as a source of energy and growth.
7) From the Four Bases of Healthy (Mineralized) Soil section, the two nutrients considered to be "foundational elements" are nitrogen and phosphorus.
8) Of the three major nutrients, nitrogen and potassium are typically used in the largest amounts by plants. Nitrogen is essential for vegetative growth, while potassium plays a vital role in plant development, nutrient uptake, and water regulation.
9) A cation has a positive charge. In soil chemistry, cations are positively charged ions such as calcium (Ca2+), magnesium (Mg2+), and potassium (K+). These cations are attracted to negatively charged soil particles and are vital for plant nutrient uptake.
10) Liebig's Law of the Minimum states that plant growth is limited by the nutrient that is in the shortest supply relative to its demand. In other words, even if all other nutrients are available in abundance, plant growth will be limited by the nutrient that is deficient.
11) Cation Exchange Capacity (CEC) is a measure of a soil's ability to retain and supply cations to plant roots. It represents the soil's capacity to hold positively charged ions, such as calcium, magnesium, and potassium, and release them for plant uptake.

Which landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform?
volcanic soil
cinder cone
caldera
lava plateau
Answer:
C. Caldera
Explanation:
The landforms that result When erosion occurs as a result of volcanic eruptions, yet deposition does not play a direct role in the formation of the landform, is the caldera.
What is caldera?When a volcano starts and founders, it goes forth behind a large-mouthed depression known as a caldera.
During a volcanic eruption, magma from beneath the volcano's magma chamber is expelled, frequently violently.
When the magma chamber empties, the help supplied by the magma inside the chamber vanishes.
The resulting landforms are Calderas form when erosion occurs as a result of volcanic eruptions, but deposition plays no direct role in the formation of the landform.
Therefore, option C is correct.

Explain how different plate interactions produce different features at those boundaries.
Answer:
Plate interactions
Explanation:
When two plates collide and one goes under the other, trenches are formed like the trenches in the Pacific Ocean. These can also form volcanoes due to the melting of the plate as is goes under the other.
When two plates collide and neither give way to the other, mountains are formed like the Himalayas.
When two plates are pulling away from each other, they form ridges because of the molten magma that is dragged up with the plates. One ridge is found in the Atlantic Ocean.

___________ migration is choosing to move closer to your job because you currently live across town. *
Local
National
Voluntary
International
Involuntary
Answer:
The correct answer is Local.
Explanation:
This is correct because you are moving locally inside the same city, which means that you are not moving out of the state or something like that.
National is wrong because it means moving across the state.
Because of the same it is not international, because it would mean moving out of country.
It can't be involuntary you are choosing to move.
That is why the answer can also be voluntary, because you are the one who is choosing.
Determine the value of x, the exterior angle of the regular polygon.
Answer:
51.4°
Explanation:
The number of sides of the given polygon = 7
To find the sum of angles in this polygon, we use the expression below;
(N - 2) x 180;
N is the number of sides
So,
Sum of angles here = (7-2) x 180
= 5 x 180
= 900°
Each angle will be [tex]\frac{900}{7}[/tex] = 128.6°
Since angle x is on a straight line with one of the interior angles;
Angle on a straight line = 180°
128.6 + x = 180
x = 180 - 128.6 = 51.4°

When governments are unstable, humanitarian problems often result. Describe some of these problems in a
paragraph of at least five sentences.
Answer:
Humanitarian problems like increased poverty, famine, and refuge crises, poor health care, and lack of clean water often occur. The increased poverty factor is often caused by the overall lack of money that the country has. Things like famine are caused by the initial poverty-stricken state of the country, and lack of land and water to produce food. As more people leave the country to escape the harsh living conditions of the country, refugee camps in nearby countries begin to overpopulate, and living conditions there worsen.

Identify the economic system with the widest selection of consumer goods. Identify one other characteristic of this type of economi
system.
Answer:
The economic system with the widest selection of consumer goods is the market economy.
Explanation:
The market economy is an economic system in which all of the business is private ownership, while the government has only regulatory authority. In this economic system, the production of goods is in accordance with the demand from the consumers. The competition is very high, thus for a business to succeed and persist needs to make products with the highest possible quality for the lowest possible price.
One other characteristic of the market economy is that every business has total freedom when it comes to choosing what to produce and what amount to produce it. The businesses don't produce equally for all areas where they deliver their products, but instead, there are big differences in the distribution. This is based on how much of their products are in demand in a particular area, where there is higher demand there is bigger delivery and vice versa.

The paths of water parcels initially flowing downhill from the central region of the mound in the Northern Hemisphere turn counterclockwise, producing an overall circulation. This is indicated by the black arrows in the animation.
In the western portion of the dome of water, where the contour lines are more closely spaced, it can be assumed that the pressure gradient force is the strongest. This is because the closely spaced contour lines indicate a steeper slope, which corresponds to a stronger pressure gradient force.
Water parcels in the Northern Hemisphere flow counterclockwise from the central region of the mound, and the western portion of the dome has the strongest pressure gradient force due to closely spaced contour lines.

O 6 million miles
O 6 trillion miles
O 12 million miles
O 12 trillion miles
Answer:
6 trillion miles
Explanation:
There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years.
