When farmers harvest crops, a lot of the plant material is also removed. Little is left to decay and return nitrogen to the soil. If the soil stays this way, it will start producing fewer crops. Fertilizer contains the nitrogen compounds that are essential for plant growth. It can be used to replace the nitrogen in the soil to ensure the growth of healthy crops.

The answer is C or liquid because liquid particles do not bonce off each other and liquids are Particles are loosely together  Indefinite shape and definite volume  Able to flow and Dan said "Small pea seeds move around each other but do not bounce off" so he is referring those small pees as molecules and he did say the pee seeds move around each other and bounce off and please correct me if am wrong and not to throw you under the bus lori0 but mullins is a town in south carolina

Amino acids form chains called peptides, which can join together to form polypeptides. When many amino acids are linked, or when multiple polypeptides combine, they form proteins. The characteristics of a protein are determined by the sequence and arrangement of amino acids in the chain.

Chains of amino acids form short chains called peptides. These peptides can join together to form longer chains, which are referred to as polypeptides. When the number of amino acids joined together becomes very large, or when multiple polypeptides are used as building subunits, the resulting macromolecules are known as proteins.

Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond, which is formed by dehydration synthesis. Dehydration synthesis in this context involves the carboxyl group of one amino acid combining with the amino group of another releasing a water molecule, hence the term dehydration. The process can continue, linking numerous amino acids together in a chain.

The sequence, number, and specifically the arrangement of these amino acids in the chain ultimately determines the protein's unique shape, size, and function.

Chlorophyll, the green pigment located in the thylakoid membranes of chloroplasts, is essential for photosynthesis as it absorbs sunlight and converts it into chemical energy used to produce plant sugars.

Chlorophyll is a vital green pigment found within the thylakoid membranes of chloroplasts, the organelle where photosynthesis occurs. It plays an essential role in the process of photosynthesis by absorbing sunlight and converting it into chemical energy. This energy is then used, along with water and carbon dioxide, to produce sugars for the plant, which are essential for its growth and development.

In chloroplasts, chlorophyll molecules are meticulously embedded in the thylakoid membranes, and when they capture light energy from the sun, they energize electrons within the chlorophyll molecule. These high-energy electrons are then used in a series of complex reactions to generate energy-rich compounds like ATP and NADPH, which subsequently fuel the Calvin cycle to synthesize sugars.

The presence of chlorophyll in plants also contributes to their green color, as it reflects green wavelengths of light while absorbing other wavelengths, particularly those in the blue and red spectrums, which are crucial for photosynthesis.

Explanation:

Weight is defined as the force that the gravity exerts on an object due to its mass. So higher the gravity higher the weight and lower the gravity lower the  weight. The object on planet 'a' that has a force of gravity that is weaker than that of the planet 'b' will have less weight than the object on planet 'b'.  

Graph 3  represent the beetles living on the light colored trees and graph 5 represent the beetles living on the dark colored trees.

Options B and D are correct

These beetles are likely to experience selective pressure favoring lighter coloration because lighter-colored beetles would be better camouflaged against the light bark, making them less visible to birds. Over time, natural selection may lead to an increase in the frequency of lighter-colored beetles in this population.

In the same way, beetles on the dark-colored trees may experience selective pressure favoring darker coloration. Darker-colored beetles would be better camouflaged against the dark bark, providing them with a better chance of avoiding bird predation. Over time, natural selection may lead to an increase in the frequency of darker-colored beetles in this population.

Final answer:

The difference between primary and secondary succession is that primary succession occurs on newly formed land with no soil, requiring pioneer species to create soil, while secondary succession occurs on disturbed land with existing soil, allowing for faster recovery.

Explanation:

Ecological succession is the process where a community experiences a sequence of changes with the appearance and disappearance of species over time. The main difference between primary succession and secondary succession lies in the condition of the environment where the succession begins.

Primary succession occurs in areas where no soil exists because it's a newly formed or exposed environment, such as land formed from lava flow or locations where glaciers have retreated. Here, the environment is colonized by pioneer species which can grow in such harsh conditions and gradually create soil by breaking down rock and contributing organic matter as they die off.

In contrast, secondary succession happens in areas that were once home to existing life but were disturbed by events like wildfires or human activities. In these cases, soil is already present, and remnants of the destroyed community provide a basis for new growth. Succession in these situations tends to be faster than primary succession because the soil already contains nutrients needed for plant growth.

Final answer:

The best example of a hypothesis from the given options is 'If temperature is increased, then ice will melt more quickly.' This statement is testable and formatted correctly (If... then...), which aligns with the definition of a hypothesis in scientific inquiry.

Explanation:

To identify the best example of a hypothesis, it is important to understand what constitutes a hypothesis. A hypothesis is a suggested explanation that can be tested and is typically formatted as 'If... then...'. Therefore, the best example of a hypothesis from the options provided is, 'If temperature is increased, then ice will melt more quickly.' This statement sets up a condition (increased temperature) and predicts an outcome (ice melting more quickly) that can be tested through experimentation.

An example to illustrate the concept could be how you can dissolve sugar more rapidly in hot water, which demonstrates the principle that certain processes increase with temperature. To further explain, if a student approaches a warm classroom and asks why it is warm, proposing a hypothesis such as 'The classroom is warm because no one turned on the air conditioning' follows the correct structure. It is testable because the student can turn on the air conditioning to see if the classroom's temperature decreases.

Final answer:

Early man desalinated sea water primarily by boiling it off to extract salt, a process with historical evidence such as the Han-era deep drilling for salt brine. Other desalination methods throughout history have included freezing and reverse osmosis.

Explanation:

Early man removed salt from sea water by boiling off the water. This desalination process was essential for producing salt for food preservation and nutrition. Historical evidence, such as the Han-era practices, shows that ancient civilizations used techniques like deep drilling for salt brine and then boiling the water with natural gas to extract salt. This process can be likened to distillation, where the principle involves evaporating the water and then condensing it to leave behind impurities.

Moreover, desalination methods have evolved where various scientific principles have been applied. For instance, sea water can also be purified by freezing, a process where ice forms and leaves the salt and other impurities in the liquid water, or through reverse osmosis, which uses a semi-permeable membrane to separate salt from water.

Answer:

The correct answer will be- tension

Explanation:

Centripetal force is the force acting on the object moving in a circular path with direction towards the center. The centripetal force causes the object to follow a curved path.

Three forces together act on the string with key: Tension (a force acting on the key chain due to string), gravity (the downward force), and friction (resisting force). Out of these the main source of action of centripetal force is the "tension" applied by the string on the key-chain.

Thus, tension is the answer.
