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.

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.

A force that tends to pull together the matter in stars is : ( A ) Gravity

Gravity is a force which pulls object together / towards each other. gravity is an invisible force therefore it can not be seen or felt. for matters of an object to remain in place the force of gravity pull the matters of the object/compound together as seen in the matter in stars.

Hence we can conclude that A force that tends to pull together the matter in stars is : ( A ) Gravity

While Earth Science is centered on Earth and its systems, Physical Science has a broader scope that includes the study of the universe and fundamental principles of matter and energy. Both fields share common methodologies and foundational principles, and they often overlap in areas such as the chemistry of the Earth's atmosphere and oceans or the physics of Earth's magnetic field.

Similarities between Earth Science and Physical Science:

1. Both Earth Science and Physical Science involve the study of natural phenomena and aim to understand the physical world around us.

2. They both use the scientific method to conduct experiments, make observations, and draw conclusions.

3. Both fields rely on principles of physics and chemistry to explain the processes and interactions within their respective areas of study.

Similarities for Earth Science:

1. Earth Science focuses on the study of Earth's physical components, such as its atmosphere, oceans, and landforms.

2. It includes the study of natural disasters like earthquakes, volcanoes, and hurricanes, which are directly related to Earth's systems.

3. Earth Science also encompasses the study of Earth's history, including the fossil record and geological time scales.

Differences for Physical Science:

1. Physical Science is broader in scope, encompassing all aspects of the physical world, not limited to Earth. It includes the study of the universe, matter, and energy.

2. It is divided into two main branches: physics, which deals with the properties and nature of energy and matter, and chemistry, which focuses on the composition, structure, properties, and changes of matter.

3. Physical Science often involves more abstract concepts, such as quantum mechanics or thermodynamics, which are not exclusive to Earth.

Differences for Earth Science:

1. Earth Science is more focused on the practical and applied aspects of science that are directly related to Earth and its immediate surroundings.

2. It includes disciplines such as meteorology, geology, oceanography, and environmental science, which are specific to Earth's systems and phenomena.

3. Earth Science is interdisciplinary, integrating biology and ecology to understand how life interacts with Earth's physical and chemical processes.

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.

Answer:

The scientists who postulated the cell theory were:

-Robert Hook: he was the first scientist to use the word cell, he observed cork and he calls cells  the the divisions he saw.

- Leeuwenhoek: he built biconvex lenses and with them he observed microorganisms such as bacteria and protozoa and cells such as sperm and red blood cells.

- Schleiden: he studied embryonic cells and discovered the nucleolus

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'.

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.
