When a solid transitions to a liquid, it undergoes the process of melting. This occurs when the solid is heated to its melting point, causing the particles to gain enough energy to break free from their fixed positions and move more freely, resulting in the solid structure turning into a liquid state.

· Wind, solar and hydroelectric power provide energy from sunlight, air movement and evaporation (in the form of water that rises from the ocean, falls on the land, enters rivers and subsequently passes through the turbines in dams). These processes will continue as long as there is weather on planet Earth, meaning that energy can be gained from them forever. Energy that is gained from geothermal technology is also effectively inexhaustible, because it uses the warmth of the planetary core. Inexhaustible energy sources differ from renewable energy sources because they won't be used up under any conditions.

REMEMBER:ReaDY MIX.....it helps me every time... MIX stands for Manipulated Independent X-axis......so the answer would be:Independent....hope this helps!:D

Actually since the manipulated variable is independent the the factor that would change would be the responding variable which is the dependent variable so the answer would be:

Dependent or Responding Variable

There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.

Igneous rock at the Earth's surface that is weathered and wears away is called sediment. Sediment is made up of small pieces of rock that break off and erode from the original igneous rock due to weathering processes like wind, water, and temperature changes.

Ribena is not a suitable plant fertilizer as it contains sugar and other additives that can harm plants. The high sugar content can encourage the growth of harmful bacteria and mold in the soil, leading to plant deterioration. It's best to use commercial plant fertilizers specifically formulated to meet the nutritional needs of plants.

Rice and mango together can be considered a complementary mixture, as they provide a balance of flavors and textures. The soft, sweet mango contrasts with the savory rice, creating a delicious blend of taste sensations.

An organism that obtains its food from other organisms is known as heterotrophic. Autotrophic organisms include green plants, algae and chemobacteria that live in deep water trenches. Without autotrophs- no other life woudl exist.

The real answer is a consumer.

Yes, a candle emits infrared radiation as a form of heat energy. The flame of a candle produces a mix of visible light, heat, and infrared radiation as it burns.

Elements combine to form compounds through chemical reactions. These compounds have different properties than their individual elements, resulting in a wide range of substances found in nature and synthesized in laboratories.

Oranges can grow mold better because an orange does not have any preservatives, unlike some bread and stupid idiots..., or cheese. Preservatives help the food not mold or grow fungus. -P.S. I am in 7th grade and i learned about this today in class, i am doing a project on it. Hope it answered your question.

-Oranges can grow mold, as long as mold spores are present. Mold will grow best once the orange begins to decompose (preservatives don't last forever, therefore mold may grow on any decomposing organic matter)

It depends on which Campylobacter agar base addatives you use - there are many variations. Typically the colonies round or have slightly irregular edges, they are white when small and spread to become transparent later.

The dependent variable , which is the one being measured.

No, nylon is not biodegradable. It is a synthetic polymer that is not easily broken down by natural processes, leading to its persistence in the environment. Recycling or repurposing nylon products is a more environmentally-friendly option for disposal.

Being biologically related means sharing genetic material with another individual, typically through common biological parents or ancestors. This relationship is determined by similarities in DNA sequences and inherited traits that are passed down through generations.

A prediction must be based on data or evidence, be relevant to the situation or context, and consider uncertainties or limitations in order for it to be used effectively. Predictions that are accurate, timely, and credible are more likely to be used in decision-making processes.

Chondrus crispus( Irish moss) undergoes an alternation of generation life cycle common in many species of algae . There are two distinct stages: the sexual haploid gametophyte stage and the asexual diploid sporophyte stage. In addition there is a third stage- the carposporophyte, which is formed on the female gametophyte after fertilization. The male and female gametophytes produce gametes which fuse to form a diploid carposporophyte, which forms carpospores, which develops into the sporophyte. The sporophyte then undergoes meiosis to produce haploid tetraspores (which can be male or female) that develop into gametophytes. The three stages (male, female and sporophyte) are difficult to distinguish when they are not fertile; however, the gametophytes often show a blue iridescence

The use of CNG (compressed natural gas) as a fuel in vehicles can help reduce air pollution in cities. CNG burns cleaner than gasoline or diesel, emitting lower levels of pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. This can lead to improved air quality and reduced health risks associated with pollution exposure.

Isotope can be referred to as the different versions of the SAME ELEMENT. Such as Chlorine has isotopes of Chlorine - 35 and Chlorine - 37. This will just cause the difference in mass numbers because of the difference in neutrons. Chlorine -35 has 17 protons, 17 electrons and 18 neutrons making it to have a mass number of 35 and Chlorine - 37 has 17 protons, 17 electrons and 19 neutrons making it to have a mass number of 39. Some isotopes can be used in normal chemical reactions but some cannot.

Cork is commonly used in laboratories for sealing glassware such as flasks and test tubes to prevent spillage or contamination. It is also used to provide a grip for handling hot glassware. Additionally, cork is sometimes used as a material for making laboratory stoppers and insulating surfaces.

Assuming iodine is what you are after, as a solid it is a lustrous blue black crystal.

In the gas form it is a purple violet colour.

It is an essential element in diet, and low levels cause enlargement of the Thyroid gland (Goitre), and contributes to mental retardation. It is probably the heaviest element essential in diet. The mother concentrates iodine in breast milk, so perhaps it is needed more in infancy?

One inexpensive investigatory project could be studying the effectiveness of natural mosquito repellents such as citronella, neem oil, or lavender oil compared to commercial repellents. You can set up simple experiments to test their repellent properties and effectiveness in repelling mosquitoes. This project can be done at home using basic materials and would be a practical application of applied science.
