Answer:

Heat is a form of energy that moves from hot things to cold things. In other words, heat is energy that flows from objects with a high temperature. Temperature is the average kinetic energy of the particles in an object and is measured using a thermometer.

Heat can move from object to object in three ways. One way that heat flows is called conduction, which occurs when two objects are touching.

In conduction, the particles in the high temperature object are vibrating quickly compared to the low temperature object. When the particles in the high temperature object bump into the particles in the low temperature object, the low temperature object's particles begin to vibrate more quickly. Another form of heat transfer is convection, which occurs in liquids and gases. In convection, the part of the liquid or gas with high temperature is less dense than the part with low temperature so the high temperature parts rise and the low temperature parts sink.

In both conduction and convection, heat is transferred through a material. However, heat energy can also travel through empty space in a third way called radiation, which is how heat travels from the sun to the Earth.

radio waves, an electromagnetic wave  is used for long-distance communication

microwaves, an electromagnetic wave with waves shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes

A nonrenewable resource

Gold is a metal formed naturally. It is not so abundant in earth and become exhausted when consumed through excavation. Hence, gold is a non-renewable source.

Renewable resources are those which never ends as we consumed and can be recycled the used amount as well. Whereas non-renewable resources are no more when we exhausted the existing amount.

Solar energy, wind energy, hydrothermal energy etc are renewable sources. Metals, minerals, nuclear power, coal, fossil fuels etc. are examples of non renewable resources.

Gold is a natural metal used have significant importance and expensive. It cannot made from other substances. Hence, once all the existing gold are taken through mining there will be no more gold. Hence, it is a non-renewable resource.

Answer:

During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.

The very important phase in mitosis called the  metaphase is most useful in the healing process. In this phase the damaged cells are repaired or replaced with the new cells.

All eukaryotic cells undergo mitosis (plants, animals, and fungi). It is the method through which a plant, an animal, or a fungus renews and grows its cells. Our bodies are always undergoing it.  

The ongoing death of cells is known as apoptosis (programmed cell death). These cells need to be regularly replenished in order for you to be alive and properly functional. This process depends on mitosis.

We are able to expand, recover from injuries, and replace damaged cells because of mitosis. Since this is the only method that these cells can replicate, mitosis is also crucial in creatures that reproduce asexually. The most useful phase in  mitosis that is responsible for healing is metaphase.

Synthetic polymers are human-made polymers, often derived from petroleum oil. From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. They are commonly found in a variety of products worldwide.

Explanation:

The geocentric model represents the earth at the center of the universe. The model couldn't explain the backward and loop movement of the planets. Thus, option d is correct.

The geocentric model was an early cosmological theory given by Eudoxus and Aristotle that defined Earth at the center of the universe with planets and the Sun revolving around it. It stated about the circular path followed by the celestial bodies.

The people on the Earth do not feel the planet moving, and hence it was assumed that it was the center. The circle being perfect was considered to be the motion of the revolution.

The model cannot establish the backward and loop-like movement of planets like mars where they move ahead and a little back when revolving.

Therefore, option d. the backward movement of the planets did not support the geocentric model.

A cell has lost the ability to release energy from glucose for the cell to use. Mitochondria would this energy conversion be performed. Therefore, option B is correct.

Small structures found in the cytoplasm of a cell. Mitochondria produce the majority of the cell's energy and have their own genetic material that differs from the genetic material found in the nucleus.

The classic role of mitochondria is oxidative phosphorylation, which produces ATP by utilizing the energy released during food oxidation. In turn, ATP serves as the primary energy source for the majority of biochemical and physiological processes.

Our glucose molecules are transported by mitochondria through a process known as cellular respiration, which is essentially just a process of breaking down and converting glucose by combining oxygen with a glucose molecule.

Thus, option B is correct.
