Answer:
Potential,Kinetic
Explanation:
When an object is higher up on a surface it has more Gravitational Potential Energy whilst when an object is lower down but moving fast it has more kinetic energy. So when the object moves down the ramp energy is transferred from the gravitational potential energy store to the kinetic energy store.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

What object is shown in this image?
a nebula
a red giant
a supernova
a neutron star
Answers
The object shown in the given image is a nebula. Therefore, option A is correct.
What is a nebula?A nebula can be described as a distinct luminescent of the interstellar medium, which can contain neutral, ionized, or molecular hydrogen and cosmic dust. In these regions, the formations of dust, gas, and other materials "clump" to form denser regions, which attract matter, and become dense enough to form stars.
There are several formation mechanisms for the different kinds of nebulae. Some nebulae are formed from gas that is in the interstellar medium while others are formed by stars.
Star-forming regions can be defined as a class of emission nebula with giant molecular clouds. These produce a molecular cloud that collapses under its weight, producing stars.
Most nebulae have vast sizes while some are hundreds of light years in diameter. The Orion Nebula is the brightest nebula in the sky and occupies an area twice as the full Moon, and can be viewed with the eye.

Based on your knowledge of chemistry, explain what the reactants and the products are of the chemical reaction, why the masses on the scale are the same, and what type of chemical reaction indicator was given to show that a chemical change has taken place.
Answers
Ch4 (methane)
2O2 (oxygen)
These are the reactants because they are on the left side of the arrow
Products:
CO2 (carbon dioxide)
2H2O (water)
They are on the right side of the arrow and are produced from the reactants
The masses in the scale are the same bc according to the law of conservation no mass is either created nor destroyed but is simply chemically rearranged causing for them to have the same mass on both sides, if they were not equal some part of the chemical reaction is wrong because of the law.
A chemical reaction has taken place because in the product side chemicals have been rearranged and that cannot be undone physically

Answer:
Stirring
Explanation:
Stirring allows for the homogenization of mixable liquids and the stir-up of solid particles in liquids. Differences in temperature or concentration are balanced more efficiently during stirring. Additionally, the stirring of liquids accelerates the dissolution processes or increases the speed of chemical reactions. Stirring is used in all areas of the pharmaceutical and food industries, biotechnology, and wherever chemical products are processed and manufactured.
What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Answer:
When an organism use chemical energy to move, some of it is lost as metabolic heat.
The term chemical energy is defined as the energy which is stored in the bonds of chemical compounds. It is given in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction.
Energy changes as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are taken by organisms from the next level.
Thus, Metabolic heat is lost when an organism uses chemical energy to move.

D. They make seeds for reproduction.
Answers
Answer:
B.
Explanation:
A cactus stores water in its stem, which allows it to survive and thrive in desert-like environments. Its stem is made up of thick, spongy tissue that helps to absorb and retain large amounts of water. This stored water is then used to keep the cactus hydrated during times of drought and heat.

Occurs when the particles in one part of an object vibrate more and collide with neighboring particles, making them transfer energy.
Different materials conduct heat at different rates. Metals are generally good conductors of heat compared to non-metals (paper, wood, and plastics).
Solids are better conductors than liquids because the particles in solids are tightly packed together.
What is thermal energy?Thermal energy is the energy associated with the random motion of particles in a substance. It is a form of kinetic energy created from the vibrational and rotational motion of atoms and molecules in a substance.
All objects contain thermal energy and when two objects of different temperatures are in contact, heat flows from the hotter object to the colder object until they reach a state of thermal equilibrium. Thermal energy is used in many applications such as heating, cooling, and even cooking food.

occurs when an outgrowth forms on an existing sponge and develops there until it can grow on its own. Then, it drops off of the parent to become an adult.
Answers
Answer:
1. The last word is Regeneration and the method of reproduction is Fragmentation
2. This method is Sexual Reproduction
3. This Method is called Budding.
Explanation:
1. Fragmentation is a form of asexual reproduction in which a parent organism breaks into pieces, and each piece can grow into a new individual.
2. In sponges, sexual reproduction is an external process that occurs in the surrounding water.
3, Budding is a form of asexual reproduction where a new individual grows out from the parent sponge, eventually detaching and becoming a separate organism.
The first word is fragmentation and the process is regeneration. For the second one, the process is known as broadcast spawning. The final answer is called budding.
Fragmentation: It is a type of asexual reproduction seen in organisms such as plants, fungi, etc. The organism can break into smaller fragments, following which, each of the new fragments can develop into a new organism on its own through regeneration. The fragments will be genetically identical.
Broadcast Spawning: It is a form of fertilization that takes place externally. It is mostly seen in sponges, which are located in the water. In the case of sponges, one sponge releases sperm into the water, while the other will draw in the sperm along with the water flow through its body.
Budding: It is a form of asexual reproduction. In this process, a new organism is able to develop from an outgrowth or bud from the parent organism. The bud will then grow and eventually detach from the parent body to become an independent organism.

Answer:spectrum
Explanation:
Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.
So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.
But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.
So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?
