Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
How is a spark from touching a doorknob the same as a bolt of lightning
Explanation:
That little spark you get when you touch the doorknob is essentially a miniature lightning bolt. When rain clouds move through the air, they build up positive and negative electric charges (Figure 7). So clouds have static electricity too! And when enough charge builds up, electric charges jump between the cloud and the ground.

Answer:
The Sun
Explanation:
Answer:
The sun
Explanation:
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things.
How does the Earth's atmosphere interact with the sun's rays? A. The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth. B. The sun is outside of the atmosphere and doesn't interact with it at all. C. The atmosphere deflects the sun's poisonous elements. D. None of the above
Answer:
The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth
Explanation:
This is because the atmosphere also interacts sun radiations that comes in contact with through a process called molecular scattering. Light rays are very minute and there are alot of small molecules that float in the atmosphere and when light comes from the sun, the smaller molecules scatter the Ray's and it warm the Earth. Huge numbers of small molecules float in the atmosphere. There is a layer called ozone which absorb sun radiations.

called?
A. Chromatin
B. Chromosomes
C. Chlorophyll
D. Sister
Chromatids
A. Chromatin is the uncoiled, stringy form of DNA in the nucleus of a cell.
What is chromatin?It is made up of DNA molecules and associated proteins, such as histones, that help to package and organize the DNA into a more compact structure. Chromatin can take on different forms, ranging from loose and loosely coiled to tightly packed, depending on the stage of the cell cycle and the specific needs of the cell.
When a cell is preparing to divide, the chromatin condenses and forms distinct structures called chromosomes, which can be visualized under a microscope. Chromosomes contain the genetic information that is passed from one generation to the next.
