4. What are the characteristics of<br> the particles of matter?
mojhsa [17]

Not sure how in depth or what level of particles but I will go as deep as I know. The matter that makes up the world is comprised of 12 particles which are known as fermions. There are 12 fermions which are made up of 6 quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Technically, only the up quark, down quark, electron, and electron neutrino are necessary to create all known matter since others would simply be very unstable and decay into those particles. The other type of particles are known as Bosons. These particles transmit forces and all sorts of different interactions. I have included a photo from online which describes the main characteristics of each elementary particle.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

these are the definitions so hope it helps you:

<u><em>carbon cycle</em></u><em> - Pathways through which carbon is recycled through the biosphere. </em>

<u><em>cellular respiration</em></u><em> - Process of breaking down glucose to obtain energy in the form of ATP. </em>

<u><em>photosynthesis</em></u><em> - Process by which specific organisms (including all plants) use the sun's energy to make their own food from carbon dioxide and water; process that converts the energy of the sun, or solar energy, into carbohydrates, a type of chemical energy. </em>

Stels [109]
D is correct.

Another equivalent explanation currently used is the watermelon. Thomson believed (if using the watermelon as an example) that the red part, was some kind of positive matter and the seeds where electrons - electrons stuck to a positively charged matter.


Hope it helped,
