To show the carbon cycle in a bottle ecosystem. A bottle ecosystem is to recreate an ecosystem inside a bottle or a container to study them or just for decoration. ... The second thing that happens in the ecosystem is that the pondweed absorbs the carbon dioxide converting it into oxygen by the process of photosynthesis.
Answer:
c. Protons, electrons
Explanation:
The number of these electrons in a neutral atom is equivalent to the number of protons.
Since protons have positive charge, they balanace the negative charge of electrons. Electrons have same level of charge per particle as a proton.
Neutrons posses no charge, so in a "neutral atom" the number of proton is equal to that of electrons, othermeans it will not be neutral.
When a electron is removed by natural or artificaial means , an ion results which is an electrically charged particle. It also happens some atoms take additonal electrons once they were previously neutral. They can also lose electrons and become positively charged,
This is true. Scientists cannot agree on one definition of life so far. Therefore, this is true.
