B. Anions have more electrons than protons, giving them a negative charge.
D. Cations have more protons than electrons, giving them a positive charge.
Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.
Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.
La membrana de la célula permitirá el paso de materiales como el oxígeno y el dióxido de carbono, mientras que mantendrá los materiales dañinos fuera de la célula.
Unlike photosynthesis, cellular respiration occurs in all eukaryotic cells. Photosynthesis is the opposite of cellular respiration. Photosynthesis takes place in plant cells, in chloroplasts.
There are three general ways to present data and these are:
[1] Textual Method
[2] Tabular Method
[3] Graphical Method
Since Dr. Peterson has to present the medicinal properties of some plants, analytical values are not available, only accounts and qualitative results. The Graphical Method would not apply. Therefore, the most logical way for Dr Peterson to present his research is through Tabular Method. He can make a table listing down all the plants each with a description of their medicinal properties.
