Answer:

Ions are atoms with a positive or negative charge.

Explanation:

Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.

The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.

The other options are not correct because of:

There are usually as many or more neutrons than protons.
Uncharged atoms are neutral.
The number of protons or neutrons does not affect the electric charge of the atom.
Atoms that joined in fixed proportions can form molecules.

The process of converting the "message" of mrna into a sequence of amino acids is called:

olganol [36]

This process is known as translation

The process begins with messenger RNA (mRNA) giving instructions to amino acids. These instructions are sent with the help of transfer RNA (tRNA).

The amino acids form a chain called a polypeptide (proteins are made up of one or more polypeptide chains)

I have attached an image that will help your understanding of translation

I hope this helps! I'm happy to help with any other questions you might have :)

Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms .

Rus_ich [418]

The characteristics that scientists used to classify living organisms into six kingdoms include the following:
1. Cell type: living organisms are classified into prokaryotes and eukaryotes based on the presence of nucleus and distinct arrangement of the organelles in their cells.

2. Mobility: living organisms are categorized into kingdoms based on their ability or inability to move about.

3. Cell structure: the cells structure was used to divide living organisms into plants and animals. Those living organisms that have cell wall are classified as plants while those who do not have cell wall are classified as animals.

4. Number of cells: living organisms that are made up of only one cell are classified as unicellular while those with many cells are termed multi cellular.

5. Reproduction method: living organisms are classified based on whether they reproduce sexually or asexually.

6. Manner of obtaining energy: living organisms that can prouduce their own food are called autotrophs while those that can not produce their own foood are termed heterotrophs. Plants are essentially categorised as autotrophs while animals are described as heterotrophs.
