Answer:
Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).
Iodine is a cation because it lost one electron. The ion symbol then would be:
I ⁺
So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.
An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).
Iodine gained one electron and the ion symbol would be:
I⁻
So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.
Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).
Sulfur is an anion that gained two electrons with an ion symbol of:
S²⁻
So from the name <u>Sulfur</u><u> </u>the name will change into "Sulfide" and its name will now be <u>Sulfide ion. </u>
Answer:
DNA is nucleic acid
Explanation
Nervous System
Skeletal System
Muscular System.
The Nervous System fires electrical signals to your muscles, galvanizing them into action and making them move. The Skeletal System helps to support the Muscular System and move blood throughout your body so your body can receive oxygen. Your Muscular System in turn keeps your heart beating and helps you with locomotion.
Answer:
True
Explanation:
During the evolution of eukaryotic cells, the complexity of size and their functions increased, so that a proportional increase in the surface of the <u>cell membrane</u> would be necessary, making it possible for the cell to perform several functions at the same time.
Through differentiations of the structures, it was possible to develop intracellular membranes in the form of organelles capable of performing various functions at the same time, such as cellular respiration and digestion.
Answer:
The Law of Dominance says that when an organism is heterozygous for a trait (meaning it has two different alleles for that gene), the allele that is expressed is the dominant one. It is one of Mendel's laws of inheritance. Unfortunately, there's no easy way to just know if an allele will be dominant or recessive.
