Answer:
Yes, the model of the helium atom is showing an ion.
Explanation:
Helium, with an atomic number of 2, should have 2 protons and 2 electrons; however, the model only depicts 1 electron. That means the helium must have lost an electron, making it a +1 charge and an ion.

False
Explanation:

Answer:
B. introns; exons
Explanation:
Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.
