Explanation:
The gene pool is defined as the set of all genes in population. The larger the genetic pool in population is, the grater genetic diversity is so the population can survive intense process of selection. On the other hand, low genetic diversity can cause reduced biological fitness and the chance of extinction is increased.
Answer;
The above statement is false.
Explanation;
The correct statement would have been;
The half life of an element of an element is the amount of time is it takes for half of radioactive isotope to decay.
-Isotopes are atoms of the same element that have the same atomic number but different mass number. Radioactive decay happens when an unstable atomic nucleus of an isotope spontaneously changes to a lower-energy state and spits out a bit of radiation.
-Half life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate or undergo radioactive decay.
Answer:
The answer should be solid
Answer:
True
Explanation:
Lewis structures are diagrams that represent the valence electrons of atoms within a molecule. These lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.
