Explanation:
Many birds, such as geese, seasonally fly to warm places when the weather gets cold. They then return when the weather warms. This process is called migration. ... Migration enables many animals to move to places where it is easier for them to survive.
I believe true because the Precambrian is the first geologic time, going back 4600-570 years ago, meaning it should contain the earliest of things.
The correct formulae is CCl4
The genotype of the Q gene is homozygous dominant because it has 2 dominant genes and when a genotypes has two of the same type of genes it is homozygous. If it has different genes it is heterozygous.
hopefully this helps
