Answer:B.) Substitution
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA molecule. Substitution leads to a point mutation if only one nucleotide is replaced by another.
A substitution mutation occurs when one or more nucleotides in a DNA sequence is replaced by another nucleotide.
Example of substitution is in sickle cell hemoglobin in which valine replaces glutamate at position six in the two beta chains of hemoglobin. In a normal hemoglobin, the two beta chains of hemoglobin have glutamate at the sixth position but in a sickle cell hemoglobin, valine is found at position six on the two beta chains. This is also an example of a point mutation.
Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
- Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge.
- Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.

The answer is 22 hydrogen atoms.
This is a simple sugar compound formula <span>Cn(H2O)n</span>
If you have 11 oxygens that means that the second n in the formula will be 11.
Notice that the H (hydrogen) is followed by a 2, that means that the 11 put outside the parenteses will be multiplied by 2.
11 x 2 = 22 hydrogen atoms
