You would find scales on a bird is it feet
Number 4 should be mitosis
The bulldog ant has a diploid number of two chromosomes. Therefore, following meiosis, each daughter cell will have a single chromosome. In addition to mutations, genetic diversity might be generated in this species due to (C) crossing over and random fertilization.
There are some points during sexual reproduction which might increase the chances of a genetic diversity.
During meiosis I, crossing over during prophase produces sets of chromosomes having new combinations of alleles.
Genetic diversity might also generated by random fertilization of the gametes created through meiosis. Any of the genetically distinctive sperm produced by a male might fertilize the genetically distinctive egg produced by a female.

Answer:
If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.
Replacing lysine with aspartic acid is really a change in the primary structure (the sequence of the amino acids - think in a chain). But because they are really different amino acids, the effect is much more profound and will affect the tertiary structure of the protein.
Lysine has a basic, positively charged side chain. Aspartic acid has a negatively charged carboxyl group for its side chain. So, they are two very different amino acids.
Since the tertiary structure of a protein is a result of the interactions of the various interactions of the amino acid side chains, you have to think about what a swap of a basic positive amino acid with a negatively charged amino acid could cause.
For example, if the lysine side chain interacted in ionic interactions (i.e. attraction to a negatively charged amino acid), if you swap it for aspartic acid which is negatively charged it will now repel the other amino acid's side chain and that would disrupt the tertiary structure of the protein. It would also likely cause disruption to the quaternary structure as well.
If this change was in an important part of the protein (e.g. the active site of an enzyme) then it would likely disrupt the proper functioning of this protein.
If you wanted to make the least amount of change to a protein by making a mutation to that lysine amino acid, you would choose other basic amino acids which are histidine and arginine.
