Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.

2, because a theory is not a law that can not be changed, and new evidence can change a theory.
The Atlas. This is the topmost vertebra, and with the axis, it forms a joint that connects the skull to the spine. These two parts of the body (The Atlas and The Axis) are special, and different from normal vertebra, because they are made to allow a greater range of motion and movement in the head. I hope this helps! Also, google is always a helpful tool to use as well. :)
Explanation:
Pride is the social community of lions where they grow, mate, reproduce, communicate, hunt etc. When male lions gets control of a new territory or a pride, they most of the times kill the cubs of the pride because they are not biologically related and do not want to waste their energy by ensuring that the cubs genes are passed on.
They don't want to be stepfathers. Female lions also will not be responsive to mating during the time they are feeding, so killing the cubs allows the male lions to reproduce.
Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents
