Answer:
Mutation
Explanation:
Mutation creates new genetic variation in a gene pool. It is how all new alleles first arise.
Answer:
Adaptation is correct
Explanation:
Remember all the species changes little by little because of the genetic changes (like in this case) or because need to adapt the quantity of food (in some seasons like camels) or because they need to adapt to environmental conditions (like in hotter summers or colder winters in some regions).
In all these cases, the changes occurred through the pass of time and could be a result in changes in their morphology or physiology.
Answer: oxygen interacts with the sodium forming ion-dipole interaction.
Explanation:
Ion-dipole force is from when a polar solvent interactions with ions.
When water molecules and a sodium ion react the water molecules align so that the oxygen can interact with the sodium ion. The oxygen atom in the water molecule has a slight negative charge and is attracted to the positive sodium ion generating an ion-dipole interaction.
They have already had it and carrier of it with asymptotic and never knew or if they catch after rains peoples systems are low. In immune systems that is the natural fighter that cross the blood and brain. Barrier if low they can be prone to catching it as well.
But the answers provided im not seeing the real answer as in they put the problem that caused a. Disease in a vaccine only so much of it and add antidote example flu shot . It attacks some people immune system and they get sick because of injecting it into them but the belief is of catching it after I don’t believe I believe either your body can handle it or it does not and rejects it in the blood brain barrier so if recieved then you will get sick after getting the immunization
Answer:
it is referred to as genetic variation
