The proteins and enzymes in a boiled egg have been denatured due to the application of heat, while this is not the case in a raw egg. The denaturing of proteins is a chemical change, in which the egg's physical properties also change, for example the interior solidifies.
Gradient = difference in elevation/horizontal distance
Answer:
Evolution by natural selection
Explanation:
Most probably, the trait of being small, weak and slower did not convey advantage (or was even a disadvantage) in survival in their environment. The bigger, stronger and faster horses had an advantage and were able to survive long enough to pass down their genes to the next generation, Over succeeding generations more and more horses, therefore, became strong, bigger and faster. This is the process of natural selection at work.
Asexual reproduction involves only one parent and the offspring is identical to the parent. An example of an organism that reproduces asexually is Archaea or bacteria. Sexual reproduction involves two parents and the offspring's genes are equally contributed by each parent. An example of organisms that reproduce sexually are some land mammals. The chromosomes of a parent and offspring in asexual reproduction are identical and there is no difference in the chromosomes.
