Answer:
Chemical weathering
Explanation:
Chemical weathering is the process when rain chemicals react with rocks and minerals. In this process, the rocks are weakened. This chemical happening provokes the chemical reaction in the rock or in the mineral.
Chemical weathering is a spontaneous process and it leads to a more stable state for natural materials under a given set of conditions.
Incomplete dominance can happen in flowers such as snap dragons where a red flower plant and a white flower plant have an offspring that is neither red nor white but is a mix so in this case it would be pink. It does not support the blending theory as it does not get its colour from the dominant plant in this case but from both.
Answer:
It is quite difficult to picture a pseudoscientist—really picture him or her over the course of a day, a year, or a whole career. What kind or research does he or she actually do, what differentiates him or her from a carpenter, or a historian, or a working scientist? In short, what do such people think they are up to?
… it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
The answer might surprise you. When they find time after the obligation of supporting themselves, they read papers in specific areas, propose theories, gather data, write articles, and, maybe, publish them. What they imagine they are doing is, in a word, “science”. They might be wrong about that—many of us hold incorrect judgments about the true nature of our activities—but surely it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.
<h3>
Why is choosing a direction necessary? </h3>
It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can.
When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.
<h3>
What is gene flow?</h3>
- Gene flow refers to the processes by which genes are transferred from one group to another.
- Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
- Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
- Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.
