Catastrophism is associated with major changes that occurs once at a time in a species while gradualism is associated with tiny changes that occurs over a period of time that finally contributes a bigger evolutionary change.
<u>Explanation:</u>
The events that are sudden, short-lived, violent occurring worldwide thereby changing the shape of the Earth is Catastrophic. This process is opposite to contrast to gradualism which is also called as uniformitarianism. This process is associated with slow and also incremental changes. Erosion is the best example for this process.
The formation of major mountain chains and great floods are some of the examples of Catastrophism. Both are associated with the changes that occurs in a species by the time taken for the changes determines whether it is Catastrophism or gradualism.

The "arrows" show the transfer of energy from the sun to other organisms. Without it we would die!
Answer:
The correct answer is A. stabilizing selection
Explanation:
Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.
So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
Answer:
olfactory lobes
Explanation:
The correct answer would be olfactory lobes.
Murky waters are generally dark, and contains very little (low) light. Fishes that live in murky water need to be specially adapted in order to be able to live in such environment. These adaptations could be in terms of:
- A well developed lucidum tapetum, a layer of protein crystals known as guanine which enables them to see through low light and act as a kind of 'night vision'.
- A well developed olfactory lobe which receives and process information from the olfactory nerve with high efficiency and generally serves to improve the sense of smell.
