Gradualism, a theory in both geology and biology, suggests that significant changes occur through slow, continuous processes over long periods of time. This contrasts with the concept of punctuated equilibrium, which describes long periods of stasis interrupted by rapid changes. Both gradualism and punctuated equilibrium are observed in the evolutionary process.
The theory that the student is referring to seems to be the concept of gradualism in the context of evolution and geology. Gradualism is the idea that substantial changes in species or the earth's geology can occur through slow, sustained processes over long periods of time. This runs in contrast to the concept of punctuated equilibrium, which describes long periods of stasis or no change, interrupted by rapid bursts brought on by drastic environmental changes.
Some ideas of gradualism were initially influenced by 18th-century geologists like James Hutton and later Charles Lyell, who proposed that geological change occurred slowly due to continuous small changes. These thoughts dramatically influenced Charles Darwin's evolutionary theories. Darwin adopted a gradualist approach in his understanding of evolution, proposing that given enough time, slow and subtle processes could produce significant biological changes within species.
However, both gradualism and punctuated equilibrium models are seen in practice, with evidence from the fossil record showing both long periods of slight, gradual change and shorter periods of rapid, significant change. In conclusion, evolution is not a linear process but a branching one and involves elements of both gradualism and punctuated equilibrium.

In DNA base pairing, adenine (A) base pairs with thymine (T) using two hydrogen bonds, and guanine (G) base pairs with cytosine (C) using three hydrogen bonds.
The four nitrogenous bases are A, T, C, and G. They represent adenine, thymine, cytosine, and guanine. The four unique bases pair together in a manner known as corresponding matching. Adenine generally coordinates with thymine, and cytosine generally coordinates with guanine.
A unit of two bases in a particle of DNA or RNA. In DNA, adenine generally coordinates with thymine (A-T), and guanine generally coordinates with cytosine (G-C). RNA is something very similar, then again, actually adenine generally coordinates with uracil (A-U).

Explanation: im sure this is the answer 100% pls mark brainliest!
The correct answer is Robert Hooke.
The invention of the microscope is one of the most essential discoveries ever made by the scientists. Robert Hooke in 1965, witnessed a slice of thin cork beneath the microscope and witnessed minute spaces, which appeared like small rooms combined together.
As they appeared like the tiny quarter of prisoners or monk he named the structures as cells.
This was Scientist Hooke... he was once in jail and that may have been one of the reasons he made the connection to the cells shape and called them what they are today :)
lol we just learned this biology earlier this week and I'm so proud of myself that I remember :)
