Which of the following is TRUE

B. ONLY a theory can ever be proven.
C. Theories and laws are the same thing.
D. A theory can never become a law.
The following is TRUE about theories and laws are-
D. A theory can never become law.
All scientific hypotheses are supported by data, are testable, and—most importantly—can be used to forecast the future. Accordingly, ideas never become laws, regardless of how much evidence there is to support them. In actuality, the end purpose of science is the formulation of theories. Any (expressed) law is a theory even though it can contain some truth that can only be derived from facts or another theory.
A theory is something we can only (temporarily) believe in since we are unable to prove it. A law cannot be a fact since it usually has an undefined, universal scope, and we can only collect a limited number of observations, some of which may be nothing more than dreams.
Therefore, I would say that any scientific law is a theory, a conviction, or a hypothesis, and we should anticipate that it will be challenged, improved, or supported by... another (simpler or more compelling) idea.

Microvilli are the structures of fingerlike projections that greatly increase the absorbing surface of the cells.
What is Microvilli?Microvilli are membrane protrusions that resemble fingers and are sustained by the actin cytoskeleton. They are present in practically all cell types. An increasing amount of research indicates that the highly curved membranes of the dynamic lymphocyte microvilli play a critical role in signal transduction that triggers immunological responses.
The examination of the process that generates curvature and its functional implications in signaling, however, was impeded by difficulties in altering local membrane curvature and tracking the high dynamicity of microvilli. Recent developments in adaptive super-resolution microscopy have helped to partially overcome these technological obstacles.

Orbitals are found in or energy levels.
The primary distinction between orbitals and energy levels is that although energy levels depict the relative locations of orbitals based on the amount of energy they contain, orbitals depict the most likely path of an electron in motion around the nucleus.
The nucleus is the center of the orbits. One orbital will be larger than the others if an atom has several orbitals, or they will overlap. Additionally, an electron is most likely to be found in orbitals.
Energy levels are the name for orbitals. The main energy levels, often known as the shell, denote a defined distance from the nucleus where electrons can be found. It is represented by the number "n," and as the number's value rises, so does the average distance and energy of the electron from the nucleus.
The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). In an atom, the small, negatively charged electrons travel around the positive nucleus.

Why does the stickleback fish system investigated by dolph schluter and colleagues represent a great example of ecological speciation?
Ecological speciation is the process through which new species develop as a result of differential natural selection between diverse ecological settings.
There are currently many instances of this technique. A type of speciation known as ecological speciation results from reproductive isolation when there is less or no gene flow between two populations of a species as a result of an ecological condition. Environmental changes that a species encounters, such as behavioral modifications in predation, predator avoidance, pollinator attraction, and feeding, as well as modifications in mate preference brought on by sexual selection or communication mechanisms, are examples of ecological factors.
New species are created as a result of ecologically motivated reproductive isolation under divergent natural selection. In the stickleback fish system, they adapt instead of being blind therefore it is an example of ecological speciation.
