The process of turning on the expression of genes in response to a substance in the environment is called epigenetic change.

Expression of gene is the turning on of the gene. This means that the gene is transcribed to synthesize the m-RNA and then the m-RNA is translated to from the proteins. Proteins are the actual structures that  carry the information from the DNA and execute in the body.

Epigenetic changes are those that happen on the structure of DNA and regulate the expression of the genes. This can be the enhancement of gene expression or the repression. These changes are not heritable and are also temporary.

Microvilli are the structures of fingerlike projections that greatly increase the absorbing surface of the cells.

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.

Therefore the structure that increases the absorbing surface area is called microvilli.

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.

If a cell has a relatively high energy need, you would expect it to have more mitochondria than a cell with a lower energy need.

Mitochondrion:- Mitochondrion is a double-membrane-bound organelle, where energy is produced through cellular respiration. It is present in the cytoplasm of a cell and generates adenosine triphosphate (ATP), which is the main energy module of a cell. For this reason, mitochondrion is known as the "Powerhouse of the cell".

If a cell has a higher energy need than others, it is required to have more numbers of mitochondria in that cell, since more mitochondria will produce more energy.

Thus we can conclude that, if a cell has a relatively high energy need, you would expect it to have more mitochondria than a cell with a lower energy need.

Others, such as the DNA testing, were they not available in Darwin's time, but are used by the scientists today to learn more about the evolution.

The Natural selection is the mechanism of the evolution. Organisms that are more adapted to their environment and are more likely to survive and they pass on the genes that was aided their success. This process was causes species to change and then diverge over time.

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.

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.

Option D: The cells in the nervous system that handle information processing are called neurons.

Nerve cells, often called neurons, are the building blocks of the nervous system. They interact with the information and transfer this information along various distances through electrical impulses. The nervous system is generally made up of two types of cells: nerve cells and glial cells. Glial cells are the supporting system of neurons. The nervous system is broadly divided into two categories:

The central nervous system (CNS) contains the brain and spinal cord

The peripheral nervous system (PNS) contains neurons and their parts such as sensory neurons and motor neurons.

Analysis of the information brought in by sensory neurons is done in CNS while PNS works as transportation for these signals from one neuron to another. Motor neurons carry the signals out of the CNS after analysis.

Information processing in the nervous system is handled by neurons or their parts like interneurons that connect one neuron to another in the CNS.  These signals are then transferred by motor neurons to respond to stimuli.
