Sodium ions and potassium ions leak slightly during resting potential. Because sodium diffuses from the outside, where it is more concentrated, to the interior, potassium diffuses in the opposite direction, because it is more concentrated inside the neuron.
Protein channels and protein pumps transfer potassium and sodium across the cell membrane. Passive transport is facilitated by protein channels. They, like tunnels, allow materials to flow from a high concentration area to a low concentration area without expending energy.

There are basically two factors that influence the resting membrane potential. One is differences in the concentration of the sodium and potassium ions across the membrane that is electrochemical gradient and second is the sodium and potassium ions permeability through the membrane.
During resting potential ions move down their gradients through the channels and result in the separation of charges which creates the resting potential. Also the membrane is more permeable to K+ ions hence resting potential will be close to the equilibrium potential of K+ ions.

The resting membrane potential, or simply the resting potential, is the voltage across the membrane of a non-signaling neuron. This is how a cell's membrane normally behaves while it is "resting."
The resting membrane potential is primarily influenced by two variables. One is the electrochemical gradient in the concentration of the sodium and potassium ions across the membrane, and the other is the permeability of the sodium and potassium ions through the membrane. Ions travel through the channels as the resting potential develops, causing the separation of charges as they go down their gradients. The resting potential will be nearer to the K+ ion equilibrium potential since the membrane is also more permeable to K+ ions. The change in electrical potential across a biological membrane when the membrane is not actively experiencing a depolarization or repolarization event is known as the resting membrane potential (RMP).

which method do scientists use to track evolutionary changes over time? responses radiocarbon dating radiocarbon dating dna analysis dna analysis potassium argon dating potassium argon dating paleomagnetic dating
Scientists use several methods to track evolutionary changes over time. One of the most common methods is DNA analysis.
which involves comparing the genetic sequences of different organisms to infer their evolutionary relationships. Another method is radiocarbon dating which is used to determine the age of fossils, and potassium argon dating which can be used to date the rocks and minerals that contain the fossils. Paleomagnetic dating is a technique used to date rocks by measuring the orientation of the Earth's magnetic field that was recorded in the rocks when they formed.DNA analysis is a method used by scientists to study the genetic makeup of organisms, and it is one of the most commonly used methods to track evolutionary changes over time. DNA, or deoxyribonucleic acid, is the genetic material that contains the instructions for the development and function of all living organisms. By comparing the DNA sequences of different organisms, scientists can infer their evolutionary relationships. This is done by comparing the DNA sequences of different species, such as the base pair sequence of a specific gene or the entire genome.

besides the transcription factors that you have learned about, what other proteins may be involved with activating a gene to be transcribed? are there any tht may speed up transcription or even repress it?
besides the transcription factors coactivator proteins are involved with activating a gene to be transcribed. this protein speed up transcription.
An activator (a transcription factor) is a specific kind of transcriptional coregulator that binds to a gene or group of genes to speed up transcription. One of the DNA regulating sequences called an enhancer or a specific DNA promoter site are the only two places where the activator's DNA binding domain can engage. In order to boost gene expression, the activator-coactivator complex must bind to the promoter in order to speed up transcription by bringing in more general transcription machinery. Depending on the kind of cell and stage of development, activators and coactivators can be used to highly selective expression of some genes. The enzyme histone acetyltransferase (HAT) is active in several coactivators.

A gene is activated to be transcribed by coactivator proteins in addition to transcription factors. Transcription is sped up by this protein.
A special type of transcriptional coregulator called an activator (also known as a transcription factor) attaches to a gene or set of genes to speed up transcription. The DNA binding domain of the activator can only attach to one of the DNA regulatory sequences known as an enhancer or a particular DNA promoter site.
The activator-coactivator complex must bind to the promoter in order to speed up transcription by bringing in more general transcription machinery and increase gene expression. Activators and coactivators can be used to extremely selectively express some genes, depending on the kind of cell and stage of development.
