Cell membrane (plasma membrane) acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The cell membrane, also known as the plasma membrane, is a crucial component of all living cells. It serves as a selective barrier that controls the movement of substances into and out of the cell. This selective permeability is essential for maintaining the cell's internal environment and regulating the exchange of nutrients, gases, and waste products. The cell membrane consists of a lipid bilayer embedded with proteins, and its hydrophobic interior prevents the passage of most polar molecules.
To facilitate the transport of specific substances, the cell membrane contains various proteins, including transport proteins, receptor proteins, and enzymes. These proteins help regulate the flow of ions, nutrients, and signaling molecules across the membrane. Overall, the cell membrane is a vital structure that ensures the cell's survival and functionality by controlling its interactions with the external environment.

The cell membrane acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The structure that acts as a selective barrier, regulating the traffic of materials into and out of the cell is the cell membrane or plasma membrane.
The cell membrane is composed of a phospholipid bilayer with embedded proteins that control the movement of substances in and out of the cell. It selectively allows certain molecules to pass through while keeping others out, maintaining homeostasis within the cell.
For example, the cell membrane regulates the entry of nutrients and gases into the cell, as well as the removal of waste products and excess substances. It ensures that the cell maintains the appropriate balance of substances for proper functioning.

Answer:
genetic drift
Answer:
genetic drift
Explanation:
The process of converting the genetic message from DNA into RNA is called transcription.
Transcription is the phase of gene expression in which a certain part of DNA is copied into RNA. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides to produce an RNA strand and uses a DNA strand as a template. The three stages involved in transcription are initiation, elongation, and termination.

There are five levels of cell organization recognized by biologists.
The nutrient that can be found in all organic compounds is the carbon. The reason why carbon is found in all organic compounds is described below.
Organic compounds are those chemical compounds found in living organisms which are made up of carbon-hydrogen bonds.
Carbon is the main element in organic compound since it forms its bonds. Typical examples of these organic compounds are:
Therefore, The nutrient that can be found in all organic compounds is the carbon.
