Answer:
Proteins
Explanation:
There are proteins in the membrane that have channels for large polar molecules to move into or out of the cell since the plasma membrane is made of a phospholipid bilayer where the inside is non polar. This means large polar molecules need help from proteins to cross the plasma membrane.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
Answer:
False
Explanation:
All bacteria contain peptidoglycan in the their cell wall; the major component of peptidoglycan is the N-acetylmuramic acid. The peptidoglycan in bacteria helps to protect the bacteria plasma membrane and cell as a whole from environmental stress as well as maintaining its cell morphology.
In this case, the unicellular organism that was discovered is most likely an archaea. Archaea are organisms that have a semi rigid cell wall with the absence of peptidoglycan.
Explanation:
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
