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.
The frontlobe is behind the frontal lobe and is separated from it by the central sulcus.
The correct answer is the G2 phase. The G2 phase is usually the shortest of the three phases pf interphase. During G2 phase, many of the organelles and molecules required for cell division are produced. When the G2 phase is completed, the cell is ready to enter Mitosis and begin cell division. Hopes this helps!

Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
