Answer:
X in the diagram represents the cell membrane and performs the function of regulates the transport of materials.
Explanation:
The cell membrane, marked with X in the diagram, is a lipid bilayer with hydrophobic properties, which acts as a semi-permeable membrane to the passage of substances.
This membrane, that covers the cell and keeps it isolated from the extracellular space, has the function of controlling or regulating the passage of materials from the extracellular to the intracellular space, as well as the exit of substances from the interior of the cell. To fulfill this function it has several alternatives of transmembrane transport.
The other options are not correct because:
- <em>The cell membrane does not </em><em><u>control the energy released</u></em><em>.
</em>
- <em><u>Protein synthesis</u></em><em> occurs in the rugged endoplasmic reticulum.
</em>
- <em><u>Cellulose synthesis</u></em><em> occurs inside the cell, a process dependent on photosynthesis.</em>
The idea that atoms move around definite pathways around the nucleus was coined by Neils Bohr in 1913. he postulated that electrons in the atom will absorb energy and move up to higher orbitals. when the electrons give off energy they go back down to lower orbitals. he postulated that this lose of energy was visible light.
hope this helps (:

Answer:
Explanation:
The layer most likely to have organisms which lived at the same time as the bird species is Layer 2. Layer 2 is closer to layer 3 than any of the other layers listed. Assuming that layers were laid down sequentially as time passed, it is reasonable to assume that layer 2 was laid down most closely in time to layer 3.
