Answer: It appears compartmentalized under the microscope.
Explanation:
All living organisms are made up of cells. And cells grow by undergoing cell division.
Also, when viewed under the microscope, cells appear as 'rooms' or 'compartments'
Thus, the growing substance is living and contains cells
Biological Weathering<span>Biological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things called </span>lichens<span> (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler. </span>

C) acetylcholine
Explanation:
Acetylcholine is an excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle.
However, norepinephrine, gamma aminobutyric acid, and cholinesterase are not excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle.
For the answer to the question above, I believe the answer is the<span> phylogenetic species concept</span>.
The key to the phylogenetic species concept is that species must be "diagnosable." In other words, members of the species should share a combination of characteristics that other species don't have. To look for some unique features that define a phylogenetic species, systematic comparisons must be done by paleontologists with other related fossils or living species
