Answer:
ligand; ions; ligand; ions; nervous system
Explanation:
Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.
The answer would be "C" the because it does not do photosynthesis, It does cellular resporation. (It is not a plant)
Answer:
True
Explanation:
When we talk about fossils, we are referring to the remains of organisms that had once lived. These are traces of the organisms that existed in the distant past.
These fossil records help us to reconstruct plant and animal life in the past as well as their evolutionary processes, which can be either slow or rapid.
Fossil records reveal extinct species and help us to make sense of the evolutionary processes on earth.
A cladogram is a branching diagram that shows the cladistic relationship between a number species. It comes from the greek clados meaning branch and gramma meaning character. It is not to be confused with an evolutionary tree since it does not show the relationship between ancestors and descendants plus it also lacks the ability to show how they have changed over time. The major components of a cladogram are the tip (the start of the lineage), root (the end of the lineage) and node (where two or more lineages combine).
6-C (breaks off)
7-C(they secrete acid that breaks away rocks)
