Out of the following given choices;
A) excitatory, but not inhibitory, synapses
B) inhibitory, but not excitatory, synapses
C) electrical synapses
D) ligand-gated ion channels
The answer is D. These are transmembrane ion-channel proteins that open to allow ions such as Na, K, Ca, and/or Cl to pass through the membrane in response to the binding of a chemical messenger (i.e. a ligand), such as a neurotransmitter.
Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat.
I think you just typed the answer in the 2nd paragraph:)
Rhizomes are involved in the production of stems and “reproduction” of new plant parts. It has been theorized that rhizomes, when removed, can grow into completely new (but genetically identical) plants! It’s kind of like budding, so it’s pretty cool.
I hope I helped!
