Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Answer:
1)All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Atoms come together to form molecules, which are the building blocks for all types of matter, according to Washington State University
2)Energy is in everything that we eat, consume, or use. Energy fuels and regulates the body's natural internal functions. It repairs cells and body tissue, is used to build muscle, and is necessary to maintain homeostasis — and the harsher the environment, the more energy is needed to maintain

Answer:
Myelin sheath
Explanation:
Myelin sheath is a protective covering in axons that consist of lipids and proteins, produced by oligodendrocytes. This covering protects the nerve cells from receiving any other electrical impulses not directed to them. It also effeciently speeds the transmission of nerve messages amongst nerve cells in the nervous system.

Question: When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as which part of the signal pathway?
A) relay molecule
B) transducer
C) signal molecule
D) response molecule
Answer:
C) signal molecule
Explanation:
Signaling cells produce specific chemicals or compounds called signaling molecules. These signaling molecules arrive at their target cells and bind to the cell surface or intracellular receptors. Binding of the signaling molecules to their receptors present on the target cells is followed by signal transduction and production of desired response by the target cells.
Neurotransmitters serve as signal molecules that bind to the receptors present on the membranes of the postsynaptic neurons to bring about changes in the membrane potential. Their binding may trigger the opening of the gated ion channels resulting in a change in the membrane potential followed by generation of inhibitory or excitatory responses.
