C) is correct because light energy is converted into glucose in the process of photosynthesis.Also the air we breath in aka oxygen is exhaled as carbon dioxide which plants convert. into oxygen.Products of photosynthesis are the reactants of cellular resperation.
Answer;
Kingdom plantae.
Explanation;
Kingdom plantae is a classification kingdom made up of eukaryotic, multicellular organisms that have cell walls made mostly of cellulose.
They have pigments (chlorophyll) that absorb light, and that supply energy and oxygen to themselves and to other life-forms through photosynthesis
They are Eukaryotes, multicellular, autrotrophs, and have cell walls are made of cellulose, and are also producers in an ecosystem.
Since fire is a chemical reaction, and oxygen is needed for that reaction, having a fire in a cave is a sure sign of the presence of oxygen.
<span>Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.<span>

Answer:
(3) Synaptic vesicles release neurotransmitters via exocytosis.
(4) Neurotransmitters diffuse across synaptic cleft.
(1) The neurotransmitters bind to receptors on the postsynaptic cell.
(2) The postsynaptic cell is stimulated to initiate a nerve signal.
Explanation:
Neurons transmit nervous impulses. These cells connect to each other by the process of synapsis. Neurons are composed of the cellular body, dendrites, and the axon that conducts the electrochemical signals. As it occurs in every synapsis the presynaptic neuron sends information to the postsynaptic one. Vesicles carrying the neurotransmitter fuse with the presynaptic membrane and release the molecule by exocytosis to the intercellular space. This chemical substance travels through the synaptic cleft to the junctional area of the other neuron and binds to its receptors in the postsynaptic membrane. This binding produces depolarization of the cell. An action potential is initiated and spreads to the rest of the membrane depolarizing it.
