a. the production of bubbles by the plant when it is in darkness
Explanation:
The indirect observation that will show that the gas produced in this experiment is oxygen is by observing the bubbles on the surface of water in darkness.
Oxygen gas is a by product of photosynthesis. Photosynthesis occurs in the dark and when there is light.
If we observed the bubbles over water, it shows that oxygen gas is given off and the water plant is photosynthesizing. This is a good way to observe the oxygen gas indirectly.

The ion which is entering axon terminal A is called Ca²⁺.
The effect which it has is, it causes the release of neurotransmitter from the axon terminal.
Axon terminal is termed as distal termination of telodendria of an axon. Another name for the axon terminal is synaptic boutons. Axon is a long, slender projection which is of a nerve cell.
Their work is to conduct electrical impulses which are referred to as action potential which is a way of neurons of the cell body. Neurons use electrochemical signals and also a neurotransmitter chemical which transmits impulses from one neuron to another.
Axon terminals are being separated from neighboring neurons by a gap known as a synapse. Both the axon terminal and neuron they come from a point which is called the presynaptic neuron.
<span>Chemical reactions occur when different atoms and molecules combine together and spit apart. For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs.So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atoms are rearranged as bonds are broken and formed. In all chemical reactions, mass is always conserved...In chemical reactions, atoms rearrange to form products. Hope I helped!</span>
Answer:
145 degrees
Explanation:
Because the united states food and drug administration recommends cooking salmon to an internal temperature of 145 degrees Fahrenheit. Push the tip of the meat thermometer gently into the middle of the salmon fillet at its thickest part.
