Neurotransmitter has to be consumed in the diet is not the criteria for neurotransmitter. So the correct option is a.
A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.

The axon terminal, a component of the neuron, is where neurotransmitters are found. They are kept inside synaptic vesicles, which have thin walls. Numerous thousands of neurotransmitter molecules can fit inside each vesicle.

ionic bonding.
Ionic bonding<span> is a type of </span>chemical bond<span> that involves the </span>electrostatic attraction<span> between oppositely charged </span>ions<span>, and is the primary interaction occurring in </span>ionic compounds<span>. The ions are atoms that have gained one or more </span>electrons<span> (known as </span>anions<span>, which are negatively charged) and atoms that have lost one or more electrons (known as </span>cations<span>, which are positively charged). This transfer of electrons is known as </span>electrovalence<span> in contrast to </span>covalence<span>. In the simplest case, the cation is a </span>metal<span> atom and the anion is a </span>nonmetal<span> atom, but these ions can be of a more complex nature, e.g. molecular ions like NH</span>4+<span> or SO</span>42−<span>. In simpler words, an ionic bond is the transfer of electrons from a </span>metal<span> to a </span>non-metal<span> in order to obtain a full valence shell for both atoms.</span>
The right option is; d. Runoff describes water movement and infiltration describes water storage.
Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.
Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
Plants and other things that make food for themselves and use the sun to make food
Samuel ate some vegetable soup. <u>Digestion</u> process is at work to allow Samuel to break down the soup so that his body will be able to produce energy.
<u>Option: D</u>
<u>Explanation:</u>
There are majorly four steps in food processing in human body, these are ingestion, digestion, absorption and elimination. There are six major phases covered by digestion: ingestion, acceleration, mechanical or physical digestion, chemical digestion, absorption and defecation. The first of these procedures, ingestion, relates to the absorption of food via the mouth into the food canal.
Digestive system allow the transformation of massive insoluble food molecules into small water-soluble food components to dissolve them into the watery plasma of the blood. Many smaller particles are ingested into the bloodstream in certain species through the small intestine.
