Answer:
1. Message; chemical; transduced; actions.
2. Protein modification; phosphorylation cascade; energy.
3. Signal Transduction Pathways (STP).
Explanation:
Transduction can be defined as a process which typically involves the change of a signal message contained in the outside of a cell to a message within or inside the cell.
1. Signal Transduction Pathways start with a message in the form of a chemical message that is transduced into actions within the cell.
2. The two types of Signal Transduction Pathways (STP):
a. Protein modification.
b. Phosphorylation cascade: a phosphate that has energy is passed from one chemical to another until it eventually has an action.
3. An example with G-Protein in the Liver: is a signal transduction pathway (STP).
a. Messenger: docks with the receptor, specifically the G protein receptor.
Answer:
i think its d....not sure
The right answer is C. Level 1 (bottom).
Ecological pyramids occur in their basic producers (such as plants) and follow a sequence of several trophic levels (such as herbivores that eat plants, carnivores that eat herbivores, followed by carnivores that eat carnivores, And so on). The highest level is the top of the food chain leads to superpreders.
<h2>Neural crest </h2>
Explanation:
The neural crest likely forms: neurons and glia of the peripheral nervous system
- The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
- In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
- The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
- Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
- Glia are also essential to nervous system function, but they work mostly by supporting the neurons
<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

</span><span>The aim of the pyramid is to recommend ideal rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>
