Answer:
A presynaptic neuron knows when and how much of a certain neurotransmitter it has to release into the synapse by the frequency of the action potential.
Explanation:
Two nuerons connect to each other through synapse. When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane, then the calcium which is present in hi highconcentration outside the neuron than inside, rushes into the cell. The Calcium then allows synaptic vesicles to fuse with the axon terminal membrane, releasing neurotransmitter into the synaptic cleft.
The nuerotransmitter than binds to the receptors at the post-synaptic cleft and causes the opening or closing of the channels, hence, depolarizing or hyperpolarizing the cells.This can produce a change in the membrane potential—voltage across the membrane of the receiving cell.
<span>AUTOTROPH 1. an organism that can make its own food
Plants like algae are autotrophs. They produce their own food with the use of light, carbon dioxide, water, and other chemicals that are vital in their food producing activity. Aside from plants, there are autotroph organisms. An example of this is phytoplanktons.
CALVIN CYCLE 2. the dark reaction process of photosynthesis that uses carbon dioxide for the synthesis of carbohydrates
The Calvin Cycle has three phases. These are 1) carbon fixation, 2) reduction reactions, and 3) RuBP regeneration.
This cycle occurs in the stroma of the chloroplast and it converts carbon dioxide and other chemical compounds into glucose.
CAROTENOID PIGMENT 3. a pigment ranging in color from yellow to red; helpful in capturing the Sun's light energy for use in photosynthesis
Carotenoid is a plant pigment. It produces yellow, orange, and red colors of many fruits and vegetables. Carotenoid pigment is identified as a class of phytonutrients that benefits human health. People who consumes carotenoid rich fruits and vegetables enjoys the antioxidant property of the food as well as the Vitamin A that some carotenoid convert into.
CHLOROPHYLL 4. a green pigment in plants that serves to trap the Sun's energy for photosynthesis
Chlorophyll is the combination of two Greek words "chloros" and "phyllon" which means green and leaf respectively. This pigment also contributes to human wellness as consumption of plants rich in chlorophyll are proven to be very healthy. These health benefits are 1) helps fight cancer, 2) improves liver detoxification, 3) speeds up the healing of wounds, 4) improves digestion and helps control weight, and 5) protects skin from skin virus like cold sores.
CHLOROPLAST 5. the tiny body that contains chlorophyll; part of the cell in which photosynthesis takes place
Chloroplast is a type of plastid that can be distinguished from other plastids due to its green color. Chloroplast is the only plastid that contains chlorophylls a and b, thus its green color.
PHOTOSYNTHESIS 6. a process that involves the use of carbon dioxide and water in the production of glucose and oxygen using the Sun's energy
RADIATION 7. transfer of heat or energy through rays of various wavelengths
</span><span>Radiation is defined as energy travelling through space. Sunshine or sunlight is an example of radiation. Its ultra violet rays radiates heat on the earths' surface which in turn helps our autotrophs undergo photosynthesis.

Answer:
The Golgi complex is compromised
Explanation:
The Golgi complex helps in the process of synthesis and packaging of proteins and lipids, especially those proteins that are for exportation. The organelle´s function is to manage the recently synthesized proteins, to transform them, and to export them to other places.
Different proteins are synthesized in the endoplasmic reticulum and sent to the Golgi complex in vesicles, where it happens the final association of carbohydrates with proteins. Finally, protein is transported from the Golgi complex to its final destiny. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
By being affected by the achondrogenesis 1a, the Golgi complex loses its functions and is incapable of finishing the protein synthesis and transport process, affecting other cells and their functions.
Answer:
Sequence of amino acids by the ribosome are the characteristic of a protein may change during a DNA mutation. Explanation: Point mutations can cause significant changes to an organism if they alter the way a protein functions. A mutation in DNA changes the mRNA, which in turn will change the amino acid chain.......
