Answer:
Explained below
Explanation:
Human body is made of chemicals. There are thousands of metabolic reactions occurring simultaneously inside our body. The sum total of all the chemical reactions in our body is called metabolism that involves catabolism and anabolism. A catabolic reaction is state that the breakdown of food to obtain energy and anabolic reaction uses this energy to synthesize larger molecule from smaller molecule. These reactions are critical for maintaining life.
Answer:
Golgi bodies
Explanation:
This is the organelle that is responsible for the packaging and sending of needed nutrients in and out of the cell through the cell membrane
The chromosome - together with ribosomes and proteins associated with gene expression - is located in a region of the cell cytoplasm known as the nucleoid.
Hope this helps
Answer:
Axons with high diameter, and myelinated will conduct action potential faster.
Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission
Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.
Axons with low diameter, and unmyelinated will conduct action potential slowly .
Explanation:
Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.
Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1
.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
