Answer: See explanation

Explanation:

It should be noted that protein consist of amino acids. There are hundred of amino acids that are contained in protein. Examples of protein include fish, meat, eggs, nuts etc.

The amino acid sequence that can be found in the protein determines the primary structure of protein. The functions of protein include building and repair of body tissues, it also helps in maintain a proper potential of hydrogen (PH) for the body. Lastly, protein is also essential for growth as they help in cell and tissue growth.

Enzymes are catalysts that are responsible for speeding the chemical reaction rate in the body cells. Enzymes help in digestion.

Hemoglobin, is a protein that contains iron that can be found in the blood of animals. The function of the haemoglobin is to help in transferring oxygen to the tissues from the lungs.

There are two properties that affect the conduction speed of an action potential along an axon: die axon's diameter and whether
Rom4ik [11]

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

12. How can water move from one tracheid into a neighboring cell?
olganol [36]

Answer and Explanation:

12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.

13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.
