Answer:
The way that plants create food using sunlight
Explanation:
Answer:
c) degree of myelination of the axon
Explanation:
Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.
Factors that determines the rate of conduction velocity are:
- axon diameter-larger diameter axons have a higher conduction velocity
- sheeth-a myelin sheath increases the rate of impulse propagatio
Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
Answer:
C
Explanation:
Add radio labeled actin sub units to a mixture of actin filaments in which conditions are favorable for polymerization. This would enable you to identify the plus end of actin filaments.
Actin filaments are linear polymer of globular actin sub units Actin filaments have polarity. This means that the two ends can be identified due to structural differences.
Polyribosomes are groups of ribosomes linearly arranged, associated with mRNA, and producing several copies of proteins. The coupling of processes shown in the image can not be found in eukaryotic cells.
<h3>
What is a polyribosome?</h3>
A polyribosome is a group of single ribosomes associated with an mRNA molecule and producing simultaneous translation events of the same protein.
Polyribosomes can be found in both prokaryotic and eukaryotic cells. However, translation occurs at different moments and places in these cells.
⇒ In a prokaryotic cell
Polyribosomes can act before transcriptional termination occurs.
While transcription is still happening, ribosomes can produce many polypeptide copies.
This is because
- both transcription and translation occur in the cytoplasm simultaneously.
- transcription and translation directions are 5' to 3'.
- mRNA does not need to be modified after transcription.
⇒ In eukaryotic cells
Polyribosomes are found in the cytoplasm but only when
- the transcription process is over,
- the mRNA molecule is already modified and left the nucleus.
Since transcription occurs in the nucleus and translation in the cytoplasm, they can not be simultaneous.
According to this information, the coupling of processes shown in the image can not be found in eukaryotic cells.
