The T tubules store Ca2 . provide a means of rapidly transmitting the action potential from the surface into the central portion

snow_tiger [21]

Answer:

provide a means of rapidly transmitting the action potential from the surface into the central portions of the muscle fiber

Explanation:

T-tubules or Transverse tubules are the tube-like structures present in the muscle fibers.

The T tubules are formed by the modification in the plasma membrane of the cell and therefore arise from the surface of the muscle cell. The T tubules then pass through the muscle and enter the inner core of the muscle that is near to the sarcoplasmic reticulum.

The main function of the T tubules is to carry forward the action potential from the synaptic junction to the muscle where it triggers the release of the calcium from the muscle.

Thus, the selected option is correct.

Explain how you could determine wheater seeds in packets of round pea seeds have a genotype rr or rr

mezya [45]

I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!

________ is the process of breaking down decisions into smaller parts.

gregori [183]

Analysis.
The word analysis come from Greek and means dissolution, to spread.
Analysis is the process of turning a decision, a process, an issue, a substance, a topic, that maybe complex, into more simple parts so it is easier to understand whatever it is being analysed.
