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.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
My name is Ann [436]

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.

How is a generic embryonic cell different from a differentiated cell?
Rom4ik [11]

A generic embryonic cell is different from a differentiated cell because it has a specific structure to perform a certain function. During development, cells become increasingly different from one another so that they can be specialized for specific functions.

<h3>What are embryonic cells?</h3>

These stem cells come from embryos that are 3 to 5 days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

With this information, we can conclude that Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

I believe the answer would be A, because if water didn’t exist, there would be no presence of living things on earth. Water is a resource for life, thus, presence of living things.

Explain why bacterial cellsouter memarane ruptures when the cells
qwelly [4]

Answer and Explanation:

When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall.

The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.
