Explain in detail how to decide the number of replications in a simulation study. Use fixed-sample-size and sequential procedure
erik [133]

Explanation:

Fixed sample size:

In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.

Sequential procedures:

→Sequential procedures helps while we are collecting the data.

→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.

→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.

→In this two or more blocks of different sizes are prepared for testing.

→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

A student makes a claim that a cell is undergoing the process of transcription . What evidence woul
AlexFokin [52]

Question:

The complete question has these options:

A) tRNA with anticodons is carrying amino acids to the ribosomes.

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.

C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Answer:

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Explanation:

During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing

A) tRNA with anticodons is carrying amino acids to the ribosomes.  - this is not evidence of transcription but is instead evidence of translation

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.  - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.

C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins  - this is not evidence of transcription but is instead evidence of translation

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.

Which of the following peripheral nervous system (PNS) neuroglia form the myelin sheaths around larger nerve fibers in the PNS?
Scorpion4ik [409]
The part of the peripheral nervous system (PNS) neuroglia that form the myelin sheaths around larger nerve fibers in the PNS would be the Schwann cells. The most important function is to myelinate the axons found in the PNS. Myelin aids in the increase of the saltatory conduction of a neuron.

salantis [7]
Taking all of them out of their natural environments would disrupt the ecosystem and food chains, and it would be difficult, if not impossible, to place more than a small portion of Earth's endangered species in these facilities.
