Im pretty sure your answer is b.
If you mean reliability for say an experiment.
1. Detailed procedure of the experiment should be published. How many samples were tested? List of the equipment that were used and justified explanations of the process. These are important in order to prevent things like conspiracy or oversimplified test (only using a small number of sample).
2. Experiment should be done not only by one particular expert, but lots.
If for example, Professor ‘A’ makes the hypothesis, he should not be the only one who does the experiment. Even if he has hundreds of assistant, it may not be fair, as bias may play a significant role. In order to reduce a factor called bias, other expert (with at least the same qualification) should take part in the experiment.
<span>3. </span>A wide variety of ‘sample’ (in psychology would mostly be animal, or human in some case) <span>must be tested. </span>It is important to remember that each person is unique while the world consists of 6 billion people. Therefore by testing a group from the same place or background might not be enough. Things like culture/background, physical condition or surroundings need to be put into consideration.
These 3 factors are very important in order for the word ‘reliability’ to be awarded. They will also be beneficial in terms of keeping us from having any knowledge that may lead us astray. Remember that knowledge comes from a hypothesis, and for a hypothesis to be approved; it needs to be tested first by experiments. Those 3 factors would be needed to increase reliability.
Answer:
Voyager 1 is the farthest human-made object from Earth, NASA launched it on September 5, 1977, and as of October 2019, it had traveled 13.7 billion miles from the planet. Voyager 1 is believed to have left the solar system in 2012 and is set to encounter its target star AC +79 3888 in about 40,000 years.

Answer:
E) sister chromatids separate during anaphase of meiosis I.
Explanation:
Chromosomes are composed of two chromatids which are joined together through centromere. Chromosomes get doubled its chromatids during its S phase of Interphase. Although chromosomes number remains the same as after S phase but number of chromatids becomes double.
For Example:
In humans 46 chromosomes are present before S phase and 46 chromosomes after S phase. only difference is that chromatids before S phase is 46 in number while after S phase it becomes double i.e becomes 92.
During Prophase 1 of Meiosis 1 these 46 chromosomes with 92 chromatids get arranged in manner that homologous chromosome pair comes close together and form 23 pairs.
During Metaphase 1: These 23 pairs get arranged in center and attached with spindle fiber present inside cells. Each spindle fiber attach to one member of the pair in a manner that 23 spindle fibers from one side of pole attached to one member of homologous chromosome pairs and 23 spindle fibers from other side of pole attached to other member of homologous chromosome pairs.
In Anaphase 1 of Meiosis 1 these spindle fibers get contracted and pulled attached chromosome along with them towards opposite poles. In this manner chromosome numbers in Meiosis become half as compared to the Mitosis
So Correct Answer of the question is
E. sister chromatids separate during anaphase of meiosis I.
