Answer:
To conclude, you cannot prove a hypothesis because you can never generalise the results to the whole population and foresee the results will always be the same in the future. You can however, reject the null hypothesis consistently, through statistical hypothesis testing so that the theory becomes highly likely to be true, but not proven.
Explanation:
A lunar eclipse happens when the Moon passes directly behind the Earth and into its shadow. This can only happen when the Sun, Earth, and Moon are aligned. Because of this, a lunar eclipse can only happen on the night of a full moon.
The moon gives off a reddish appearance during this time because the only light reaching the moon and reflected off of its surface is the light refracted by the Earth's atmosphere (the same reason a sunrise/sunset appears reddish).
A totally eclipsed full moon is also known as a Blood Moon because of it's colour

You would find layers in a sedimentary rock, because it has different types of other rock combined in it.
<u>The offspring are genetically unique. </u>
Answer: Option C
<u>Explanation:</u>
Meiosis is a form of cell division that is concentrated towards the reproductive cells. In this cell division the diploid cells (two sets of chromosomes) undergo reduction to form a haploid cell (one set of chromosome). The haploid cell produces sperms and eggs.
Meiosis occurs in two levels Meiosis I and II. Chromosomal segregation happens during meiosis I and II to produce a genetic diversity. The important net result obtained by the meiosis is to produce a genetically unique offspring.
The question is incomplete as the image and options are not given, however, the correct image and options are as follows:
A. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will increase.
B. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will decrease.
C. When the temperature of gaseous Material A increases, its volume will increase.
D. When the temperature of liquid Material A increases, its volume will increase.
Answer:
The correct answer is - C. When the temperature of gaseous Material A increases, its volume will increase.
Explanation:
The figure and table related to the given question are attached with the answer that shows the volume change during the time period in relation to temperature and the phase of material also changes with an increase in temperature.
According to Figure 1, it is clear that initially, Material A was in the liquid phase and after a certain temperature, it is constant at a phase of a mix of liquid-gas and finally entirely in the gas phase from Time 22 sec to Time 24 sec. as temperature increased and the volume of Material A also increased according to the table 1.
So the hypothesis C is correct.
