Answer: The number of observations (sample size) is important in determining the reliability of statistical inferences. The kind of observations depends on what hypothesis is being tested. Different statistical techniques are required depending on whether the data is categorical or discrete or continuous and whether observations are quantitative or qualitative. Increasing the kinds of observations (multiple sets of data) may also add to the reliability of the test of the hypothesis.
Explanation:
In general, a larger sample size improves the reliability of any statistical inference, particularly when there is more variability (higher variance) in the data and when the expected effect is small. A larger sample reduces the chance of random error.
Where more than one variable is associated with output data, it is of course necessary to collect data of different kinds. For example, if your hypothesis is:
H: y = ax1 + bx2 + cx3 + ...........
then you need to have observations of x1, x2, x3.........

Explanation:
The peripheral nervous system is responsible for sensory reception and
motor responses. This requires fast action potential transmission. These
impulses will travel through
A white matter and is unmyelinated
B. white matter and is myelinated
C grey matter and is unmyelinated
D. grey matter and is myelinated
Answer:
B. white matter and is myelinated
Explanation:
white matter contains Axons. Impulses travel through axons. A myelinated axon transmits action potentials at a speed of about 100m/s while a unmyelinated axon transmits action potentials at a speed of about 1-10m/s
The grey matter contains the cell bodies of neurons

Answer:
A population of mice occupies a tree stump in a forest. During the last decade, there has been little change in the number of mice in the population. Which of the following would likely cause the number of mice to decrease quickly?
Explanation:
According to the scenario, the time of the next high tide would be 8:30 p.m. Thus, the correct option for this question is C.
What is High tide?High tide may be defined as the tide when the water is at its greatest elevation from the ground level. The tide gets significantly high when the sea or ocean is closer to the Moon. It disturbs the life of all sorts of aquatic animals.
According to the context of this question,
The time at which an observer recorded the first high tide = 7:12 a.m.
The time at which an observer recorded the second high tide = 7:38 pm.
The time at which an observer recorded the third high tide = 8:04 a.m.
So, the difference between the time of all these tides is found to be 12 hours and 26 minutes.
Therefore, the next and fourth high tides would be observed after 12 hours and 26 minutes at 8:04 a.m which is 8:30 p.m.
Therefore, the time of the next high tide would be 8:30 p.m. Thus, the correct option for this question is C.

B)The tropical rainforest receives the most rain.
C)The tropical rainforest is much warmer than the savanna.
D)The woodland receives less rain than the temperate forest.
E) The subtropical desert receives more rain than the tundra.
Answer:
A and B
Explanation:
also D is not one because Temperate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive heavy rainfall. ... The moist conditions of temperate rain forests generally support an understory of mosses, ferns and some shrubs and berries.
Statements that are supported are the option "A" and "B" that is the tundra is cold and dry and the tropical rainforest receives the most rain.
What is a biome?The meaning of a biome is a restricted or global land space that is described by the flora, fauna and environment of that area.
An example of a biome is a desert that has flora and fauna that live successfully with intense warmth and smaller no rain.
Thus, the option "A" and "B" that is the tundra is cold and dry and the tropical rainforest receives the most rain.

Explanation:
If two objects have the exact same volume and they both sink, but one has more mass than the other, will they displace the same volume of water? Explain your answer:
Answer:
No.
Explanation:
No, they will not displace the same volume of water because both objects has same volume. The volume of water displaces if the volume of an object is increases while more mass has no effect on the volume of water. So if we put the two objects in water having same volume so it will not displace the volume of water if mass is increased.

Most sex-linked Gene's are on the ____ chromosome, simply because they are built of much more DNA. However, _____ are more likely than _____ to exhibit sex-linked traits.
Answer: most sex-linked genes are on the X chromosomes because they are larger than Y chromosomes. Males are more likely than females to exhibit sex-linked traits
Explanation:
Males are more likely than females to display recessive traits because a single recessive gene on the X chromosome is often not matched by a Y chromosome allele and therefore expressed.

How do the cells in your kneecap get rid of the waste product of cellular
respiration?*
Answer:
Please find the explanation to how cells in the kneecap get rid of waste products of respiration.
Explanation:
Cellular respiration is the process by which glucose molecule is broken down to release energy in form of ATP. The major waste product of this process of respiration, however, is Carbon dioxide (CO2).
Since all cells in a living organism like human, whether kneecap cells or brain cells, undergo respiration, CO2 is excreted out of all cells via DIFFUSION i.e the CO2 molecules move out of the cell where it is in high concentration into the bloodstream, where it is in low concentration via the cell membrane. The blood transports the CO2 waste to the alveoli of the lungs, where it is finally exhaled out of the body.

Which statement best describes what Earth’s outer layer is like underneath the surface in the image?
A. Underneath the soil, Earth's outer layer is made of water.
B. Underneath the soil, Earth’s outer layer is made of hard, solid rock. Underneath the ocean, Earth’s outer layer is made of sand.
C. Underneath both the soil and the ocean, Earth's outer layer is made of hard, solid rock.
D. Underneath both the soil and the ocean, Earth's outer layer is made of sand and water.
Answer:
My guess would be C
Explanation:
The crust, which is Earths outer solid layer of rock, is around 20km thick if I remembered correctly, and the ocean is nowhere near that, so there would be rock under the ocean.
If you find a better answer, then use it, because I'm not completely sure, but that's my best guess based on the possible answers
The crust of the earth is a thin, solid, layer of rock
Your answer is C.
