Answer:
The correct options are (c) and (d).
Explanation:
The assumptions made before using a <em>t</em>-distribution for a hypothesis test are:
- The scale of the data should be continuous or ordinal.
- The sample selected should be a simple random sample.
- The data selected should follow a normal distribution or form a bell-shaped curve when plotted.
- The sample selected must be large enough so that when plotted a normal distribution curve is formed.
- Homogeneous variance exists so that the standard deviations of the samples are approximately equal.
A sample size of 5 a sample size of 50 sample will not be accurate for a <em>t</em>-test because on of the sample size is, 5.
This sample size is very small and when plotted will not follow a normal distribution.
The sets that differed in variance will not be accurate for a <em>t</em>-test because for using a <em>t</em>-test homogeneity of variances is assumed.
Thus, the correct options are (c) and (d).
The answer is D. The Nucleus houses DNA. Please give me brainiest! ;)
Answer:
they amplify the original signal manyfold.
Explanation:
A phosphorylation cascade can be described or is regarded as a sequence of events, where one enzyme phosphorylates another, causing a chain reaction, leading to the phosphorylation of thousands of other proteins.
Phosphorylation cascades is considered to be important because it plays a vital role in regulating many intra cellular processes such as growth, proliferation and cell division.
In conclusion , it should be understood that, cells make use of phosphoylation cascades for signal transduction, bringing outside stimuli to the interior of the cell, to stimulate a response.

Answer:In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization, and metamorphism as they travel between Earth's surface and its interior layers. In the water cycle, water particles undergo evaporation, condensation, precipitation, and flow.
