Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by <em>nuclear pore complex.</em> It allows the pore to <u>regulate the movement of molecules between the nucleus and the cytoplasm.</u> It allows small particles to pass through such as ribosomal proteins. It prevents most large particles<em> (except for histone)</em> from passing through; thus, <u>it is selective in nature</u>. This function of the pores clearly shows that <em>it allows communication to occur between the nucleus interior and the cytoplasm.</em>
Answer:
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, which have no membrane-bound organelles.
Explanation:
Answer:
It is important to have a standardized system of classification so people can easily identify different things. It allows scientists to identify, name and group different organisms. It is important so scientists are able to easily communicate about different organisms without confusion.
It is necessary to classify organisms because: It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences
if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world. Instead, all organisms would be categorized differently in every part of the world, with different names.if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world.

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).
