Answer:
It is neither accurate nor precise.
Explanation:
<em>The data set is neither accurate nor precise.</em>
Accuracy is defined as the closeness of a measurement to the true value.
Now let us look at the average of the data set:
30 + 17 + 27 + 21 + 32 = 127/5 = 25.4
<u>The average of the data set is 25.4, whereas the correct value provided is 25. The difference between the average of the data set and the correct value is 0.4 which is beyond the margin of error allowed in measurement. Hence, the measured data is not accurate.</u>
Also, precision is defined as the closeness of repeated measurement to one another.
<u>From the data set, the individual values are not close to one another in any form and the difference between them are more than the margin of error allowed in measurements. Hence, the data is far from being precise.</u>
Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.
Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?
Answer:
"The two students who have two fragments have one restriction site in this region."
Explanation:
A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.
Answer:
A função do citoplasma é fornecer sustentação esquelética para a célula através da estrutura composta por filamentos e túbulos proteicos. Além disso, todo o conjunto de estruturas mergulhadas no citosol apresenta bastante dinamismo, fato que possibilita à célula realizar alguns movimentos.
No citoplasma, ainda há membranas que atuam como verdadeiras usinas intracelulares, que fornecem energia indispensável à manutenção da vida.
Outro fato que você deveria saber sobre o citoplasma é que ele preenche todo o interior das células eucariontes, sendo delimitado pela membrana plasmática. Já nas células procariontes, o citoplasma fica entre a membrana plasmática e o núcleo da célula.
Explanation:
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
