Answer:
c. Two sister chromatids did not separate into the proper daughter cells during anaphase.
Explanation:
The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.
However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).
Answer:
The TATA box helps bind the <em>RNA polymerase</em> in the correct place.
Explanation:
The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.
The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.

d. all of the above
Explanation:
The diencephalon is a part of the brain located inferiorly and anteriorly to the corpus callosum, part of the telencephalon, and superior to the midbrain, delimited by the latter by an imaginary line that runs from the nipple to the posterior commissure (epithalamus). The diencephalon consists of: thalamus, hypothalamus, epithalamus, metatalamus and subthalamus. For this reason, we can conclude that the correct answer to your question is "d. All of the above".
Answer:
C
Explanation:
There are several cells, therefore it is multicellular. They also have nuclei, meaning that this organism is a <em>multicellular eukaryote.</em>
