The correct answer for this question is "B. dicotyledonous plant." Alice is examining the transverse section of a stem under the microscope. She observes that the vascular bundles are arranged in a concentric pattern.The type of plant is she looking at is a <span>dicotyledonous plant.</span>
Answer: B. They always have offspring identical to the parent plant.
Answer:
<em>B. Methyl yellow, which changes from yellow to red around a pH of
</em>
<em>4.0</em>
Explanation:
A pH indicator is a technique by which the pH of a solution can be known. The scenario in the question describes that the scientist wants to determine a pH after it gets converted from 6 to below 4. For this recognition, the scientist should use a methyl yellow indicator which will change from yellow to red once a pH around 4 is achieved.

Answer:
The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.
Explanation:
In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.
