Among the given name of the equinoxes, the fall equinox and the spring equinox are the valid names for the equinoxes.
The fall equinox, or the autumn equinox is the September equinox, while the spring equinox, which is also known as the vernal equinox is the March equinox.
There are no such equinoxes as partial or total equinox.
Hence, the correct answer is option A and D.
Answer:
<em>D</em><em>)</em><em> </em><em>A-</em><em> </em><em>Proton</em><em> </em><em>,</em><em> </em><em>B</em><em>=</em><em> </em><em>Electron</em><em> </em><em>,</em><em> </em><em>C</em><em>=</em><em> </em><em>Neutron</em><em> </em><em>and</em><em> </em><em>D</em><em>=</em><em> </em><em>Nucleus</em>
Explanation:
1.Electrons orbit the nucleus
2. Protons and neutrons are contained inside the nucleus
Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin a protein that carries oxygen in red blood cells. People with two copies of the sickle cell gene have the disease.
Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
