Answer:
d. RNA polymerase II.
Explanation:
The main enzyme responsible for RNA synthesis is RNA polymerase, which <em>catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) </em>directed by a DNA mold.
Eukaryotic cells contain <u>three types of nuclear RNA polymerases</u> that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.
Answer:
False
Explanation:
Concrete steps are those steps for which full explanation details of implementation is mentioned while abstract steps are those for which some details are not mentioned or specified.
functional decomposition is referred to as the technique to developed software. In functional decomposition, in which error is divided into smaller form and solution to each smaller error then combine to give the solution to the whole error.
Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
Explanation:
When blood pressure drops too low, the rate of baroreceptor firing decreases. This will trigger an increase in sympathetic stimulation of the heart, causing cardiac output to increase.
<span>The filament of a flagellum rotates in a kind of sinusoidal motion, resembling a ship’s propeller or a corkscrew. Since the flagellum pushes instead of pulls, it is located at the rear of the microorganism. If there is more than one, they may act as a bundle. The direction of rotation determines the path of the microorganism. Flagella also serve as sensors, particularly for the detection of moisture.</span>
