Answer:
The student forgot to add reverse transcriptase
Explanation:
Reverse transcriptase is an enzyme, also called DNA polymerase or RNA-dependent, responsible for carrying out the transcription process, which corresponds to an “inverted copy”, as opposed to the cellular pattern. In other words, this enzyme polymerizes DNA molecules from RNA molecules, the opposite of what commonly occurs in cells.
The student, exposed in the question, wanted to create cDNA through an isolated and amplified mRNA sample, but this student did not use reverse transcriptase, so it would be impossible for his experiment to have good results.
Answer:
A. Increased Speed
Explanation:
stretching can't affect your speed, instead it enhances flexibility, helps you preform perform activities more efficiently and you will have a better range of motion.
<span>B. Regular physical activity can help with energy levels, can improve self-image (and, thereby, school attendance), but it will not decrease a person's attention span. If anything, the person will increase their span because of the focus required to perform the activity to an acceptable level.</span>
Answer:
Explanation:
Hyperglycemia (high blood sugar) may occur when too many sugars are consumed. It's made worse if there's inefficient or insufficient insulin to transport sugars to the cells for energy. Sugars are the cells' main source of energy, which explains why inefficient or insufficient insulin may leave you feeling tired
