"Mechanical Energy is the energy of motion of an object"
Hope this helps!
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
Answer:
Visceral peritoneum is correct
Explanation:
Answer:
At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.
Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
Answer:
c) 3'-UGUGUGUGUGUGUGUG..-5
a) 3'-GUGUGUGUGUGUGUGU...-5
Explanation:
As you may already know, RNA is a single stranded molecule, unlike DNa which is a double stranded molecule. You should also already know that RNA is synthesized from one of the DNA strands, in a process called genetic transcription.
It is important to note that the ends of the DNA strands have "names", one end is called 5 'while the other end is called 3'. In DNA, the 5 'end of one is paired with the 3' end of the other strand. Both DNA and RNA are synthesized in the 5 '------> 3' direction of DNA. In the case of the RNA molecule, this means that the molecule synthesizes will have the ends of its strand formed in the 3 '----> 5' direction.
Accordingly, if an RNA strand is synthesized with a UG dinucleotide sequence, that strand may have the following orientations:
- 3'-UGUGUGUGUGUGUGUG..-5
- 3'-GUGUGUGUGUGUGUGU...-5
