Answer:
sarcomeres
Explanation: A contracting skeletal muscle fiber typically shortens as all of its sarcomeres do this.... Thick and thin protein filaments in sarcomeres interact to cause.... True or false, thick and thin filaments maintain their same length whether the muscle is relaxed or contracted?
Answer:
Think about it. Worms move with MUSCLES. So the first answer is None.
The appendage of a roundworm is not present.
How do you think worms turn and move? They are segmented. The symmetry of a worm is Bilateral.
Explanation:
I'm doing the assignment myself. Look up the answers and use common logic.
B. Using fewer fossil fuels, such as gasoline for a car, reduces the emission of harmful pollutants into the air
Your answer would be photosynthesis because photosynthesis synthesis carbon based energy molecules from chloroplast inside a cell, with the outer membrance.
hope i helped my fellow brainily user :)
Answer:
a. positive; negative
Explanation:
Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.
The transcription process is divided into three steps: initiation, stretching and termination
During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.
During this process, it is believed that positive supercoils are generated ahead of the transcription bubble and and the negative supercoils behind it.
