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.

Inga [223]

Answer:

I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.

Explanation:

Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.

A single motor neuron together with all the skeletal muscle fibers it innervates is called a _____.
mylen [45]

A single motor neuron together with all the skeletal muscle fibers it innervates is called a motor unit.

  • Motor neurons are more than just relays for the motor commands sent down the hierarchy from higher levels. They themselves are parts of intricate circuits that carry out extensive information processing.
  • Due to their highly branching, intricate dendritic trees, motor neurons are able to integrate inputs from several other neurons and generate accurate outputs.
  • A single motor neuron, and nothing else, innervates each and every muscle fiber (make sure you understand the difference between a muscle and a muscle fiber). However, several muscle fibers can be innervated by a single motor neuron.
  • A motor unit is the aggregate of a single motor neuron and all of the muscle fibers that it innervates. The innervation ratio refers to how many fibers a motor unit innervates.
