Answer:

Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

Explanation:

Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

Which division of the ans is responsible for the physiological changes you experience when startled by a loud noise? (module 14.

Sliva [168]

Sympathetic nervous system under the Autonomic nervous system (ANS) is responsible for the physiological changes you experience when startled by a loud noise.

Autonomic nervous system (ANS) is part of the peripheral nervous system (PNS) and is responsible for control of vital functions.

ANS possesses three divisions, they are : Sympathetic nervous system (SYNS), parasympathetic nervous system and enteric plexus. Sympathetic nervous system is responsible for flight and fight responses.

SYNS also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.

The ganglions associated with SYNS mostly arise from the thoracic and lumbar regions of the spinal cord.

zhenek [66]

The correct option is (D) The ecological footprint of the United States is large because per capita resource use is high.

<h3>What is ecological footprint?</h3>

The Global Footprint Network advocates using the ecological footprint to determine how much nature is required to support a certain population or economy.
The ecological footprint accounting system tracks how much nature is being used and produced.The Ecological Footprint calculates the total productive areas for which a population, a person, or a product competes on the demand side.
It evaluates the ecological resources required by a specific population or product in order to produce the natural resources it consumes, as well as to absorb its waste, particularly carbon emissions.
The biocapacity of a city, state, or country, on the supply side, measures how productive its ecological resources are (including cropland, grazing land, forest land, fishing grounds, and built-up land).
These regions can also be used to absorb the garbage we produce, particularly our carbon emissions from burning fossil fuels, especially if they are left unharvested.
