The nucleotide sequence on a section of
DNA where transcription begins is called a promoter. 
 
To add, i genetics, a promoter is a region
of DNA that initiates transcription of a particular gene. Promoters are found along
the transcription beginning sites of genes, on the same strand and upstream on
the <span>DNA.</span>
 
        
             
        
        
        
Answer:
Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids. You may see books that say there are only 20 amino acids.

Answer:
adrenal
Explanation:
The adrenal glands are two endocrine glands in the human body. They are located above the kidneys.  Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.
These glands are also responsible for the production of hormones that act on the transformation of fat into glucose by the liver. An example of this hormone is glucocorticoid known as cortisol, which also acts on the degradation of triglycerides. These functions are also performed by the region of the adrenal cortex.
The adrenal glands also produce in the adrenal medulla two other important hormones: adrenaline (also known as epinephrine) and norepinephrine (also known as norepinephrine). These two hormones act on psychic and physical reactions generated by strong emotional situations (mainly related to emotional stress).
 
        
             
        
        
        
Answer:
<h2>
Question no 4 answer</h2>
Fossil fuels will still provide 60% of energy in 2040, compared to 85% today, but the pattern of use will change, away from coal and towards gas, and increasingly concentrated in industry. Fossil fuel prices would be lower in a 2˚C scenario, with less need to mobilise high-cost reserves to meet demands.
<h2>
Question no 3 answer</h2>
Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions
<h2>
Question no 2 answer</h2>
The premise of this Viewpoint article is that the sustainability of the electricity supply is very often addressed in narrow frames of reference, which sets up incremental decision-making. To more fairly compare the economic, social, and environmental aspects of renewables, such as photovoltaics, to fossil fuels, a broader view is required which needs to take into account the impacts of the fossil fuel supply chain.
<h2>
Question no 1 answer</h2>
These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world's energy. They provide electricity, heat, and transportation, while also feeding the processes that make a huge range of products, from steel to plastics.
