Correct answer is option D.
Transcription activators accelerate transcription, while transcription factors assist RNA polymerase binding.
<h2><u>
</u></h2><h2><u>
Explanation</u></h2>
Transcription factors are the proteins which help in proper binding of RNA polymerases in the promoter region of DNA so as to facilitate transcription.
Activators on the other hand, help in the enhancement of the transcription rate.
Transcriptional activators are basically proteins which bind to the regulatory elements known as enhancers so as to increase the rate of transcription. Enhancers are specific DNA sequences, which may be present in the upstream or downstream region of the gene which is going to be transcribed.
It may be noted here that transcription factors are only present in eukaryotes. In prokaryotes, sigma factors are present instead of transcription factors to facilitate proper binding of RNA polymerases on the DNA.
Both kelps and coral reefs are composed of algae that grow in the shallow parts of the ocean in warm and sunny waters. However, kelp forest grows in nutrient-rich waters while corals can develop in low nutrient waters.
Kelp forests are therefore common where warm and cold current meet in an up-welling. Coral reefs are borne of a symbiotic relationship between coral polyps and algae. The coral forms a rigid carbon skeleton of calcium carbonate while kelps are long flexible algae plants.
Hey there!
Here are your answers:
<u><em>1. The proper answer to this question is "the Sun".</em></u>
Reason:
<u><em>The Sun is the ultimate source of energy for organisms it allows plants to use photosynthesis </em></u><span><u><em>to convert light energy into energy for that organisms and other organisms.</em></u>
<em>Therefore the answer is the Sun.</em>
Here is your second answer:
<u><em>2. The proper answer to this question is "</em></u></span><u><em>photosynthesis".</em></u>
Reason:
<u><em>Photosynthesis is the process that plants use to change (convert) light energy into energy (that other organisms can use). For example a apple tree uses </em></u><span><u><em>photosynthesis to make apples for humans, and other organisms to consume for energy.</em></u>
<em>Therefore the answer is </em></span><span><em>photosynthesis!</em>
<em>To sum up the answers are:</em>
<em>1.Sun</em>
<em>2.P</em></span><span><em>hotosynthesis</em>

Answer:
they are called autotrophs...
Explanation:
Autotrophs, which also called producers are the organisms which are able to produce the more complex substances like proteins fats and carbohydrates from what is around them (the sun and also carbon dioxide and water...)
HOPE THIS HELPS!!
