Answer: Sympathetic
The alarm reaction to danger that is triggered by anxiety primarily involves the sympathetic nervous system
Explanation:
The sympathetic nervous system (SNS) primarily stimulates many parts of the body for action in times of danger or emergency situations.
During this process, a hormone known as adrenaline (the emergency hormone) would be released, and effects such as sweating, increased heartbeat, raised blood pressure will follow.
Answer: Promoter
Explanation:
Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called <u>RNA polymerases which perform this process of transcription</u>. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.
A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. <u>The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is</u> and contains the information needed to activate or deactivate the gene it regulates. <u>The promoter has a binding site for the RNA polymerase enzyme </u>in charge of mRNA synthesis and when it recognizes this site, transcription begins.
Answer:
Sunlight allows plants, algae, and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere
