Answer:
A
Explanation:
it has more matter in given area, so it is denser.
The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.
The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.
The normal osmolality of intracellular and extracellular fluid is 300 mosm, which makes them in osmotic<span> equilibrium. </span>
<span>This condition is better described as isosmotic. Water moves from high salt concentration to low salt concentration due to osmosis. The osmotic pressure of the extracellular fluid equals the osmotic pressure of the intracellular fluid (300 mosm), therefore no fluid movement across the plasma membrane.</span>
The mutation occurs in somatic cells from the skin. The mutated cells usually die causing sunburn, in worst cases, it can cause skin cancer. The DNA that is transmitted to the offspring is located in the germinative cells that are not affected.
The false statement is: (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind.
Transcriptional regulator or factor is protein with the ability to control and regulate gene expression at the transcription level by binding to DNA. Transcriptional factors have domain-DNA-binding domain which contains structural motif that recognizes DNA and it is responsible for the attachment to specific DNA sequence. It usually binds to the DNA major groove (hydrogen bonding) because it is less degenerate than that of the DNA minor groove.
Transcriptional factors also contain trans-activating domain for the binding of other proteins and signal-sensing domain for the detection of external signals.
