Answer:
E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
Answer:
The given blank can be filled with operator.
Explanation:
The proteins that assist in turning on or turning off the function of a specific gene by getting combined with certain sections of the DNA are known as transcription factors. The transcription factors that activate the transcription of a specific gene are known as activators, while that prevents transcription and is termed as repressors.
A repressor can be an RNA or a DNA binding protein, which prevents the articulation of genes by getting combined with the operator. A repressor, which binds with DNA prevents RNA polymerase from getting combined with the promoter, which further inhibits the transcription of the genes into mRNA.

Answer:
Hydrosphere
Explanation:
When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.
Weather is the atmospheric condition of a place over a short period of time.
The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.
This water in the atmosphere is forms rainfall, one of the elements of weather.
The sun causes an impact on weather by causing evaporation of water into the atmosphere.
This interaction takes place in the hydrosphere.
