Answer:
FMRI helps to measure and map the brains activities.
Explanation:
FMRI refers to Functional Magnetic Resonance Imaging. It helps to measure and map the brain's activity.
FMRI scan works by looking at the blood flow in the brain to detect areas of activity. Glucose is the main source of energy in the brain,but not stored in the brain. So when parts of the brain need energy o perform action, more blood flow in to transport more glucose.
FMRI scan helps doctors to map out the brain before surgery and provides more information about individual brain to prevent serious injury before the surgery.
It also helps doctors monitor a progressive condition like dementia to study how the disease progresses.
These are the only options to pick from ?
- It was a weakly reducing atmosphere
- It was hotter
Explanation:
The primordial earth’s atmosphere was mainly composed of carbon dioxide and methane. These are greenhouse gases that kept the temperatures of the atmosphere high because they trap infrared radiation that reflects off the earth's surface. These gases also made the atmosphere a reducing atmosphere due to the absence of oxygen. The most likely source of carbon dioxide was frequent volcanoes at the time and the methane from early anaerobic microbes.
The atmosphere changed when photosynthetic organisms evolved and caused the Great Oxygenation Event because they evolved oxygen.

Answer:c
Explanation:why i don’t know I just want the points
Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
