Fmri scans have allowed us to make great advances in our understand of the roles of different regions of the brain. Suggest why this may be and give some examples of areas of research which you think might benefit from this study method
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.

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
Biosphere and atmosphere.
Explanation:
Biosphere refers to the living organisms lives on the earth surface. All plants takes carbon in the form of carbondioxide gas from the atmosphere for the production of glucose in the process of photosynthesis and releases carbondioxide by the living organism in the process of respiration as a waste product. We can conclude from this discussion that photosynthesis acts to transfer carbon between two Earth systems such as biosphere and atmosphere.
How does interphase prepare cells for mitosis
Answer: During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
Explanation:

kelp forest could help protect the ocean animals from ocean acidification what evidence supports this claim and explain why the evidence supports the claim
Answer:
Kelp is an ecologically and economically important foundation species in California, where forests line nutrient-rich, rocky bottom coasts. One of the detrimental impacts of increased carbon in the atmosphere is its subsequent absorption by the planet’s oceans, which causes acidification – a chemical imbalance that can negatively impact the overall health of marine ecosystems, including animals people depend on for food.
Kelp has been targeted as a potentially ameliorating species in part because of its speedy growth – up to 5 inches per day – during which it undergoes a large amount of photosynthesis that produces oxygen and removes carbon dioxide from the water. In Monterey Bay, the effects of giant kelp are also influenced by seasonal upwelling, when deep, nutrient-rich, highly acidic water from the Pacific is pulled toward the surface of the bay.

Bill left a hammer out in the rain all day. The next morning it had rust on it. Oxygen and a metal chemically combine to form rust. What is rust an example of? a. A mixture b. An element c. A solution d. a compound
Answer:
d. a compound
Explanation:
Rust is also known as "iron oxide." It is a compound that is very common around the world. This compound is formed because iron readily combines with the element, oxygen. This is the reason why it is not common to find pure iron in the environment. The process of an iron rusting is called "corrosion."
The speed of rusting largely depends on the electrolytes present. Rain is considered a better electrolyte that speeds up the rusting of the iron than pure water. Thus, this is the reason why Bill's hammer had rusts on it the next morning.

O A. Asian elephants tend to be smaller than African elephants.
B. The pill contains 5 mg of aspirin.
O C. The bottle holds 2.3 liters of water.
O D. The bridge can support 200 tons of weight.
Answer:
A. Asian elephants tend to be smaller than African elephants.
Explanation:
Stating that Asian elephants tend to be smaller than African elements is a qualitative observation.
A qualitative observation are data often gathered with our senses of sight, touch, feel, tastes etc.
By our sense of sight we can compare between two elephants to know which is bigger or smaller. Quantitative observations are measured or calculated.
