What is the main source of energy for most processes at earths surface
erica [24]
<span>Carbohydrates.
Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.<span>

Rainbow [258]

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.

Which of the following statements is correct regarding the evolution of flight?
xxTIMURxx [149]

Answer:

d.The wing-assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes.

Explanation:

Two theories were given to explain the origin of avian flight. The top-down theory suggested that the birds' ancestors were tree dwelling species. They took help of wings to glide from tree to tree in order to avoid predator or catch prey. The bottom up theory suggested that the birds' ancestors were ground dwelling species. They took help of wings to maintain a balance and provide a lift for efficient running.

Wing-assisted incline running was a mixture of both the above theories and gave a balanced view point. According to it, birds' ancestors used wings to maintain a balance while running up inclined slopes. The wings helped them to save energy while scaling slopes and eventually a flight mechanism was also developed.
