Most of the energy that your brain uses comes from
evablogger [386]

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

Cells can interact with other cells?
Allisa [31]

Answer:

Yes. Cells have 'cell receptors' that are used to receive messengers like hormones to communicate. Cell receptors have specific shapes that fit the shape of the messenger that they want to receive. Organs like the pancreas send our these messengers to the cells to order them to do different functions.

Explain how the human immune system responds to a viral infection.
nikdorinn [45]
Infected cells create and release small proteins known as interferons, which help the immune system fight viruses. Interferons stop viruses from replicating by interfering with their ability to multiply within infected cells.
