The body's response to stress involves a fight-or-flight response coordinated by the sympathetic nervous system and the HPA axis. Stress can be triggered by traumatic or significant life-changing events. Long-term stress can lead to serious health conditions like heart disease due to our body's limitations in adapting to chronic stressors.

The reaction of the body and mind to disturbing or stressful events is a complex physiological and psychological process. During stress, the body's primary response is the fight-or-flight response, which involves coordinated activities of the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis. This response was first identified by Walter Cannon in the early 20th century.

Endocrinologist Hans Selye referred to these physiological reactions to stress as part of the general adaptation syndrome, which has three stages: alarm reaction, resistance, and exhaustion.

Stressors can be long-term (chronic) or short-term (acute), and can range from traumatic events like natural disasters or military combat to major life changes like divorce, or moving homes. The response to such stressors can cause a variety of mental and physical symptoms, including increase in heart rate, dry mouth, and if serious enough, may manifest as post-traumatic stress disorder (PTSD).

We also adapt to changing emotional circumstances over time, akin to sensory adaptation, and we gradually revert to our original baseline happiness levels after significant events. Lastly, chronic stress over extended periods can lead to health consequences like heart disease due to the limitations of our body's ability to adapt to long-term stressors.

Answer:

The digestion takes a long time or indigestion happens.

Explanation:

Our stomach secretes the HCL which helps in the digestion of different foodstuffs. It maintains the normal PH of the stomach. But sometimes the acid level in the stomach increases for which one needs antacids. Antacids are bases that react with the acids of the stomach and neutralises the acidic activity. Antacids contain magnesium hydroxide, aluminium hydroxides, sodium bicarbonate. These are all mild bases.

If the PH of the stomach is normal and one consumes antacid in the empty stomach, then it neutralises the acid of the stomach. The stomach environment acts as a buffer or alkaline. The carbohydrates, proteins, fats take a long time to digestion and also creates disturbance in the smooth. The hamburger has carbohydrates and proteins. Because no acid is there to breakdown this complex foodstuff, it leads to indigestion..

Final answer:

Temperate grasslands and savannas both have dense vegetation dominated by grasses and share adaptations to survive periodic fires, conditions which contribute to the limited presence of trees.

Explanation:

Two similarities shared by temperate grasslands and savannas are the domination of grasses in the vegetation and adaptations to periodic fires. Both biomes have vegetation that is very dense with few trees, primarily because of conditions such as low precipitation, which doesn't support large forest growth, and frequent fires, which prevent tree domination by clearing out saplings and shrubs. In addition, both ecosystems have adapted to these unique environmental conditions, resulting in grasses that are both fire-resistant and capable of thriving in soils enriched by the regular burning of plant material.

Perception is the process of obtaining and interpreting sensory information from our environment, assisting us in interacting with the world. This sensory information, obtained through perception, is integral to all our senses. The conversion of a stimulus into an electrical signal in the nervous system through this process is called sensory transduction.

The process of obtaining information by using the senses is called Perception. Our sensory receptors are constantly gathering information from the environment. However, perception is the process which interprets that information and allows us to interact with the world. This sensory information we obtain through perception is organized, interpreted, and consciously experienced. The process that sensory information from a stimulus in the environment drives is referred to as 'bottom-up processing', while 'top-down processing' is driven by knowledge and expectation.

This process is instrumental in all of our senses: olfaction (smell), gustation (taste), equilibrium (balance and body position), vision, and hearing. Furthermore, our general senses or somatosensations also respond to stimuli like temperature, pain, pressure, and vibration. All these senses function to convert a stimulus into an electrical signal in the nervous system through a process called sensory transduction.

The main components of a biological membrane are the phospholipid bilayer, proteins, and carbohydrates.

The phospholipid bilayer is made up of two layers of phospholipids, with hydrophobic fatty acid tails oriented towards the center and hydrophilic phosphate heads facing outward.

Proteins are scattered throughout the membrane, either inserted within it or attached to it. Some of these proteins span the membrane and serve as transporters for materials in and out of the cell.

Carbohydrates are attached to proteins and lipids on the outer surface of the membrane, forming complexes that help identify the cell to other cells.

Cellular cytoplasm is primarily composed of water, making up around 70-80% of its composition. The water provides a medium for molecular transport and chemical reactions within the cell.

The primary substance that makes up cellular cytoplasm is water. Water accounts for about 70-80% of the cytoplasm's composition. The cytoplasm is a jelly-like substance where the cellular components, or 'organelles', reside. These other components include proteins, lipids, and salts. However, these serve more as crucial functional components rather than the main substance. The high water content facilitates many cell processes by providing a medium for molecular transport and chemical reactions within the cell.
