The answer is; the skeletal system and the nervous system
The skeletal system (muscle and bone) give you rigidity and enable your legs to support your weight. The muscles also act on the bone as a fulcrum allowing it possible for them to contract and make motion possible.
The nervous system is important in the coordination of movement. The brain is the center for locomotor action. This ensures you are able to place one foot in front of the other in sequence and moving your arm in concert.
Answer:
Physiological reactions to stress in the alarm stage include: <em>increased heart rate and blood pressure, dilated pupils, rapid and shallow breath, and increased cortisol levels.</em>
Explanation:
Hans Seyle, a medical doctor proposed a model called the General Adaptation Syndrome (GAS) to explain the effects and stages of coping with the stress. The GAS model has three stages, known as:
1. Alarm stage
2. Resistance stage
3. Exhaustion stage
The <em>alarm</em> stage is the first stage of responding to stress. During this stage, the fight-or-flight response is activated when an individual is experiencing stress. This stage involves the following physiological reactions:
1. Increased heart rate
2. Increased blood pressure
3. Dilated pupils
4. Rapid and shallow breath
5. Increased cortisol levels
Answer:
Yet even an intact human brain can be biologically alive but incapable of consciousness, or “brain-dead.” Similarly, neither cellular nor viral individual genes or proteins are by themselves alive.
Explanation:
neither cellular nor viral individual genes or proteins are by themselves alive.
The answer is mitochondrion. Mitochondria are critical for the cell’s biochemical processes that require energy to be powered. Mitochondria are responsible for generating this power in the form of ATP through a process called chemiosmosis. Without ATP, the cell would immediately die since it would be incapable of performing virtually all biochemical processes that re required to sustain life.
