Answer:
5 lumbar vertebrae
Explanation:
As you can see in the image I annexed, a typical adult skeleton has 5 lumbar vertebrae (colored in red), they are cylindrical bones located between the rib cage and the pelvis, they are the largest segments of the vertebral column. These vertebrae carry all of the upper body’s weight, they protect the spinal cord and nerves in the vertebral canal, they also provide flexibility and movement to the trunk region.

Answer:
The first law of thermodynamics states that the total energy of universe is constant.
Explanation:
The first law of thermodynamics is related with the theory of energy conservation.The first law of thermodynamics states that energy cannot be created nor destroyed.
Energy can only be transformed from to one state to another state.For example light energy is converted to heat energy.
Answer: The correct answer for the question is- Resistance phase.
"General Adaptation Syndrome" is a model of stress, which was proposed by Hans Selye in 1936.
This model explains stress response ( through three phases that is Alarm phase, resistance phase, and exhaustion phase) and how it is related to aging and disease of organisms on exposure to stressful situations.
According to Resistance phase ( that is a second phase of stress response) of this model, the level of stress is declined once a body gives response to the stress. After the first phase ( alarming phase), overall temperature, blood pressure, and respiration becomes high.
As the stressor situation persist, the body is required to fight against the situation continuously, which is accompanied by outpouring of hormones.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
