Provide brief overview of the nervous system and its role in the maintenance of homeostasis.
Alona [7]
Explanation:

The nervous system has two major anatomical subdivisions:

Central Nervous System: Composed of the brain (inside the skull) and the spinal cord (inside the spinal column).

The brain and spinal cord are responsible for processing and integrating the various sources of information to allow us to develop a response. Therefore, the main function of the somatic nervous system is to connect the Central Nervous System with the organs and skeletal muscle to carry out our daily functions.

Peripheral nervous system: it is everything that is outside the bone cavity and is formed by the nerves and nerve ganglia that extend outside the central nervous system.

The peripheral nervous system has a somatic component, which is associated with the voluntary control of body movements through the use of skeletal muscles. This means that it is responsible for all the functions that we are aware of, including the movement of our arms, legs, and other parts of our body.

On the other hand, the autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiological processes. These processes include heart rate, blood pressure, breathing, digestion, and sexual arousal. The autonomic nervous system contains three divisions: sympathetic, parasympathetic, and enteric.

Due to the above relationships and anatomical subdivisions we can say that the nervous system is responsible for regulating and maintaining homeostasis. In fact, through its receptors, neurotransmitters, nervous inputs, and outputs, the nervous system keeps us in touch with our environment, both external and internal.

We can conclude that the correct answer is:

A human-centered worldview states that humans, as the owners of Earth, can treat resources as they see fit.
zzz [600]

Answer:

Human centred world view is the idea that says that humans are the most important species and representative of the earth and can use resources as much as needed.

Explanation:

It also focuses on the benefits and threats of the natural environment to the humans. Earth centred world view says that the nature is available for every species on the earth and the earth is not under our control.

Environmental world view gives us an idea about our role in the environment and our activities that causes positive or negative effect on the environment and also understand how does the world does its function.

Which best describes the scientific process
olya-2409 [2.1K]

Answer:

The scientific method is a methodology to obtain new knowledge, which has historically characterized science, and which consists of systematic observation, measurement, experimentation, and the formulation, analysis and modification of hypotheses.

Explanation:

The main characteristics of a valid scientific method are falsifiability, and the reproducibility and repeatability of the results, corroborated by peer review. Some types of techniques or methodologies used are deduction, induction, abduction, and prediction, among others.

The scientific method encompasses the practices accepted by the scientific community as valid at the time of exposing and confirming their theories. The rules and principles of the scientific method seek to minimize the influence of the subjectivity of the scientist in his work, thus reinforcing the validity of the results, and therefore, of the knowledge obtained.
