Complete Solutions
Description:
This document provides a complete NAS 2 TCC study guide covering
key topics in anatomy, physiology, biology, and NAS (Network
Attached Storage) concepts. It includes clearly structured exam
questions with correct answers on the scientific method,
anatomical terminology, cell biology, biochemistry, and body
systems, as well as detailed NAS-specific knowledge such as RAID,
file systems, protocols, data security, scalability, and integration
with cloud services. The material serves both as a quick reference
and an in-depth preparation tool for the NAS 2 TCC exam.
What is the purpose of the scientific method? --- correct answer ---
The scientific method is an organized way to study the natural
world and find out how it works.
Exams Question and Answer:
What are the steps of the scientific method? --- correct answer ---
Ask a Question.
Do Background Research.
Construct a Hypothesis.
Test Your Hypothesis by Doing an Experiment.
,Analyze Your Data and Draw a Conclusion.
Communicate Your Results.
Distinguish between independent and dependent variables ---
correct answer ---An independent variable is the variable that is
changed or controlled in a scientific experiment to test the effects
on the dependent variable.
A dependent variable is the variable being tested and measured in a
scientific experiment.
Distinguish between control and experimental groups --- correct
answer ---An experimental group is the group in an experiment that
receives the variable being tested. One variable is tested at a time.
The experimental group is compared to a control group, which does
not receive the test variable.
Distinguish between hypothesis and theory. --- correct answer ---A
hypothesis is an attempt to explain phenomena. It is a proposal, a
guess used to understand and/or predict something. A theory is the
result of testing a hypothesis and developing an explanation that is
assumed to be true about something.
Define Anatomy and Physiology --- correct answer ---Anatomy is
the study of the structure and relationship between body parts.
,Physiology is the study of the function of body parts and the body as
a whole.
Identify the six levels of organization (chemical, tissue, etc.) ---
correct answer ---1) Chemical Level
2) Cellular level
3)Tissue level
4)Organ level
5)Organ system level
6) Organismal level
Identify the requirements for life: --- correct answer ---1.
Reproduction 2. Response/reaction to environment 3. Metabolism 4.
Growth.
Identify survival needs: --- correct answer ---survival needs (5):
nutrients, oxygen, water, stable body temperature, and atmospheric
pressure
What is homeostasis? --- correct answer ---The tendency of an
organism or a cell to regulate its internal conditions, usually by a
system of feedback controls, so as to stabilize health and
functioning, regardless of the outside changing conditions.
, What are the basic mechanisms of homeostasis? --- correct answer
---- Homeostatic control mechanisms have at least three
interdependent components: receptor, control center, and effector.
- The receptor senses environmental stimuli, sending the
information to the control center.
- The control center, generally the brain, signals an effector (e.g.
muscles) to respond to the stimuli.
- Positive feedback enhances or accelerates output created by an
activated stimulus.
- Negative feedback brings a system back to its level of normal
functioning such as adjusting blood pressure, metabolism, and body
temperature.
Anatomical position --- correct answer ---Anatomical position is the
description of any region or part of the body in a specific stance. In
the anatomical position, the body is upright, directly facing the
observer, feet flat and directed forward. The upper limbs are at the
body's sides with the palms facing forward.
SUPERIOR --- correct answer ---ABOVE THE HEAD IS SUPERIOR TO
THE NECK
INFERIOR --- correct answer ---BELOW THE NECK IS INFERIOR TO
THE HEAD
