Q

What are the Fundamental Characteristics of life that are traits shared by all organisms
(M,R,G,R,R,D,A,C,A,E)

A
Movement
Responsiveness
Growth
Reproduction
Respiration
Digestion
Absorption
Circulation
Assimilation
Excretion
25
It is the characteristics of live where the change in position of the body or a body part, motion of an internal organ
Movement
26
It is the Characteristics of Life where it react to internal or external change
Responsiveness
27
Characteristics of life where it increases in size without change in shape
Growth
28
Characteristics of Life where new organisms or new cells
Reproduction
29
Characteristics of life where it uses of oxygen; removal of carbon dioxide
Respiration
30
Characteristics of life it breakdown of food into simpler forms
Digestion
31
Characteristics of life where the movement of substances through membranes and into fluids
Absorption
32
Characteristics of life where the movement within body fluids
Circulation
33
Characteristics of life where changing nutrients into chemically different froms
Assimilation
34
Characteristics of Life removal of metabolic wastes
Excretion
35
The physical and chemical events that obtain, release, and use energy
Metabolism
36
What are the Main Characteristics of organisms | C,E,R,H,O,R,G,D,E
``` Cells Energy Reproduce Homeostatis Organized Respond Grow Develop Exchange ```
37
The most abundant chemical in the body
Water
38
How many percent of water our body needed
60%-75%
39
Provides the body with needed nutrients. Needed for energy, raw building materials for growth and repair, and to regulate chemical reactions
Food
40
Force applied to something
Pressure
41
It is a pressure which is needed for breathing
Atmospheric Pressure
42
It is a pressure which is needed to move blood through blood vessels, our blood pH
Hydrostatic (Water) Pressure
43
As our body shivers our temperature increases | T or F
True
44
As our body sweat the temperature decreases | T or F
True
45
It is the maintenance of a variable, such as body temperature around an ideal normal value, or set point. It is the existence and maintenance of a relatively constant environment within the body.
Homeostasis
46
Homeostatic control mechanisms have at least 3 interdependent components
Receptor Integrating/Control Center Effector
47
One of interdependent where it senses environmental stimuli, sending the information to the control/integrating center (eg. Peripheral Chemoreceptors, which detect changes in Blood pH)
Receptor/Sensor
48
One of interdependent where it receives information from the senses and initiates the response to maintain homeostasis (eg. Hypothalamus)
Control/Integrating Center
49
It is a region of brain that controls everything from body temperature to heart rate, Blood pressure, satiety (fullness) and circadian rhythm (sleep and walk cycle)
Hypothalamus
50
One of the interdependent where any organ or tissue that receives information from the integrating/control center and acts to bring about the changes needed to maintain homeostasis (eg. Kidney, which retains water if blood pressure is too low)
Effector
51
It brings a system back to it's level of normal functioning. It is also a balance, maintain homeostasis (Eg. Blood pressure, metabolism, body temperature
Negative Feedback
52
It enhances or accelerates output created by an activated stimulus (Eg. Platelet aggregation and accumulation in response to injury)
Positive Feedback
