Scientific Method
Observation, Question, Hypothesis, Experiment, Data Collection, Conclusion, and Retest (if needed)
Scientific Method
The smallest unit of life and the basic building block of all living organisms
What is a cell?
The basic unit of life that all living organisms are composed of
What is the cell?
They have a great capacity as energy source, we use it as primary source of energy. In vegetables they have structural functions.
Carbohydrates
A logical prediction about your "testable" question. (an educated guess)
Hypothesis
Variable kept constant so it does not affect the experiment
Controlled variable
Term that describes a group of similar cells that work together to perform a specific function. Some examples are blood, bones, skin, cartilage and breast milk.
What is a tissue?
Mechanical displacement of some or all structures. It can be internal or external displacement.
Movement
Mention the respective building blocks of biomolecules (4)
monosaccharides, amino acids, nucleotides, glycerol, and fatty acids.
It is the integration of biotic factors (communities) and abiotic factors
Ecosystem
The variable that the experimenter decides to change to see if there is or is not an effect.
The variable manipulated by the researcher, the one being changed.
Independent Variable (Manipulated Variable)
Dependent Variable
Set of nonliving factors of an ecosystem: Temperature, humidity, type of soil, etc.
Abiotic factors
Give an example of how a living organism responds to an environmental stimulus.
A plant growing towards sunlight or an animal moving away from a heat source?
They are the elements of the periodic table that mostly makeup life. Carbon, hydrogen, oxygen, nitrogen. (Sulfur, Phosphorus*)
Bioelements
The ability to maintain a relatively stable internal state, structure and physiological conditions that persists despite changes in the world outside
Homeostasis
Is one in which the researcher has left all the variables constant.It serves as a standard to make a comparison with the experimental group
Control group
It is a set of populations of different species that are related to each other.
Community
Name two common methods of reproduction used by living organisms.
What are sexual reproduction and asexual reproduction?
Mention at least 3 functions of proteins and their classification from simpler structure to more complex structures.
structure or support (collagen, muscles), and enzymes to speed up the chemical reactions, hemoglobin to transport oxygen into the cells, Immunity (antibodies), Hormones.
Amino acids, peptides, and polypeptides.
They are the main constituent of cell membranes. It has a polar head and non-polar tails.
Phospholipid
The intervention group was given YummyTooth toothpaste, while the control group was given an identical toothpaste that did not contain the secret ingredient in YummyTooth (placebo toothpaste). Subjects were observed brushing their teeth 3x per day with the assigned toothpaste (by teacher or parent). 6 months later, dental appointments were scheduled, and the number of dental caries present in each child was reported.
Identify: Control group, dependent variable and independent variable
Control group: Children with placebo toothpaste
Dependent variable: Caries development
Independent variable: The paste the children are given, either YummyTooth or the placebo one
The highest level of biological organization that encompasses all living organisms and their interactions with the Earth's atmosphere
What is the biosphere?
List the 8 characteristics of life that can be used to identify if something is alive.
What are metabolism, growth, reproduction, organization& complexity, homeostasis, response to stimuli, movement, and evolution?
Mention 2 examples of complex carbs used as storage and 2 examples of complex carbs used for structure
Storage: glucogen, starch
Structure: cellulose, chitin
Is a virus considered a living organism? What are the specific life characteristics they totally or partially exhibit (3)?
It is not alive, but they do present Evolution, it shows some organization and complexity, it can reproduce with a host.
