Reaction range. The concept of reaction range
posits that heredity sets limits on one’s intellectual potential
(represented by the horizontal bars), while the quality of one’s environment influences where one scores within this range (represented by the dots on the bars).
What is reaction range in relation to human development?
Range of reaction (or reaction range) is a concept in psychology, genetics, and related fields that
the expressed characteristics (or phenotype) of an organism depend both on genetic characteristics (or genotype) and the environment
.
What is a reaction range?
In genetics, reaction range (also known as range of reaction) is
when the phenotype (expressed characteristics) of an organism depends both on the organism’s genetic characteristics (genotype) and the environment
. For instance, two siblings raised together can have radically different IQs and natural talents.
What is the energy of activation quizlet?
Activation energy is
the energy required to break existing bonds, and form new bonds
. If a collision occurs with more energy than the activation energy, the reaction will occur. Rate of reaction is determined by the number of collisions that occur, and how effective they are.
Which of the following can change the activation energy of a reaction quizlet?
Which of the following can change the activation energy of a reaction?
Adding a catalyst to the reaction
.
How does Reaction range affect intelligence?
Reaction range refers
to limits set on IQ by heredity
. Environment determines where IQ will lie within these limits. There is a discrepancy in IQ scores between whites and some minority groups. There are both hereditary and environmental explanations for this discrepancy.
What does norm of reaction signify?
The Norm of Reaction is
a curve that relates
, for a given genotype, the contribution of environmental variation to observed phenotypic variation. The norm of reaction curve can be thought of as a mirror that reflects the environmental-effect curve into phenotypic space.
What effects does range of reaction have upon a person’s environment?
Range of reaction asserts that
our genes set the boundaries within which we can operate
, and our environment interacts with the genes to determine where in that range we will fall.
What is the range of the relation?
The range of a relation is
the set of the second coordinates from the ordered pairs
.
What is an example of the influence of nature?
A few examples of biologically determined characteristics (nature) include
certain genetic diseases, eye color, hair color, and skin color
. Other things like life expectancy and height have a strong biological component, but they are also influenced by environmental factors and lifestyle.
How does activation energy play a role in a reaction?
Chemical reactions need a certain amount of energy to begin working. Activation energy is
the minimum energy required to cause a reaction to occur
. … For a reaction to occur, existing bonds must break and new ones form. A reaction will only proceed if the products are more stable than the reactants.
What is the effect of a catalyst on a reaction?
The rate of a reaction can be increased by adding a suitable catalyst
. A catalyst is a substance which increases the rate of a chemical reaction but it is not used up (remains chemically unchanged at the end). It provides an alternative reaction pathway of lower activation energy.
What does activation energy do in a reaction quizlet?
What is activation energy? Activation energy is
the minimum amount of energy needed to start a chemical reaction
. What role does activation energy play in chemical reaction? Activation energy is the energy absorbed before it can start a chemical reaction.
Which type of reaction is always spontaneous quizlet?
Exothermic reactions
are always spontaneous. Endothermic reactions are never spontaneous. Endothermic reactions are never spontaneous. A reaction that leads to an increase in the entropy of the system is always spontaneous.
What type of reaction is always spontaneous?
A reaction which is
exothermic
(ΔH negative) and results in an increase in the entropy of the system (ΔS positive) will always be spontaneous.
Which of the following can change the activation energy of a reaction?
A catalyst
lowers the activation energy of a complex by providing a surface. So more molecules can have activation energy and convert to products. … Temperature and reactant concentration affect the rate of reaction but not the activation energy.
