Drug resistance exists among all individuals in a population.
Heritable variation does not exist among individuals in a population.
Environmental variation exists for traits among individuals in a population.
Answer:
Heritable variation exists for traits among individuals in a population.
Explanation:
According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
The chip contains more lipids than the saltine.
Answer:
Behavioral adaptation
Explanation:
There are mainly three types of adaptation seen in an organism that are structural, physiological, and behavioral adaptation. Structural adaptation is mainly physical adaptation in some structures of the organism like teeth are different in different organisms according to the food they eat.
Physiological adaptation is the adaption occurs due to change in the external stimuli in physiology of an organism. Behavioral adaptation is the adaptation that helps organism to survive in their environment. Their behavior can be learned or present from birth.
Spittlebugs release foam to hide in branches is an example of behavioral adaptation because this is the instinct of spittlebugs which protects them from predators and helps it to survive in its habitat.
So it is in the behavior of spittlebugs to release foam when it feels a threat and when it does not feel threat it does not form the foam.
Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.
