Professor Hernandez was interested in how basketball player’s performance was affected by the presence of other people. There we
re two types of players: good players and bad players. They were tested under two different conditions: alone or in the presence of an audience. The basketball players were to shoot ten shots from atleast ten feet away from the hoop. What are the Independent Variables (there are two) and the Dependent Variable?
Independent variable - Player being good or bad , presence of audience
Dependent variable - Performance of player
Explanation:
Independent variables are the constant variable in an experiment whose effect is studied on the subject of the experiment. While dependent variables are those which are dependent upon the independent variable.
Here, performance of the player is independent variable which is dependent upon the presence of audience. Hence “presence of audience” is the independent variable. Also , the type of player is also an independent variable which shall effect the performance of an individual player
Explanation:Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
4. c) They result in production of diffusible second messengers
Explanation:
G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.
This is because the population would reach conveying capacity. This way, the support would be extended and inadequate to sustain the high Chipmunk population. The increased competition for scant resources between the Chipmunks would result in continued deaths rate of individuals that is important than the birth rate.
