provide the barrier that marks the boundaries of a cell.
Operons afford the organism the opportunity to
simultaneously regulate transcription of multiple genes, whose products are
active in the same process. Operons lead to the synthesis of groups of functionally
related enzymes, usually from a single mRNA transcript hence makes regulation of
the genes highly efficient.
Answer:
Over time the beetle population will adapt as a result of natural selection because the beetles "desired" by the birds will be eaten and their population will dimish as a result. The beetles that are not eaten by the birds will have a chance to allow their population to grow because a. they aren't being eaten and b. they have more space as the other colored beetle's population is shrinking. Causing the eaten species to become less prominant and the not eaten beetle's population to grow and take over in place of the other beetles.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
D) because those birds are scavengers and therefore there will be competition in finding food and then to fight off the other birds so that you can get the food first.
