Carbondioxide, being a green house gas has the property of trapping the heat from the sunlight and thus increasing the temperature of the place. As more and more rain forests are cut down and burned, there is an increase in this green house gas in the atmosphere thus leading to a steady increase in the temperatures.
As we look at the graphs that are given, we can see that the graph C shows the steady increase in the temperature as the time passes. Hence option C is the right answer
Seems like an open ended question, the habitat organ was the ocean, more specifically is probably the sea floor, since that it is where sponges (basal animals) live
Answer:
D is rhe answer of rhis question.
Explanation:
collection of cells make tissue, collection of tissues form organ, similarly group of organs combine to form a system and when these systems combine it forms a whole body of organism.
Genetic drift is defined as a shift in the allelic frequency of a population. This can be caused by natural selection which is the differential survival and reproduction of individuals across a population due to differences in phenotype. Natural selection favors particular traits in a population hence these individuals are able to reproduce while the individuals with disadvantageous traits will pass their genes to succeeding generations. This way the allelic frequency of succeeding generation will be diferent from that of the parent population.
The answer should be a. receptor sites in the surface of the cell
hope this helps :)
