the graph shows the relationship between the number of cigarettes smoked per day and the increased risk of lung cancer what name is given to this type of correlation

Positive correlation

Explanation:

When one variable increases, the other increases as well. In this case, a higher number of cigarettes smoked per day will see an increased risk of lung cancer as well.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
