Answer:
The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.
It was for studying MIMICRY in snakes.
Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.
This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.
The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.
since it changes in the artificial snake

Answer:
Basophils
Explanation:
Basophils are a special type of white blood cells that are produced in the bone marrow and their main role entails inducing and maintaining allergic conditions.
In staining, Basophils shows dark blue granules which contains histamine, heparin and peroxidase. In preparation of Schiff reagent ; magenta molecule ( Fuchsin dye ); gives a range of colors from magenta to purple. The stain cause nuclei to become blue, and glycogen and fungi to become magenta in color.
Antagonsitic effect/interaction/response
In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest.
First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.
The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect.
Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.
Answer:
Within the geological structure of Cayuga Lake Basin there is a diversity of limestone sources, which would make it possible for the lake to be a good location for the construction of a cement-making plant.
Explanation:
Cayuga Lake, part of the so-called Finger Lakes, located in New York, has an extension of about 40 miles. This lake is of great economic and ecological importance, because it allows fishing and recreation activities, besides being a place of passage for migratory birds.
The Skaneateles, Onandaga, Marcellus, Manilius, Moscow and Tully formations are an important source of limestone of variable quality, from which lime can be obtained for the manufacture of cement.
Although the presence of limestone would be ideal for building a cement-making plant, a project of this size should consider the environmental impact it could have.
