In an experiment, a scientist compares the effect of adding acid rain to samples taken from two different lakes, the scientist observes that ten drops of acid rain added to water taken from lake minnetonka in southern minnesota does not change the ph from 7.5, but ten drops of acid rain added to water take from upper kintla lake in glacier national park causes the ph to change from 7.5 to 5.2. which conclusion is supported by these observations

The conclusion is that lake Minnetonka acts like a buffer solution, but the  water take from Upper Kintla Lake does not.

Explanation:

A buffer solution is an aqueous solution that contains a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. When a small amount of strong acid (like acid rain) or base is added to a buffer solution its pH remains almost the same, like in the water of lake Minnetonka.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
