When reproduction involves two parents, which two statements describe the offspring? A. Offspring differ genetically from both parents. B. Offspring are genetically identical to one parent. C. Offspring are genetically identical to one another. D. Offspring differ genetically from one another. SUBMIT

A. Offspring differ genetically from both parents and D. Offspring differ genetically from one another.

Explanation:

Sexual reproduction results in offspring with genetic variation. Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited.

I also took the test and got these right.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
