Ques:Q: What term describes the energy of an object that is moving or has the potential to move? Read this paragraph and choose the correct option from the provided answers: Mechanical energy is the energy of an object that is moving or has the potential to move. It is the sum of an object's kinetic and potential energy. In Figure below , the basketball has mechanical energy because it is moving. The arrow in the same figure has mechanical energy because it has the potential to move due to the elasticity of the bow. What are some other examples of mechanical energy?. Choices: - stationary energy - molecular energy - thermal energy - mechanical energy A:

Ans:mechanical energy

Ques:Q: What is it called when pollen from one plant fertilizes another plant of the same species? Read this paragraph and choose the correct option from the provided answers: Pea plants are naturally self-pollinating. In self-pollination , pollen grains from anthers on one plant are transferred to stigmas of flowers on the same plant. Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination . The offspring that result from such a cross are called hybrids. Choices: - cross-typing - cross-breeding - cross - vegetation - cross-pollination A:

Ans:
cross-pollination
