Answer the following question given this paragraph: Some bacteria depend on other organisms for survival. For example, some bacteria live in the roots of legumes, such as pea plants ( Figure below ). The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use. Meanwhile, the root provides nutrients to the bacteria. In this relationship, both the bacteria and the plant benefit, so it is known as a mutualism . Q: In biology, a relationship that benefits both entities is known as what? Choices: - naturalism - altruism - predatory - mutualism A:
(Answer)
mutualism
Ques: Answer the following question given this paragraph: You hit a baseball out of the park and head for first base. You're excited.

Answer the following question given this paragraph: Figure 9.24 (a) In the case of the wheelbarrow, the output force or load is between the pivot and the input force. The pivot is the wheel's axle. Here, the output force is greater than the input force. Thus, a wheelbarrow enables you to lift much heavier loads than you could with your body alone. (b) In the case of the shovel, the input force is between the pivot and the load, but the input lever arm is shorter than the output lever arm. The pivot is at the handle held by the right hand. Here, the output force (supporting the shovel's load) is less than the input force (from the hand nearest the load), because the input is exerted closer to the pivot than is the output. Q: In the case of the wheelbarrow, the output force or load is between the pivot and the what? Choices: - velocity force - Driving Force - density force - input force A:
(A).
input force
