earth science

Q: Q: Speed takes distance and what else into account? Read this paragraph and choose the correct option from the provided answers: Speed just takes distance and time into account. How might direction be considered as well?. Choices: - gravity - matter - energy - time A:
A: time

Question: Q: What force pulls object downwards to the earth? Read this paragraph and choose the correct option from the provided answers: Gravity near the Earth pulls an object downwards toward the surface of the Earth with an acceleration of . In the absence of air resistance, all objects will fall with the same acceleration. The letter is used as the symbol for the acceleration of gravity. When talking about an object's acceleration, whether it is due to gravity or not, the acceleration of gravity is sometimes used as a unit of measurement where . So an object accelerating at 2g's is accelerating at or. Choices: - momentum - kinetic energy - motion - gravity A:
Answer: gravity

*Question*
Q: What do wind turbines turn wind energy into? Read this paragraph and choose the correct option from the provided answers: Wind energy is energy provided by the blowing wind. Wind turbines, like those in Figure above , can turn wind energy into electricity. The wind blows because of differences in heating of Earth's atmosphere by the sun. There will never be a shortage of wind. Choices: - hydrogen - carbon - oxygen - electricy A:
**Answer**
electricy

(Q).
Q: What term is used to describe an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination? Read this paragraph and choose the correct option from the provided answers: The adaptive, or acquired, immune response takes days or even weeks to become establishedmuch longer than the innate response; however, adaptive immunity is more specific to an invading pathogen. Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. An antigen is a molecule that stimulates a response in the immune system. This part of the immune system is activated when the innate immune response is insufficient to control an infection. In fact, without information from the innate immune system, the adaptive response could not be mobilized. There are two types of adaptive responses: the cell-mediated immune response, which is controlled by activated T cells, and the humoral immune response, which is controlled by activated B cells and antibodies. Activated T and B cells whose surface binding sites are specific to the molecules on the pathogen greatly increase in numbers and attack the invading pathogen. Their attack can kill pathogens directly or they can secrete antibodies that enhance the phagocytosis of pathogens and disrupt the infection. Adaptive immunity also involves a memory to give the host long-term protection from reinfection with the same type of pathogen; on reexposure, this host memory will facilitate a rapid and powerful response. Choices: - variation immunity - autoimmunity - herd immunity - adaptive immunity A:
(A).
adaptive immunity
