Answer:
Newton's third law of motion says that for every action there is an equal and opposite reaction.
Explanation:
This law explains that when two bodies interact with one another, two forces facilitates this process.These forces are opposite is action but equal in magnitude.For example, when sitting on a coach, the body exerts force on the coach downwards and the coach exerts an upward force on the body.These two forces are the action and reaction forces.
Answer:
10. 3
11. 1
12. 3
Explanation:
10. Everybody has different things that they find stressful. Stressful situations are associated heightened anxiety, fear, and worry. Different situations and life events can trigger stress. Public speaking is a good example of a stressful situation, as it often makes people nervous and uncomfortable. The other options are not usually associated with stress
11. After division of a cell containing 46 chromosomes (diploid), the genetic content is divided equally between 2 cells, producing two daughter cells with 23 chromosomes (haploid). Sex cells are the only cells in the body that are haploid. At fertilisation, 2 haploid cells come together to form a diploid cell.
12. After the whales died, the bones settled in the ocean sediments that moved with the changing land. The bones would not be preserved after animal activity or floating in the ocean. Options 4 and 5 do not explain how the whale bones ended up out of the water.
