Answer:
1) A cardiovascular system is an organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes.
2) "Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart."
3) A heart attack is a blockage of blood flow to the heart muscle.
According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis. This hypothesis is key to said experiment because it provides the starting point from which the professional can begin the procedure, as it helps focus on the subject that one is trying to get results from. Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.
Answer:
A). Metaphors fail when they have been used so often that readers gain nothing new from them.
Explanation:
Metaphors are demonstrated as one of the most commonly employed literary devices that involve an implicit comparison between two distinct things sharing common characteristics. For example, she is the moon(girl and moon are completely distinct from each other but share the common characteristic of bringing light in the darkness).
As per the question, metaphor fails 'when they are employed so often that the readers gain nothing new from them.' Metaphors are primarily employed to offer <u>an implicit or symbolic comparison that not only helps the reader transform their understanding but also artistically provides them 'an intrinsic pleasure and transcend the boundaries of literal meaning.' But if they are used so frequently that readers stop gaining that pleasure, experience, and understanding metaphors fail</u>. Thus, <u>option A</u> is the correct answer.
It is a measurement of a plane angle .
