Roller coasters, with their twists, turns, and loops, seem to defy everything we know about how objects move. Roller coaster des

igners use Newton's laws to
push people past their usual limits. Which statement identifies Newton's Law of Motion with the correct justification of that law? (DOK 2, AKS 8b)
OA Newton's first law is the law of inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
OB. Newton's first law is the law of force and acceleration. Since the rollercoaster is so massive, it will require more force to accelerate
OC. Newton's third law of action-reaction states that for every action, there is an equal and opposite reaction. This means that as you push down on the
seat, the seat does not push back on you with an equal force.
OD. Newton's second law is the law of force and acceleration. Since the rollercoaster is so massive, it will require less force to accelerate.

Write characterize progression of infectious disease.
vlada-n [284]

Answer:

* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.

* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.

Explanation:

Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.

To successfully control infectious diseases, it is paramount to see how the disease progresses.

remember to imagine that blood in the heart is color-coded according to its oxygenation status. What color of blood would you ex
Vinvika [58]

Answer:

Red blood.

Explanation:

Red blood is for oxygenated blood, while blue blood is for deoxygenated blood.

The blood in Isabelle's left ventricle would be red, in other words, oxygenated. The left ventricle has oxygenated blood because this blood was first in the right ventricle. Then, it went to the pulmonary arteries, which led the blood to the capillaries close to the alveoli in the lungs. In this area, the deoxygenated blood dropped the CO₂ and took O₂ becoming oxygenated blood. Now, this blood is color-coded red and will go to the pulmonary venules, then to the pulmonary vein, and from there, it will go to the left atrium. Lastly, it will go to the left ventricle to start the systemic circulation, which is the one that distributes the oxygenated blood in the body.
