Answer: True

Explanation:

A cataract is a clouding of the lens of your eye. As one ages, proteins in the lens begin to break down and the lens becomes cloudy. One may not even realize they have a cataract because it usually grows very slowly and may not impede vision early on. While cataracts are rarely dangerous, after a number of years they will likely affect vision. Its important to note also that cataract is not caused by overuse of the eyes and it does not travel from one eye to the other.

Risk factors include aging, family history, high blood pressure, previous eye injury, smoking, obesity, heavy drinking and diabetes.

Therefore, from the above risk factors, we could expound that blood type (exposure) has no relationship with cataract.

At what point does high blood sugar cause damage
Amanda [17]
<span>High sugar levels slowly erode the ability of cells in your pancreas to make insulin. The organ overcompensates and insulin levels stay too high. Over time, the pancreas is permanently damaged. High levels of blood sugar can cause changes that lead to a hardening of the blood vessels, what doctors call atherosclerosis.</span>

According to Max Weber, all governments get their powers from:
ryzh [129]

Answer:

The answer is: letter B, the people.

Explanation:

Max Weber is a German sociologist and political economist.  He proposed a theory on "bureaucracy." This is an organizational structure that focuses on rules, procedures, processes, hierarchies, etc. among the employees. He introduced the three types of power:<em> legal power, traditional power and charismatic power. </em>

According to him "power is the ability to exercise one's will over others." This definition has been adopted by many scholars over time. And for him, all governments get their power from the people. The word "power" here is different from the word "authority." Power affects social relationships and "it is NOT coercion." It provides a strategic way to rule the people so they will obey.
