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.

Even though streams that flow through valleys generally move very fast, the stream load is
mihalych1998 [28]

Answer:

D

Explanation:

The gradient in bed load is mostly made up mostly of gravels and sands, broken down versions of larger boulders and rocks, which are most commonly found in mountainous areas. Streams with low gradients cannot carry bed load down stream because it moves slowly and without much force. Gravels and sands couldn't move downstream because the water flow isn't strong enough to move them or to keep them in motion.

1. Negative feedback is bad for your body. True or false 2. Both negative and positive feedback works in a loop. True or false.
andrezito [222]

Answer:

1. False

2. True

3. True

4. True

Explanation:

Negative feedback (or balancing feedback) happens when some capacity of the yield of a framework, cycle, or system is taken care of in a way that will in general decrease the variances in the yield, regardless of whether brought about by changes in the input or by different unsettling influences.

Though certain feedback will in general prompt unsteadiness through outstanding development, wavering or disorganized conduct, negative feedback for the most part advances steadiness. Negative feedback will in general elevate a settling to balance, and diminishes the impacts of bothers. Negative feedback loops in which the perfect measure of adjustment is applied with ideal planning can be entirely steady, exact, and responsive.
