50 POINTS!!!! Heart disease is the leading cause of death among both men and women in the United States. It is usually caused wh
Paul [167]

Answer:

Heart disease is prevalent in the United States because... well, we consume a lot of sodium and fat. If you look at the stats, we are the third country with the most obese residents, with a whopping percentage of 36.20% people in the US tipping the scales. Also, people smoke a lot. Not just adults, but teenagers. Because of this, youngsters tend to also get heart disease too, despite the small age. According to cdc.gov, a family history of heart disease increases the rates, especially if one of your relatives got it under the age of 50. Due to the smoking rates at a young age, those diseases tend to transfer and increase the rates of the future US citizens.

Heart disease can affect a lot of organs, but listing them would be a pain. Here are the highlights: The heart and the lungs are intimately connected. This means that having heart disease may lead to having trouble breathing. You may have chest pains, and particularly in woman, it may affect the digestive system and cause stomach pain when eating.

Which is the main reason cells are replaced in the body?. The cells are too large.. The cells are inactive.. The cells are damag
anygoal [31]

The right answer is The cells are damaged.

Take the example of skin cells.  

The skin consists of two tissues:

* the outermost, the epidermis, resting on a vascularized connective tissue,

* the dermis.

In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.

On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
