Overall, how has science impacted human health?
mixas84 [53]

Answer:

The correct answer is: <em>C. Increased average lifespan to 78 in the US.</em>

Explanation:

Science has impacted human health by increasing the average lifespan to 78 in the US. Over the last couple of decades, the life expectancy of Americans has increased significantly than what it was 200 years ago. This can be attributed to:

1. Vaccinations- Since the invention of vaccinations, diseases such as tuberculosis, cholera and polio which were major causes of death 200 years ago have virtually been eradicated in the US.

2. Abundant and safer foods available- Commercial and large scale farming has made a wide variety of nutritious foods easier to obtain.

3. Improved sanitation- Safer drinking water, sewage treatment and stricter food inspection has significantly reduced the rate of illnesses due to poor hygiene and sanitation.  

In these ways, science has impacted human health by increasing the average lifespan to 78 in the US.

Which type of anatomic structure are bird wings and butterfly wings when compared to each other?
Anna11 [10]

When compared to each other, bird wings and butterfly wings can be described as ANALOGOUS STRUCTURES,

Analogous structures are those body structures in animals, which are used to perform similar functions but which have different evolutionary history. They are also called convergent structures. These structures are formed as a result of the need for the animals to adapt to similar environmental conditions. For instance, both bird and butterfly use their wings for flying.
