Answer: B - transports oxygen and carbon dioxide for the respiratory system
The cardiovascular system consists in the heart and all blood vessels. Blood vessels lead the blood from the heart to the rest of the body and then brings it back. It's in the lungs, part of the respiratory system, where the gas exchange is going to happen. What that means is that oxygen is going to enter the blood while the carbon dioxide needs to be eliminated.
(If the option A, said carries hormones FROM the endocrine system, that would be also correct.)

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.

Describe the procedure of water reaching the leaves from the roots of a plant
Lisa [10]
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
