Because of the severe impact that we impose on the land, air, and water, conservation has
become increasingly important.
Conservation is using natural resources wisely and not contributing to pollution of the land, air or water. Human activities can benefit the environment and help preserve resources.
Conservation can include small-scale clean-up projects along roadways or building fences to prevent dune erosion to large-scale beach renourishment. Planting trees is another way to support conservation as trees are too often removed without being replanted.
The phrase “Reduce, Reuse, and Recycle” has been a catch phrase of the late 20th and early 21st centuries.
The pulmonary circuit transports blood to the lungs. The blood is oxygenated there and then carried back to the heart. Gaseous exchange happens in the lungs:
Carbon dioxide diffuses from the blood into the air in the alveoli.
The genetic code is said to be Universal because a codon represents the same protein in almost all organisms.
Hope this helps!
