Answer:

Vertical distance between contours is called contour interval

Explanation:

Contour lines are lines that connects point of equal height. The vertical distance or the difference in elevation between two contour lines is known as contour interval. For example a set of 100 contours is used to represent a hill of height 500 ft. So, the vertical distance between each contour will $\frac{500}{100} \\$ feet

$= 5$ ft contour interval.

A line drawn on a topographic map to indicate ground elevation or depression. If the contour intervals are closer together, the steeper the elevation.

Deciding between recycling of conventional plastics and developing biodegradable plastics is a complex issue because:___________

Julli [10]

Answer:

Conventional plastics-

"Plastics are typically organic polymers of high molecular mass, but they often contain other substances."

Composition-

"Oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination.

Biodegradable plastics-

"They are largely manufactured from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers."

Explanation:

Complex Issue-

Diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all ‘good’ or petrochemical-based products are all ‘bad’.

Biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.

Explain why biodiversity is essential to the health of an ecosystem Think about the complex interactions in an ecosystem and how

mixer [17]

Answer:

Biodiversity is very essential to the health of an ecosystem.

Explanation:

Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.

Oxygen and Carbon Dioxide exchange as a result of the interaction of which two body systems

miskamm [114]

Answer:

Explanation:

The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.

The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.

* Blood cells isn't an organ system which makes 1 incorrect.

* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.

*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.

Answer:

transpiration; evaporation

Explanation:

Definitions:

transpiration - the process of water movement through a plant and its evaporation

evaporation - the process of turning from liquid into vapor (and releasing it into the air)

BOTH of these processes include releasing water into Earth's atmosphere.
