3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams

Answers

Answer:

Explanation:

While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.

Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.

However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.

Answer: C

Explanation:

The landscape could be flooded. Houses and buildings may be restricted.

Answers

Answer:

Thermal energy

Explanation:

Temperature is measured in kelvin (For SI metric units).

Energy is always measured in joules (For SI metric units).

Celsius (°C), Fahrenheit (°F), and Kelvin (K) are three different units usually used to measure temperature in daily life situations. Joules is the SI unit of work or energy. Temperature and heat energy are related, but they are not the same.

Why do you only see red when you look at a red apple?

Answers

Answer:

Light reflects off the apple and the light travels to the retina where special receptors transmit messages to the brain, producing the color red that we see. Some colors are reflected while others are absorbed, so you only see red when looking at an apple instead of green or purple.
