Answer:
When the tide recedes, some coastal areas are exposed to air for many hours.
Explanation:
Unless updated to live both on land and in water, the tidal zone can be a challenging place for an organism to survive. This is because during low tide, the ocean’s shoreline recedes deep into the ocean exposing the continental shelf before returning during high tide. Therefore if an organism adapts to water, it becomes exposed (and becomes vulnerable) during low tides. If an organism adapts to land, it becomes vulnerable during high tides. See the quagmire?
Answer:
a) Greenhouse Effect.
b) Nuclear Energy.
Explanation:
a) The Greenhouse Effect is one general effect of overuse of an environmental resource. Through this effect Earth's surface is warmed, destabilising environmental temperature. This effect is caused by the hydrocarbons overexploitation.
b) Nuclear Energy could be an option to decrease the hydrocarbons overexploitation. Even tough, nuclear energy doesn't produce that much greenhouse gases, that's why is an option that some governments are considering.
c) The earthquake that happened in Easter Island could be an indicative of environmental issues, because the greenhouse effect can produce earthquakes, due to the elevation of the Earth temperature, icebergs are melting in the Earth Poles, causing a bump effect in the Earth crust.
Melanophores are small pigments that are present in the dermis layer of the skin of a shark. They impart a gray color to the dorsal and lateral surface area of the shark. They help in background adaptation and countershading of the body, which makes a shark difficult to be seen.
