Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life. Structural adaptations are physical features of an organism that adapted
through time. An example of this are the bills of a bird and the fur of bears
that they generally need for their survival; birds for hunting, and bears to
protect them from low climate areas.

Functional or
Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
What is an invasive species? they are plants/fungi/animals that isn't native to a specific area (an introduced species). They have the tendency to spread and cause damage too the environment, human economy, and/or human health. The Answer to your question is No. Not every species that is introduced to a specific area is invasive. The introduced species might have a natural predator that might eat it. The species may even be biologically, chemically, or mechanically controlled. I hope this helps you out:)
Answer: because oil is less dense than water and therefore it floats to the surface.
Explanation:
Answer:
In quiet breathing inspiration involves muscular contractions and expiration is passive.
Explanation:
Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.
During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.
During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.
