But it depend on what type of energy producing technologies you're talking about.
BioChar , a technology that uses Charcoal to produce energy will positively impact soil fertility because it is really rich in carbon.
On the other hand Nuclear related energy producing technology can negatively impact soil fertility
Answer: ADAPTIVE COLORATION
Explanation:
Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.
Adaptive coloration may be grouped into :
--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.
--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.
--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.
A synovial joint is surrounded by a two layer <em>joint capsule</em> which encloses a fluid filled space called the <em>synovial cavity</em>. The outer layer of this structure consists of <em>dense connective tissue</em> which is continuous with the periosteum of each bone. The outer layer may be reinforced by <em>ligaments</em> which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule. By definition, the structures, such as some ligaments, that are located outside the capsule are called <em>accessory structures</em>. The inner layer of the joint capsule is the <em>synovial membrane</em>, consisting of loose connective tissue. The inner lining of the joint capsule secretes a fluid called <em>synovial fluid</em>. This fluid is viscous, and moistens and lubricates the surfaces within the joint capsule
