Hellbenders are fully aquatic, which means they cannot live out of water and do not try to crawl out of their stream or river habitat. As river water flows over their body, oxygen is taken up by tiny blood vessels in the skin and carbon dioxide is released
As humans sometimes experience, a cold environment can result in<span> </span>shivering<span>. This is when skeletal muscles begin to shake in small movements, creating warmth by expending energy. Humans can also sweat in high temperatures. The water on the surface of the skin is able to absorb a lot of heat during evaporation, resulting in cooling of the body.</span>
Answer:
The potential risks associated with plant-based pharmaceuticals include: pollen transfer to related species, contamination of non-transgenic crops intended for the consumption by humans, allergic reactions to the drugs produced from the genetically engineered plant, and persistence of genetically engineered material to persist in the environment and accumulate in non-target organisms. Risk assessment of plant-made pharmaceuticals should be reviewed on a case-by-case basis because the plants used to produce proteins each have different risks associated with them.
Answer:
Mechanical isolation
Explanation:
mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.
The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
Answer:
Lamellae
Explanation:
These lamellae are remnants of osteons whose matrix components have been almost completely recycles by osteoclasts. growth of the bone.
