Answer:
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Explanation:
Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Answer:
The correct answer is - contains many genes for transcription factors that are present in cnidarians and bilaterian animals.
Explanation:
Placozoans are the simplest known metazoan organism known on earth and found in warm water and all over the globe. Placozoans are very small approximately 2 to 3 mm.
These are basal forms of marine free-living multicellular organisms. In the molecular studies, it is found that they have similar genes that are present in cnidarians and bilaterian animals for transcription factors.
Answer:
The correct answer is Broca's area or Wernicke's area.
Explanation:
Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.
The condition known as aphasia generally takes place suddenly, usually as the outcome of a head injury or stroke, however, it can also arise gradually, in the individuals suffering from a brain tumor. The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.
Answer:
Pulmonary veins
Explanation:
In the circulatory system, the heart is responsible for for pumping oxygenated blood throughout the body and deoxygenated blood to the heart.
Normally all veins carry deoxygenated blood. However the pulmonary vein is the only vein that carries oxygenated blood.
They carry oxygenated blood from the lungs to the heart.
However the Superior and inferior vena cava are responsible for delivering deoxygenated blood to the heart.
Answer:
B. By taking in inorganic substances
Explanation:
When you think of autotrophs, you may think of plants, and how do plants get nutrition?
By taking in inorganic substances like carbon dioxide or sunlight, then converting it into energy.
