The following statement is false: MOST US STATES PROHIBIT THE IMPORTATION OF ANIMAL SPECIES LIKELY TO BECOME INVASIVE IF THEY ESCAPE INTO THE WILD.
Presently, most US states do not have any law, which prohibit people from bringing into the US animal species that are likely to become invasive.
Invasive plant and animals are a great source of problems in America. These species usually destroy habitats and native species, this usually throw the ecological communities out of balance. The government spend as much as $120 billions every year to control these invasive species.
I would say B) <span>The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.
This is because the shoot of the plant is attracted towards the sun, as the chloroplasts in the leaves need sunlight to make food. As well, the roots are attracted downward to absorb more water and minerals from the sun.

Answer:
Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
The answer is D. Extracellular,
the main ions involve in osmoregulation in a cell are sodium and chloride. Intra-and extracellular distribution of K+ is
influenced, for example, by Na+/K+-ATPase
function, pH, Cellular catabolism and anabolism, Insulin and glucose. Parathormone
and calcitriol are important in the homeostatic regulation of phosphates.
