Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. Magnesium is an important component of chlorophyll. The concentration of magnesium ions is higher in the root-hair cells of plants than in the soil.
The correct answer is C. It is so strict because a foreign species could compete with a native species and drive it to extinction.
The Hawaiian islands are one of the geographical isolated islands which faces the problem of the invasive species affecting the biodiversity of the island negatively.
The foreign species is equipped better to survive in the Hawaiian habitat and competes with the native species for the resources and food. The interaction and competition of the foreign species in the Hawaiian environment and habitat limits the resources for native species which increases the chance of the native species getting endangered.
The Hawaii Invasive Species Council along with other bodies such as department of agriculture, department of business and economic development, private and other government and non-government bodies have taken initiatives towards eradication of invasive species by strict laws.
Answer:
The formation of favorable C-bond ionic or C-bonding interactions in a folded protein replace interactions between solvent (water) and the ionic species (or restore donors and acceptors) in the unfolded state. The favorable ΔH obtained by formation of H-bond in the H-bonding protein is offset by the energy required to break many interactions, with solvent going from the inter-molecular to the intramolecular state.
