<span>An essential functional group involved in cellular energy transfer is the phosphate group.
It is important because it is charged and can release H+ ions into the solution. This makes the group highly acidic, which is important when it comes to the transfer of energy within a cell. Apart from the phosphate group, hydroxyl, carbonyl, amino, and other are also important.</span>
Answer:
Hurricanes will become more frequent and expand to new areas.
Explanation:
Global warming will rise sea temperatures worldwide. This means conditions for hurricanes will be met more often (they only form in higher than average sea temperatures). That means more hurricanes will form in the future. Also because of rising sea temperatures new areas will be effected by hurricanes as they will meet the threshold required for hurricanes to form.
A- the ratio to surface area
In ecology, productivity refers to the rate of generation of biomass in an ecosystem. It is usually expressed in units of mass per unit surface (or volume) per unit time, for instance grams per square metre per day (g m−2 d−1). The mass unit may relate to dry matter or to the mass of carbon generated. Productivity of autotrophs such as plants is called primary productivity, while that of heterotrophs such as animals is called secondary productivity
