The mass of an object stays the same no matter what you do to it.
Complete question:
Imagine a newly discovered biological molecule that is mostly hydrophobic in its structure. This new molecule will most likely be classified as a___________.
a. Proteins
b. Lipids
c. Nucleic acids
d. Carbohydrates
Answer:
b. Lipids
Explanation:
Lipids are the biomolecules that are mostly nonpolar in nature. Storage lipids such as fatty acids and oils have small or long chains of hydrocarbons. This makes them largely hydrophobic. Similarly, phospholipids have fatty acid chains that make their hydrophobic component. Steroids are also the lipids that have a distinct sterol nucleus in their structure. This makes then hydrophobic. Therefore, most of the lipids have structural components that make them largely hydrophobic molecules. So, the newly discovered molecule is most likely a lipid.

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option.
Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.

Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled.
In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
Answer:
Nitrogenous;Acid-Base and Fluid
Explanation:
The kidney is referred to as an excretory organ because it excretes nitrogenous wastes. It is also a major homeostatic organ because it maintains the electrolyte Acid-Base, and fluid balance of the blood.
