Answer:
That sample, nicknamed the Genesis Rock, sample number 15415, was an anorthosite, a piece of the moon’s primordial crust. Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason. While not the oldest lunar sample brought back from the moon, geologists at the Manned Spacecraft Center (now known as the Johnson Space Center) later concluded that this rock was about 4 billion years old

Correct answer - Short term energy.
Why? - The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology.
Answer: B. prevent the internal environment from changing
Explanation: homeostasis actually helps the internal environment keep a stable, constant, condition.
Answer:
The correct answer is A. energy was required to produce the concentration gradient.
Explanation:
There are two types of transport through which a molecule moves in and out of the cell and these are active transport and passive transport. In passive transport, the molecule moves without the help of energy because they move down there concentration. So in passive transport, if concentration gradient changes then passive transport will take place.
In active transport, the molecule move against their concentration gradient with the help of energy or ATP. So in passive transport, the concentration of molecule can be high in the cell because its transport occurred against the gradient with the help of energy. So the correct answer is A.
