Angelica is an engineer who is designing a system of solar panels that will be placed on the roofs of houses in a new neighborhood. Which of the following factors are most important for her to take into account to ensure that her design is successful? A.
the season in which the solar panels will be installed and the cost of the needed materials
B.
the time it will take to install the solar panels and how many cars will be parked at each house
C.
the width of the streets in the neighborhood and the time it will take to install the solar panels
D.
the cost of the needed materials and the area of each roof that is frequently exposed to sunlight

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
