How do plants and animals get nitrogen? Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants. When plants and animals die or when animals excrete wastes, the nitrogen compounds in the organic matter re-enter the soil where they are broken down by microorganisms, known as decomposers. What […]

What kind of observation lends supporting evidence to the solar nebula theory group of answer choices?
What kind of observation lends supporting evidence to the solar nebula theory group of answer choices? The observational evidence supporting this scenario include the infrared radiation we’ve detected from many nebulae where star systems appear to be forming. Also, other stars have flattened, spinning disks. Other support comes from computer simulations. Why is the nebular […]

How do cells gain energy?
How do cells gain energy? Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

How did Johannes Kepler impact the world?
How did Johannes Kepler impact the world? Tycho’s data let Kepler refine his model for planetary motion. It led him to create what we today call Kepler’s three laws of planetary motion. The first law of planetary motion states: Planets move around the sun in an elliptical orbit, where the sun is one of the […]
