Answer:
But what does “waxing and waning gibbous” mean? Rob says crescent is when you can see less than half of the moon illuminated. “Gibbous, you attach that to either waxing or waning when you see more than half of the moon illuminated,” he said. Waxing means it's getting bigger while waning means it's getting smaller.
Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate.
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>
