Answer:

Crossing over.

Explanation:

Crossing over is the process of exchange of genetic material between two non-sister chromatids of a homologous chromosome pair. It occurs during pachytene of prophase I of meiosis I. Crossing over creates new gene combinations that were otherwise not present in the parent cells. In this way, genetic variations are created by crossing over.

Mnenie [13.5K]

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.

olganol [36]

Answer:coconut oil, butter, palm oil, olive oil, canola oil.

Explanation: .

A saturated fat one whose fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules which are glycerol and fatty acids. Fats are made of long chains of carbon (C) atoms while some carbon atoms are linked by single bonds (-C-C-) bonds others are linked by double bonds (-C=C-). These Double bonds will react with hydrogen to form single bonds causing them to be SATURATED, because when the second bond is broken, each half of the bond is then saturated with a hydrogen atom.

In terms of saturated fats acids composition by percentage according to ChartsBin statistics collector team 2011, Fat Composition in different Cooking Oils, ChartsBin.com, palm oil is 14.192, coconut oil is 91.92 canola is 7.46,palm oil 51.57, butter 65%-68%.Here you can see that the order of saturated fats from the highest gives- Coconut,butter, palm oil,olive oil and Canola as the last
