According to a life cycle analysis of the u. s. food system conducted by the university of michigan, the u. s. consumes 13.9 quads of mostly fossil fuel energy to produce 1.75 quads of food energy annually. a quad is a unit of energy equal to 1 quadrillion (1015) british thermal units (btus). one quad is equal to the energy of 183 million barrels of petroleum. here is how energy consumption breaks down by component in the u. s. food system: life cycle component description of component energy consumed per year (in quads) agricultural production energy used on farms, e. g., fuel, fertilizers, pesticides 2.0 transportation energy used to move food from where it is grown/made to where it is sold 0.5 processing industry energy used in processing food, including electricity 2.6 packaging material energy that goes into making the packaging for food and beverages 0.9 food retail and commercial food service energy used in grocery stores and restaurants 3.9 household storage and preparation energy used to operate refrigerators, freezers, ranges, and dishwashers 4.0 total energy consumed 13.9 source: center for sustainable systems, university of michigan. 2016. "u. s. food system factsheet." pub. no. css01-06. how could these data be best represented graphically?

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

radon is correct hope this

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
