20 pl Stem cells are important to development because they act as a blank
slate. The DNA from stem cells is replicated as seen with all living cells.
After mitosis, the new cells can differentiate into what the body needs
because the genes within the DNA may be turned on or off. There are
many factors that affect cell differentiation. Depending on these factors,
the proteins needed for gene expression are made from those specific
segments of DNA. Based on this information, select all the statements
below that are TRUE regarding this process.
All types of cells in a multicellular organism have the same DNA
Differentiation of cells may occur due to a difference in gene expression
Environmental factors such as temperature and light may have an influence on cell
differentation
Cell differentiation is influenced by how DNA is transcribed to RNA

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
