In dogs, genes a and b are required for scent. individuals homozygous for either one or both of the nonfunctional recessive alleles are not able to smell. if a large number of matings were made between two double heterozygotes, what percentage of offspring would not be able to smell? express your answer as a fraction (i. e. 1/10)

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
