1. If there are n-gene pairs controlling a quantitative trait, then a parent that is an heterozygote (with one additive allele and one non-additive allele for each gene) will produce different kinds of gametes with respect to the number of additive alleles present: A. 2n (ranging from 0 to 2n additive alleles per gamete) B. 2n 1 (ranging from 0 to 2n 1 addtive alleles per gamete) C. n-1 (ranging from 1 to n-1 additive alleles per gamete) D. n (ranging from n 1 to 2n additive alleles per gamete) E. n 1 (ranging from 0 to n 1 additive alleles per gamete)

Will mark you as ! keiko’s teacher was discussing the theory of endosymbiosis. she asked keiko to mark the organelles in the diagram that most closely resembled prokaryotes. which organelles should keiko mark? * the first image is the question and the second image is some information to you answer the !

How are fungi more like an animal? they have a cell wall. they are heterotrophs that absorb their food. they produce seeds and have membrane-bound nucleus. they use sunlight for photosynthesis.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
