These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material!

Show me the steps to solve After the firm has successfully completed steps one and two, it discovers an alternate production process that would cost $150,000 and would lower production costs by $1,000,000 with certainty. This process, however, is a substitute for the three-step cost-saving process; they cannot be used simultaneously. Furthermore, to have this process available, the firm must spend the $150,000 before it knows if it will successfully complete step three of the three-step research project. f) Draw the decision tree faced by the firm after it has successfully completed steps one and two, including the possibility of pursuing this alternate production process

11 1 point Interspecies breeding between two species of lilies (flowering plant) produces a sterile hybrid which is reproductively isolated from the parental species but may propagate asexually. In subsequent generations a fertile polyploid orchid is produced forming a new species. The most likely mechanism to account for the formation of the fertile polyploid was a... mitotic error cross-fertilization meiotic error inbreeding physical barrier

If the intracellular domain of a "red" cell-surface receptor is swapped with the intracellular domain of a "blue" cell-surface receptor, then: - The blue ligand will activate the blue pathway - Both pathways will be activated without any ligand - The red ligand will activate the blue pathway - The red ligand will activate the red pathway - The blue ligand will activate the red pathway In a signaling pathway, reception causes an increase in cytoplasmic levels of Ca++ that induces gene expression changes. If you pre-treat the cells to remove all the available Ca++ prior to exposing them to the ligand, the cells will:

In the winter sport of bobsledding, athletes push their sled along a horizontal ice surface and then hop on the sled as it starts to careen down the steeply sloped track. In one event, the sled reaches a top speed of 9.2 m/s before starting down the initial part of the track, which is sloped downward at an angle of 9.0° What is the sled's speed after it has traveled the first 60 m? Express your answer with the appropriate units.
