Answer:
Cell signaling involves three stages that are reception of signal molecules by the cell surface receptor, transduction of that signal molecules and response of the signal molecule.
Reception: In reception, the items that are involved are receptor molecules and cell surface receptors like G- protein-coupled receptors, receptor tyrosine kinase, enzyme-linked receptors.
Transduction: In transduction, the items involved are adenylyl cyclase, phosphorylation cascade, second messenger like cAMP, DAG and IP3.
Response: The response of cell signaling is the starting of molecular processes and the production of proteins.
Lamarck believed that an organism that adapted to change would pass that adapted trait to it's offspring. he was incorrect because those changes dont get passed on through genetics
Answer:
Human genetic variation generally is distributed in a continuous range, with varying clusters of frequency. The significance we give our variations, the way we perceive them—in fact, whether or not we perceive them at all—is determined by our culture
Explanation:
Answer:
C
Explanation:
Let's look at the cellular respiration equation
oxygen+glucose--> water + carbon dioxide + ATP
In the process, oxygen is used. We inhale oxygen and use it in cellular respiration. We then create carbon dioxide which is exhaled out. We don't use the carbon dioxide, so it is the waste product.
Therefore, the answer is C. Oxygen is used, and carbon dioxide is released as waste.
