Superdense Coding We wish to transfer a 256-bit key between a sender and receiver using superdense coding. For this transfer, both parties should a-priori exchange at least Bell pairs and then quantum bits to transfer the key. Answer the following two questions, you must report numerical answers.

A scientist discovered plant life on Mars. She brought it back to the space station to test the leaves of the plant in order to determine what type of pigments functioned best on Mars. Only a single pigment, pigment A, was found. The absorption spectrum of pigment A is shown below. What is the independent variable in this graph?

The SARS-CoV-2 virus responsible for the current COVID-19 pandemic gains entry by binding to angiotensin-converting enzyme 2 (ACE2) receptors found on the surface of numerous types of cells, enabling the virus to infect a wide range of cell types and result in systemic damage. The structure of ACE2 is shown below as a ribbon diagram. Copyright 2024 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.

A teratoma is a tumor composed of several different types of tissue that can include muscle, teeth, hair, or bone. Teratomas develop from germ cells, a type of cell that gives rise to gametes. Because germ cells are not differentiated into specific cell types (as are e.g. muscle cells, skin cells, fat cells, etc.), teratomas can develop exhibiting numerous different cell types, giving them their name teratoma, Greek for “monstrous tumor”. Teratomas may be benign or cancerous. As a result of mistakes in processes of cell division, they are generally diploid, and sometimes polyploid. Consider a cell of a teratoma and a healthy human epithelial (skin) cell. Now consider the DNA and the three types of RNA (mRNA, tRNA, and rRNA) found in both cells. For each of these (DNA, mRNA, tRNA, and rRNA), compare what you would expect to find in both the teratoma and a healthy cell. Would the DNA and RNA be the same, or different, or a mixture of same and different, in both cells? Please explain briefly but clearly for each of these four nucleic acids and provide examples or reasons. Label each of your answers 1 through 4 and write a short paragraph (a sentence or two) for each. Copyright 2024 by Edmonds College Department of Biology. All rights reserved.
