Given an array A[1..n] representing a sequence of n integers, a subsequence is a subset of elements of A, in the same order as they appear in A. A subsequence is monotonic if it is a sequence of strictly increasing numbers. Define LMS(i) to be the length of a longest monotonically increasing subsequence of A[1..i] that must have A[i] as its last element. Write a recurrence for LMS(i) and convert into a dynamic program that calculates LMS(i) for i=1..n. What is the running time of your algorithm?

An NMOS transistor is fabricated in a 0.18-m process having = 400 A/V2 and = 5 V/m of channel length. If L = 0.54 m and W = 5.4m, find VA and . Find the value of iD that results when the device is operated with an overdrive voltage of 0.25 V and vDS = 1 V. Also, find the value of ro at this operating point. If vDS is increased by 0.5 V, what is the corresponding change in iD?b) If in an NMOS transistor, both W and L are quadrupled and VOV is halved, by what factor does ro change?

Justify the claim that metabolic pathways evolved on Earth by connecting environmental changes that occurred to their development.a. The earliest pathways that developed on Earth were aerobic because the primitive atmosphere did not have oxygen. These pathways were used by primitive Archaebacteria. Over time, photosynthesis developed, which led to increased oxygen in the atmosphere. This allowed anaerobic cellular respiration.b. The earliest pathways that developed on Earth were anaerobic because the primitive atmosphere didn't have oxygen. These pathways were used by primitive prokaryotic microorganisms. Over time, photosynthesis developed, which led to increased oxygen in the atmosphere. This allowed aerobic cellular respiration.c. The earliest pathways that developed on Earth were anaerobic because the primitive atmosphere had oxygen. These pathways were used by primitive prokaryotic microorganisms. Over time, organisms carrying out fermentation stabilized oxygen levels in the atmosphere. This allowed aerobic cellular respiration.d. The earliest pathways that developed on Earth were anaerobic because the primitive atmosphere didn't have oxygen. These pathways were used by primitive prokaryotic microorganisms. Over time, the respiration of Eubacteria and Archaebacteria led to increased oxygen in the atmosphere. This allowed aerobic cellular respiration.

Enter your observations for (CoCidl (procedure step 1) Addition of DI water (procedure step 2) The step one is a light blue and after adding 30 drops of deionized water to the beaker using a Pasteur pipette and mixing well the color turned to a deep purple tone and this is the equilibrium mixture. From the procedure 3. Prepare 6 clean, dry test tubes. Label them 1 thru 6. Divide the equilibrium mixture equally among the 6 test tubes. Your first test tube is the reference test tube. 4. Add one drop of concentrated HCl to test tube 2 and mix well. Compare it to the reference tube and observe color changes. 5. Add 3-4 drops of delonized water to test tube 3 and mix well. Compare it to the reference tube and observe color changes. Remember the solvent in this part is ethanol. Water is considered to be a reactant 6. Add one drop of 0.02 M AgNO3 to test tube 4 and mix well. Ag+ reacts with Cr to form trueDensity AgCl effectively removing Cr from solution. Let the trueDensity settle, compare it to the reference tube and observe the color changes
