list five advantages and three disavantages of computer networks. Briefly discuss each. Solution ADVANTAGES OF COMPUTER NETWORKING Allows File Sharing Computer networking allows accessibility for the people to share their files easily. This greatly helps the people in saving their time and effort since they could already share some of the important files they need to share with other people effectively and accordingly. Provides Convenient Resource Sharing This is another benefit ...

Which of the following choices does BEST account for the ionic basis of the "all or none" threshold of an action potential? Voltage-gated calcium channels the sodium/potassium pump ligand-gated sodium channels at the axon terminal voltage-gated sodium channels at the axon hillock BOTH sodium and potassium leaky channels Solution Q: Which of the following choices BEST accounts for the ionic basis of the "all or none" threshold of an action potential? Answer: d) Voltage-ga...

which of the following is a function of the skin? protection sensory reception sythesis of vitamin d all apply Solution Skin performs all of these functions. It provides a protective barrier, it bears different types of receptors (pressure, heat, pain, vibrations, texture, etc.) for receiving external stimuli, and it synthesizes Vitamin D from fat in the presence of sunlight. Hence, all apply.

Prove that the set of fixed points of a linear transformation T : V rightarrow V is a subspace of V. Solution Dear William, In order to show that a subset P of a vector space V is a subspace of that vector space, we must show three things. First of all we must show that the 0 vector is contained in P. Secondly, we must show that if v and w are in P, then v+w is in P also. Finally we must show that if v is in P and c is a scalar, then cv is in P. The last two conditions are summa...

the function A=A0e^(-.0138x) models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the number of years since the material was put in the vault. If 400 pounds of the material are initially put into the vault, how many pounds will be left after 120 years? Solution A0 = 400 x = 120 A = 400 e^(-0.0138*120) = 76.36 pounds will be left

7000 6000 periodic peaks in E 5000 4000 3000 amplitude of the 2000 1000 0 70.5 Why are there the data? Why does the 81.5 92.5 115.5 59.5 150.5 peaks 1st increase, then decrease? 55 65 75 85 95 105 115 125 135 145 155 operator distance (bp) Solution Why there are periodic peaks in data There are periodic peaks in data indicating that the regions are repressions are almost equidistant. That is they are having equal distance in base pairs between them. Why the amplitude of first peak i...
