The number of electrons forming a charge cloud around the nucleus is (pick one of the following) greater than; equal to; smaller than the number of protons in the nucleus of the atom.

Paragraph 1 - How the Law of Conservation of Matter is supported by the experimental demonstrations: In the law of conservation particles and materials are neither created nor destroyed . It was similar towards the experimental demonstrations because nothing changed or destroyed in the processes .Kinetic and potential energy was used in the experiments.

[3] M. Bellare, S. Keelveedhi, and T.Ristenpart. Dupless: Serveraided encryption for deduplicate storage. In USENIX SecuritySymposium, 2013.

Encyption takes data and transforms it into unreadable jargon until a key is used to unlock or decrypt the data back to its original form. Due to its near infallibility, encryption is one the most best ways to secure data (Williams & Sawyer, 2015).

Based upon my extensive knowledge, training and experience, I have reasonably determined that when trying to locate the particular information pertain to the investigation it is general practice to have the electronic storage devices searched by an individual that is well qualified when dealing with computer technology especially in different types of environments. This is key because we need to make sure that all the electronic data is complete and pertains to the search warrant without going beyond the scope of it. To properly examine the electronic data in question it would be more efficient to perform an image copy on the drive where it could be examined at a later time in a laboratory. This is correct for the following

Results: After the first two days, there were no results as I expected. Once the third day arrived, I checked at about 2:00 p.m. and noticed a slight stem coming from a few of the beans that were placed outside in the sunlight. That made my results clear that bean seeds germinate fastest outside with the sun shining down upon them. The fourth day brought more growth to the ones outside in the sunlight and some growth with a tiny stem for the ones inside (room temperature) with sunlight.

Electronic evidence is very fragile because it can be destroyed or altered very easily, therefore it is imperative that investigators follow very careful all the procedural steps when collecting electronic evidence (Diversified Forensics). Before any electronic evidence is gathered investigators should determine whether there is probable cause that a crime has been committed, or if the crime was committed somewhere else the investigator should determine whether the electronic evidence will aid the investigation process to prove or disapprove the crime, if a warrant is needed it must be obtained prior to collecting the evidence (Diversified Forensics). Hard drives, computers, and other electronic devices must be turned off, unplug all cables,

Darwin's Theory of Evolution is the commonly thought notion that all life is linked and has descended from a common ancestor. Darwin's general theory assumes the development of life from nonlife and stresses a purely naturalistic "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. “Natural selection is a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits” (Campbell, 2014). How Darwin came about to these findings was by exploring the Galapagos Islands. It took years of research for him to come up with conclusions. He focused on

Where can you store your public keys or public certificate files in the public domain? Is this the same thing as a Public Key Infrastructure (KI) server? you can import or export certificates from any of the folders in the certificate store. Additionally, if the private key associated with a certificate is marked as available for export, you can export both into a PKCS #12 file.

Just as other forms of evidence, digital evidence must be assured not to get wet, stepped on, driven over, and frozen and so on. Magnetic media of all sorts can be fragile and if not handled with care can be wiped out. this is why officers should take special care to handle the evidence and package it accordingly as not doing so would cost them a case. Third issue that can also affect digital data if not done properly is the turning off or powering down a device. Computers store information on the RAM system which can be erased if not closed properly. As well the computer may have applications, documents, images, or any other data may have been left opened by the user can be erased if the computer is turned off. It is best that the investigator not to commit any action when dealing with an computer such as clicking the mouse, clicking on any files, using the keyboard, or apply any software to the suspects computer

The three items that I would collect would be the external hard drive, the laptop, and the USB thumb drive. It’s important to remember that you ”must use caution when collecting, packaging, or storing digital devices to avoid altering, damaging, or destroying the digital evidence. Avoid using any tools or materials that may produce or emit static electricity or a magnetic field as these may damage or destroy the evidence” (Mukasey, 2008). The first item that I would collect as digital evidence would be the external hard drive. It may contain all types of evidence such as: files, logs, pictures, recordings, or even video logs. Before collecting it as evidence I would take pictures of the hard drive, making sure to get the manufacturer and serial numbers, and then document it. Once complete, I would seal it in an anti-static bag and label that as well. The second item that I would collect would be the laptop. This could have all of the same type of information that the hard drive has and also may contain copies, pictures, or the source code itself from “Product X.” The laptop may show whether or not he was sharing files or trade secrets with outside sources, or even if he were attempting to crack passwords so as to get into systems that weren’t available to

Practitioners make user of what is called a “forensic kit” in order to image or procure the files from the storage devices in possession of the custodian. Reactive responses are also known as “incident response”. As mentioned in a paper by SANS Institute, a good incident response procedure can be broken down into some basic steps [6] – planning and preparation, incident detection, initial response, response strategy formulation, forensic backups, investigation, security measure implementation, network monitoring, recovery and reporting. More details about each step can be found in the paper. To accommodate these requirements, the forensic kit includes various hardware and software that assists in these phases in a collection process. Below are some types of forensic kits that are used in the computer forensic industry

1TB hard drives will be used in case the size of the data exceeds the size limit of 500GB. Every hard must be appropriately labeled according to the every case. Some of the hard drives will be used for short term storage until the investigation for the case is completed. Then, the evidence will be stored in hard drives specifically for long term storage and will be physically stored in a closet or cabinet that has at least one security measures. Some examples of security measures for the closet or cabinet are key locks, PIN code access, or a fingerprint lock. In addition to closet or cabinet security measure, the hard drives will be secured using symmetric encryption. Only the forensic investigators should know the secret key. After the evidence is stored in the long term hard drives, it also needs to be have a backup. All of the backups form the hard drives will be stored in an 180TB storage pod that costs around $2,000.00. The storage pod will hold all of the most important evidence of all of the cases. The storage pod needs to be located in another building.

BitLocker will encode the whole drive. The encryption is straightforward to clients who sign on the framework. That is, they can work with their records in ordinary way while the framework plays out the encryption and decoding for them naturally.
