The proxy Server firewall makes requests for remote services on the behalf of the local clients.
A firewall is a security device in the form of computer hardware or software. It can help protect your network by acting as an intermediary between your internal network and outside traffic. It monitors attempts to gain access to your operating system and blocks unwanted incoming traffic and unrecognized sources.
Firewalls guard traffic at a computer's entry point called ports, which is where information is exchanged with external devices. For example, “Source address 172.18. 1.1 is allowed to reach destination 172.18. 2.1 over port 22." Think of IP addresses as houses, and port numbers as rooms within the house.

A. a structured test of a hypothesis
there are different steps to an experiment that you follow which prove the hypothesis (or educated guess) right or wrong
Answer:
he Mycenaean civilization, mainland Greece's first major civilization, dominated the Peloponnese in the Bronze Age from its stronghold at Mycenae in the north-east of the peninsula. The Mycenaean civilization collapsed suddenly at the end of the 2nd millennium BC.
Answer:a. Realistic Job Preview
Explanation: where the recruiter gives a detailed information about what the job involves.In this instance employees know what to expect in the job environment because of the detailed information has been given to the person that is employed.
In order to start DNA polymerase from scratch, the primase produces brief strands of RNA that attach to single-stranded DNA. Since the leading strand can only be replicated continuously in the 5' to 3' direction, this enzyme does not operate in any other orientation. Short Okazaki fragments are produced and subsequently joined together during lagging-strand replication.
DNA copies itself through a semi-conservative process known as DNA replication. The S Phase (synthesis phase) of the cell cycle is when DNA replication takes place. To guarantee that both dividing cells have a copy of the DNA in their nuclei, DNA replication must take place before a cell splits. DNA replication enzymes support the replication process. Two DNA strands comprise each DNA molecule. DNA has a double helix form, which resembles a twisted ladder. Replication of DNA occurs in a semi-conservative manner. Each daughter strand created when DNA is duplicated contains (conserves) one of its parent strands.
DNA helicase, RNA primase, DNA polymerase, and DNA ligase are the enzymes that are involved in DNA replication in that sequence. DNA helicase, an enzyme, assists in the double helix's unraveling during the replication process. A signal is subsequently sent to the enzyme DNA polymerase by RNA primase, which then creates an RNA primer on the parent strand. To create two new daughter strands of DNA, DNA polymerase then adds complimentary nucleotides to the parent strand. DNA ligase binds the Okazaki fragments together to create a new daughter strand of DNA once all bases have been paired with their partners (adenine with thymine and guanine with cytosine).
