Answer:
On-site food services is the INDEPENDENT variable and the weight gain is the DEPENDENT variable
Explanation:
Variables can be dependent or independent. An independent variable is the one used by the researcher to test its degree of influence on the dependent variable. The dependent variable, as the name implies, relies on changes in the independent variable to effect its own changes.
In the question, it is obvious that weight gain among the first year students is dependent on on-site food services
Answer:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
<h2>password method</h2>
Explanation:
Rootkit virus is one type of virus which is hidden about its existence and tries to affect the maximum number of system.
Password method: This is a graphical method to identify the text hidden in the signature and confirming that it is not a robot or any other system to protect the system from hacking. This would be really hard-to-read and thus ensures safety.
Antivirus software: This is a system to protect the system, when the virus tries to attack the system. An indication will be given through the software to the user.
Answer:
Option B: DNS
Explanation:
Domain Name Server (DNS) is analogous to a phone book where people can look up a person name through numerical phone number. A DNS server is a database that host a database of public IP addresses (e.g. 64.233.160.0) and their associated hostname (e.g. google.com).
Whenever we type domain name in the address bar of our browser (e.g. google.com), that domain will be delivered to DNS server. Inside DNS server the URL will be mapped with its corresponding IP address making it possible for the web request to reach the the target server.
