Answer:
Option (4) is the correct answer.
Explanation:
In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".
But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--
a.add(element); //where add is a function, element is a value and a is a array list object.
Another option is invalid because--
- Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
- Option 2 gives a compile-time error because add functions bracts are not closed.
- Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.

Answer:
The body of water that is most likely to be a marine ecosystem would be an estuary.
Explanation:
An estuary is a widened, often funnel-shaped mouth of a river, where fresh river water and salt sea water are mixed and thus brackish water is created, and where tidal differences can be observed. When a river flows as a system of branches, it is called a delta.
Estuaries often have a great natural value. They typically consist of swallows and salt marshes that are very rich in invertebrates and thus have a great attraction for birds, among other things.
Answer:
MARKET PARTICIPATION.
Explanation:
<em>Because this way the firm size can stay constant or contract even if the company increases its revenues. Information technology helps firms contract in size because it can reduce transactions costs. According to the transaction cost theory, firms and individuals seek to economize on transaction costs, much as they do on prodcution costs. For instance, by using computer links to external suppliers, the Chrylser Corporation can achieve economies by obtaining more than 70 percent of its parts from other companies.</em>
