Ecology
Ecology studies the life of living things and their environment.
<span>TESTING HYPOTHESIS ABOUT INDIVIDUAL REGRESSION COEFFICIENTS: t STATISTIC) : The t statistic. Used to determine which of the independent variables influences the dependent variable. Whether a particular independent variable influences the dependent variable Test whether the true value of the parameter estimate is zero. The higher the value of the t-statistic, the smaller the value of the regression coefficient is zero.</span>
Answer:
Euhaline ⇒ Polyhaline ⇒ Mesohaline ⇒ Oligohaline
Explanation:
Let's first define each of these levels:
- Polyhaline: a category of salinity that has medium-high levels of salt
- Mesohaline: a category of salinity that has medium levels of salt
- Oligohaline: a category of salinity that has low levels of salt
- Euthaline: a category of salinity that has high levels of salt
Now, we can order these in decreasing order of salinity:
Euhaline ⇒ Polyhaline ⇒ Mesohaline ⇒ Oligohaline
Rapid environmental changes can cause:
1) Species can become vulnerable to extinction.
2) A decrease or increase of populations.
3) Diversity of species.
Answer:
This is an example of scope creep.
Explanation:
In project management, scope creep signifies the changes, uncontrolled or continuous growth in the scope of a project, at any time after the initiation of the project. This can take place when the project's scope is not adequately documented, defined, or monitored.
The main reasons for scope creep are poor requirements analysis, underestimating the complexity of the project, not involving users early enough, and lack of change control. Thus, the given case is an illustration of scope creep.
