Answer: The correct answer for the first question is- A) species vary globally .

As per the information given in the question, Marine iguanas are found only on the galapagos islands. This indicates that throughout world, different species are found and some species are restricted to a particular area due to particular environmental conditions. Therefore, it can be said that species vary locally.

The correct answer for second question is- D). evolution is the process through which species change over time.

Evolution can be described as a process of change in the characteristics of organisms over many generations. It can be driven by various mechanisms such as natural selection, genetic drift.

• Marine iguanas are found only on the Galapagos Islands.

• Evolution is the process through which species change over time.

Further Explanation:

The climate changes, continental shifts, availability of food, and other geological changes are responsible for the variations that occur over time. The changes in the environmental conditions lead to evolution, whereas, during the periods of environmental stability, the evolutionary variations are limited. Substantial and evolutionary changes are the result of artificial selection.Fossil record helps to determine more direct evidence for evolution to occur over some time.It is examined that rates and direction of evolution have varied widely over time. Therefore evolutionary change has been far from constant and uniform. Some periods show little observable change and some periods show a great diversity.

Different species of iguanas are present on a different island. But marine iguanas are only present on Galapagos Island because they have evolved in such ways that only adapt or thrive in marine habitats. Also, the availability of insects and fishes (food) in water allows them to proliferate or survive in marine conditions.

Name and briefly describe the three essential principles of test construction ap psych

Natasha_Volkova [10]

<span>The three essential principles of test construction are listed below:
I. Standardization
II. Reliability
III. Validity

</span>Standardization- To standardize a test means that test is given to a large, representative sample of people, in order to establish the norms that future test takers are compared against (using a normal distribution)

Reliability - This principle requires that a test must produce reliable, consistent results when it is repeated. The reliability of a test can be verified using the test-retest method or the split-half method.

Validity - This refers to the ability of a test to measure what it was designed to measure.

S<em>ince Schleiden and Schwann’s experiments proved that certain tissues were made up of cells (and those tissues are from living organisms), it most closely relates to the part that all living things are made up of cells.

Answer:

The carrying capacity of a wildlife reserve is 570 individuals for a particular species of rodents. If the area of the reserve is extended, the carrying capacity is likely to Increase

During the summer, a fatal disease began killing individuals. The carrying

capacity of the reserve will therefore decrease

Explanation:

The carrying capacity of a habitat is the maximum number of individuals of a given species it can support without depleting the available resources. When the area of the reserve is extended, the carrying capacity increases because the available resources will also increase. A fatal disease would increase the carrying capacity since the number of wildlife would decrease.
