There is a hypoxic dead zone in the Gulf of Mexico due to nitrogen-rich runoff from the Mississippi River. When the Mississippi

flows into the Gulf of Mexico, it introduces high levels of organic pollutants and nitrates from fertilizers. The presence of these excess nitrogen-rich substances in the Gulf of Mexico leads to a sequence of events that results in the hypoxic dead zone. Put these events, which are listed below, in sequential order.

Energy enters most ecosystems as sunlight. Within an ecosystem, energy is transformed, used, and exits the ecosystem as heat. Dr
Cloud [144]

Answer: The correct terms for completing the concept of energy and trophic levels are as follows-

a) Solar energy

b) Trophic levels

c) Heat

d) Tertiary consumers

e) Secondary consumers

f) Primary consumers

g) Primary producers

h) Decomposers.

Energy flow in an ecosystem is driven by solar energy that is captured and converted into chemical energy by primary producers ( like green plants and algae). The energy moves through different trophic levels according to the 10% law of energy transfer and the rest energy is released as heat.

Primary producers are eaten by primary consumers, which are eaten by secondary consumers that are eaten by tertiary consumers. The organic matter that becomes dead is ultimately decomposed with the help of decomposers.

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.

Which situations would be most likely to engage the anterior cingulate cortex?
maria [59]

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.
