Global phytoplankton levels

makvit [3.9K]

Answer:

is used by commercial airplanes

Explanation:

The stratosphere is used by most commercial airplanes. This is because this layer of earth is stratified and more stable.

The lowest level of the atmosphere is the troposphere.
This layer is where all the bulk of the atmospheric gases are domiciled.
Weather conditions occur here.
This layer is not safe for flight due to its turbulent nature.
The ionosphere is responsible for the transmission of radio signals around the earth.
The earth's weather occurs in the region of the troposphere.

What defines a symbiotic relationship?

rjkz [21]

Answer:

Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism! Hope this helps! you can simplify this answer!

31. The data in the accompanying graph show evidence of disease in the human body. D 38 - - E Body Temperature (°C) 377 А IDOT B

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. A disruption in dynamic equilibrium is indicated by the temperature change between point C and D. Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a restricted range around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

The restricted range of homeostasis at a constant temperature around 37ºC.

Six reference points (A-F) withing 12 hours.

Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.

A disruption in dynamic equilibrium is indicated by the temperature change between point C and D.

Use the drop-down menus to put the stages of technological design in chronological order

notsponge [240]

Answer:

Identify a problem or need.
Design a solution.
Implement a solution.
Evaluate the solution.

Explanation:

Technological design refers to the process followed for the development of new technologies. A logical sequence is followed to move forward to each step to ask questions and provide solutions to the process. Various steps are followed in the process of technological design. The first step in the process is to identify the problem. Designing a solution follows the second step. The third step is to implement the solution. The fourth step is to evaluate the solution and find whether it is intending towards finding the solution or not.
