<u>Answer:</u>
The human beings serve as replica/model of the mammals.
<u>Explanation:</u>
- A mammal is a vertebrate and it has fur, mammary glands (female) and feeds the young ones with milk, a neocortex (region of the brain) and three middle ear bones. This differentiates them from reptiles and birds.
- All mammals are 'warm blooded' because the body temperature heats the blood.
- A few mammals like the platypus lay eggs. The mammals are at the top of the food chain.
When pigments are mixed together, more colors are being absorbed which results to few colors that will be reflected. Each pigment absorbs and reflects light which results to the "color" or hue that we see. When these pigments are to be mixed, then more wavelengths would be absorbed which results to lesser reflection.
According to Jesse Kroll, an MIT professor of chemical engineering and civil engineering who specializes in atmospheric composition, the primary method used by scientists to quantify greenhouse gases in the atmosphere is spectroscopy. Thus, option A is correct.
<h3>What is the amount of carbon dioxide in the atmosphere?</h3>
Only 0.04% of the atmosphere is made up of carbon dioxide, and water vapor levels can range from 0% to 4%. However, while being the main greenhouse gas in our atmosphere, water vapor possesses “windows” that let some infrared light pass through without being absorbed.
Therefore, find a location outside with pure, unpolluted air, then use a special kind of flask to collect an air sample.

Bacteria and other small organisms within an ecosystem play an important role in maintaining homeostasis of an ecosystem while also helping to break down dead materials. These small organism play a vital role in decomposing of dead plant and animal matter that then becomes nutrients for the ecosystem in the future provide fertile soil for new plant life to grow supporting the cycle of life in an ecosystem.
