Many cells working together forms a tissue. Many tissues working together forms organs. Many organs working together forms organ systems. So it goes from general to most specific. Organ systems are needed in order for life. This proves that cells are the most basic units of life.
A doctor can use a 2D image model to show where the break is.
When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.
The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.
Each of these devices uses 2D image technology to show the result of the scan.
So, a model that can be used by a doctor to determine the location of the break is 2D image.

<h3><u>Answer;</u></h3>
Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.
<h3><u>Explanation;</u></h3>
- Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
- Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.
